The treatment of acquired dermal macular hyperpigmentation depends on the subtype and its duration, but many therapies have been tried with little or no benefit. Any identified contact allergen should be avoided. Colchicine has been used to improve macrophage activity and thus clear dermal pigmentation treatment of melasma. According to it, patients with mild melasma can use HQ 4%, or triple combination therapy with 4% HQ + 0.05% RA + 0.01% fluocinolone acetonide, or dual therapy, or non-phenolic therapy if there is sensitivity to the cited agents.21For cases o To assess treatment response of mycophenolate mofetil in patients having acquired dermal macular hyperpigmentation. Material and Methods. In this open‐label, pilot study, patients of acquired dermal macular hyperpigmentation affecting at least the face and/or neck were included. Each participant was treated with mycophenolate mofetil 2 g/day.

EDP is very difficult to treat, and there is no consistently effective treatment. Oral corticosteroids, antibiotics (e.g. doxycycline), antimalarials, isoniazid, griseofulvin and UV radiation therapy have produced variable results. Successful treatment with dapsone and clofazimine has been reported in small series On physical examination, the patient appeared to be in good general health. Extensive bilaterally symmetric reticulated macular hyperpigmentation was present on the extremities, the posterior and lateral aspects of the neck, and the upper chest and back, sparing the interscapular areas (Figs 1 and 2) Treatment options for postinflammatory hyperpigmentation, melasma, solar lentigines, and ephelides include the use of topical agents, chemical peels, cryotherapy, or laser therapy. Café-au-lait.. Context: An umbrella term, acquired dermal macular hyperpigmentation (ADMH), has been proposed to denote conditions including ashy dermatosis, erythema dyschromicum perstans, lichen planus pigmentosus, and idiopathic macular eruptive pigmentation.Aims: To classify the patients manifesting ADMH on the basis of histology.Settings and Design: In this retrospective, cross-sectional study.
Hyperpigmentation is a feature of a multitude of clinical conditions, ranging from normal variations of skin color to acquired and inherited syndromes, and is one of the most common reasons for dermatologic consultation, particularly in patients with darker skin types .

Idiopathic eruptive macular pigmentation, rare case. Introduction Idiopathic eruptive macular pigmentation (IEMP) is a rare pigmentation disorder which is categorized as the acquired dermal hyperpigmentary disorders.1 It is usually found in children and adolescents.2,3 Diagnosis of IEMP is established based on characteristi Abstract. Skin is the largest organ of the body that has both cosmetic and protective value. But under the influence of certain heredity and environmental factors certain skin disorders such as acquired dermal macular hyperpigmentation occur in the people which usually presents with slate grey or brownish-black blue, brown macules, which can change in morphology and size over time Vinay K, Bishnoi A, Parsad D, Saikia UN, Sendhil Kumaran M.

Ashy dermatosis is a pigmentary disorder on the spectrum of acquired macular pigmentation of uncertain etiology.1 It is most prevalent in patients from Central and South America and is characterized by widespread blue-gray macules with predilection for the face, neck, trunk, and upper extremities. Dermoscopy may show gray-blue dots corresponding to melanophages in the dermis, and histology. Lichen planus pigmentosus, erythema dyschromicum perstans and idiopathic eruptive macular pigmentation are the three most commonly accepted subtypes of acquired dermal hyperpigmentary disorders. While some patients fit easily into one of these subtypes, others do not. Overlapping features of several subtypes may also be seen in the one patient The similar recognizable clinical pattern in all 25 children suggests that this facial macular hyperpigmentation is a distinct entity. Acquired, nonsegmental, hyperpigmented lesions in infants and young children are most commonly postinflammatory and transient in nature. We describe 25 infants and young children with long-lasting, noncongenital. Macular NS responds better to treatment than papular, but recurrences aren't infrequent. Becker's naevus (BN): Management is highly variable, and removal carries scarring and dyspigmentation risks. Long-pulsed laser effectively removed BN-associated hair, but its less efficacious in hyperpigmentation treatment Treatment options for postinflammatory hyperpigmentation, melasma, solar lentigines, and epheli- des include the use of topical agents, chemical peels, cryotherapy, or laser therapy.

Background: Hyperpigmentation is a common dermatologic problem that may have substantial impact on the patient, since it affects the appearance and quality of life, and may influence treatment adherence. There are few studies of drug-induced hyperpigmentation. Methods: We studied drug-induced hyperpigmentation in patients attending an outpatient dermatology clinic in the Western Area of. Hypopigmentation is the loss of skin color caused by a reduction in melanin content. Although most often benign, acquired hypopigmented disorders can have significant cosmetic, psychological, economic, and societal consequences.1, 2 Investigational studies are often nondiagnostic, and therefore a systematic approach and recognition of key clinical features is critical in distinguishing between.
Epidermal hyperpigmentation manifests as light brown to black pigmentation, whereas dermal hypermelanosis confers a darker grey appearance to lesions. Figure 1 demonstrates post-inflammatory hyperpigmentation after acne on the back of a patient. Figure 2 is an image of post-inflammatory hypopigmentation from eczema on the arm of a child Epidermal hyperpigmentation (e.g., associated with acne) occurs when increased melanin is transferred to keratinocytes while dermal pigmentation (e.g., associated with lichen planus and cutaneous lupus erythematosus) occurs when the basement membrane is disrupted and melanin falls into the dermis and resides within melanophages.
Skin pigmentation disorders. Skin pigmentation disorders can be due to changes in melanin. Melanin is a skin pigment produced by melanocytes situated in superficial layer epidermis, gives color to the skin, hair, and eyes. Melanin composition differs, fairer skin has a low composition and darker individuals with a high composition of melanin • A macular, linear, hyperpigmented lesion developed on a 34-year-old woman's leg in the area innervated by the sural nerve. Light and electron microscopic study of the lesion showed superficial dermal melanocytosis. To the best of our knowledge, this lesion is distinct from previously described.. Epidermal hyperpigmentation is tan, brown, or dark brown in color and may persist for months to years without treatment but does tend to improve over time as the underlying inflammatory disorder resolves. Wood's lamp examination of epidermal PIH may reveal fluorescence. Dermal hyperpigmentation is blue-gray and may be permanent Hypermelanotic skin disorders that involves the hidden area of the body involves a wide range of diseases that includes Mastocytosis, post inflammatory hyperpigmentation, cutaneous amyloidosis, inherited lentigiosis, and the three disorders: Erythema dyschromicum perstans (EDP), Idiopathic eruptive macular pigmentation (IEMP) and Lichen planus pigmentosus (LPP)
Melasma is an acquired brown macular hyperpigmentation usually of the face. It is far more common in females than in males. It usually presents bilaterally and symmetrically on the face, but extensor forearms may also be involved. There are believed to be three histologic variants of melasma: epidermal, dermal, and mixed dermal and epidermal Lichen planus pigmentosus (LPP) is an acquired dermal pigmentary disease with an unclear nosological status .The term LPP was initially coined since it was considered to be a macular variant of lichen planus (LP), with some patients exhibiting evidence of classical LP elsewhere .However, both dermatoses demonstrate stark clinical differences . It is far more common and persistent in darker skin types (Fitzpatrick Types III-VI) and can be characterized by epidermal as well as dermal melanotic hypermelanosis. A Wood's lamp examination can determine depth of the hyperpigmentation
Dermal melanophages, possible mild interface dermatitis LP should be considered in the differential diagnosis for patients with acquired macular hyperpigmentation, but patients who have pruritic papules with residual hyperpigmentation should be diagnosed as having LP with post-inflammatory hyperpigmentation, and not LPP. It was also. Melasma with dermal involvement is the most difficult pattern to manage, whilst the epidermal pattern tends to respond more favourably to treatment [37,38]. Differential Diagnosis. Postinflammatory hyperpigmentation due to cutaneous lupus, atopic dermatitis, contact dermatitis, photocontact or photosensitivity reactions may present with similar.

Acquired dermal melanoses are heterogenous entities with the common features of pigment incontinence and dermal melanophages resulting in greyish macular hyperpigmentation. This article reviews the current literature on laser toning in melasma and the role of the Q-switched Nd:YAG laser in stubborn pigmentary disorders such as lichen planus. acquired disorder of hypopigmentation or hyperpigmentation macules and patches fine scale that may only be apparent with scratching of the skin often the result of a fungul infection -Malassezia furfur diagnosed by KOH prep treatment with topical and oral antifungal Acquired dermal macular hyperpigmentation (ADMH) is a hypernym encompassing Riehl's melanosis, lichen planus pigmentosus, and ashy dermatoses that show significant clinicopathological overlap. We sought to describe the dermatoscopic features of ADMH and correlate them with histopathological findings.This was a prospective observational study. The Mongolian spot, nevi of Ota and Ito are the most common morphological forms. We report a case of a 24-year-old Caucasian woman presented with a 10-months history of progressive darkening of the right side of her upper back. Cutaneous examination revealed a macular blue-grey hyperpigmentation of the right side of her upper back Abstract Disorders of hyperpigmentation usually result from an increase in melanin production, which is occasionally associated with an increased density of active melanocytes. Skin discoloration may also be caused by dermal deposition of exogenous substances such as drugs or heavy metals. Clinically, disorders of hyperpigmentation can be classified into diffuse, circumscribed, linear, and.
The knowledge of this disease is important in order to avoid unnecessary treatment as spontaneous resolution of the lesions may be expected within months or a few years. The spontaneous regression without any treatment is an additional diagnostic criterion. Idiopathic eruptive macular pigmentation: report of 10 cases The macular hyperpigmentation of melasma is commonly tan to brown. Blue or black may be evident in patients with dermal melasma. The distribution is one of three patterns Background. A new infancy-onset facial hyperpigmentation has been recently described. The etiology is still unknown, but the histopathological findings suggest a new form of acquired dermal macular pigmentation (ADMP) of unknown etiology. Methods. We performed a retrospective observational descriptive study among children tended in the Dermatology Department at Hospital Universitario de.
Neonates have rashes of all shapes and sizes. It's important for us to be able to reassure parents where appropriate. This two part series deals with neonatal dermatology. In Part 1, we look at the benign conditions, and in Part 2 we will look at the more sinister ones. In all the following skin conditions, the baby is systemically well One hundred and twenty-four acquired macular pigmentation cases were gathered from the electronic records; 21 were excluded due to history consistent with pigmented contact dermatitis (n = 3), lichenoid drug eruption (n = 12), and PIH (n = 6).Three patients with photographs suggestive of hyperpigmentation from other causes, including idiopathic eruptive macular pigmentation (IEMP), urticarial.

following lichen planus) or in the epidermis (e .g . following acne or atopic dermatitis) • Epidermal hyperpigmentation fades more readily than dermal hyperpigmentation 33. PIH Individuals with darkly pigmented skin tend to have a greater frequency, severity and duration of PIH than those with lighter complexions , In the Indian context, common causes of facial melanosis include melasma, Riehl's Melanosis, Lichen planus pigmentosus, facial acanthosis nigricans, pigmentary demarcation lines, postinflammatory hyperpigmentation, and as the present observation indicates friction. Friction melanosis is an acquired pigmentary disorder due to habit of rubbing
Nevus of Ota is a form of dermal melanocytosis that produces hyperpigmentation of the eye and the surrounding adnexa along the V1/V2 trigeminal nerve distribution. The hyperpigmentation is seen as a bluish or brownish pigmentation of the eyes and/or on the face's skin and lids. On histopathology, excessive dendritic melanocytes can be found. That includes melasma, postinflammatory hyperpigmentation, acquired dermal macular hyperpigmentations, acanthosis nigricans, Addison's disease, drug induced hyperpigmentations, solar lentigines, phytophotodermatitis, periorbital and other hyperpigmentations. Factors such as skin phototype, gender and ethnicity might affect the efficacy of. Postinflammatory hyperpigmentation (PIH) is a reactive hypermelanosis that develops following cutaneous inflammation. Common causes of PIH include intrinsic skin conditions (e.g., acne and eczema) as well as external insults to the skin, such as burn injuries and dermatologic procedures. PIH more commonly occurs in individuals with darker skin, for whom it is often a source of significant.
Ashy dermatosis, first described by Ramirez in 1957 , is an idiopathic acquired macular hyperpigmentation disorder. The descriptive term ashy or los cenicientos was used because of the ashy blue-grey color of the lesions Hydrogen breath tests help to diagnose either intolerance to sugars or small intestinal bacterial overgrowth (SIBO) [seen in pts with altered small bowel motility- uncontrolled DM, chronic opiate use] abd pain, lethargy, N, anorexia, malaise. Chronic hep B carrier, febrile, hepatomeg, inc LFTs, + Hep D Ag It is an acquired pigmentary disorder that presents as asymptomatic light brown patches interspersed with hypopigmented macules [ 1 ] . Histology shows poikilo-dermatous tissue with hyperpigmentation of the basal layer, solar elastosis, and superficial telangectases [ 1 , 2 ] Drug-induced hyperpigmentation is a side effect of several medications. One of these medications, hydroxyurea, has been largely implicated in the hyperpigmentation of nail beds and oral mucosa.3 Here we describe a case of a woman in whom hydroxyurea treatment resulted in the development of widespread blue-gray macules resembling ashy dermatosis. During sun exposure, physiological reactions occur, triggered by a network of cellular interactions between keratinocytes, mast cells, fibroblasts, the dermal vasculature over melanocytes and dermal inflammation, playing an important role in the hyperpigmentation and reactivation of melasma lesions. 12 12.

Melasma (or chloasma) is a common acquired pigmentary disorder of the skin that leads to hyperpigmentation.It is more common in women. It appears as irregular, dark macules or patches, varying from brown to gray colors, arranged in a confluent or in a punctuate arrangement.It is seen mostly on the face and less commonly on other sun-exposed body sites Disorders of pigmentation 1. DISORDERS OF PIGMENTATION Dr. Angelo Smith M.D WHPL 2. SKIN COLOR Determined by - melanin - haemoglobin - carotenoids Melanin - major determinant Melanin is synthesized by melanocytes within melanosomes and transferred to keratinocytes Constitutive skin colour - genetically determined Facultative skin colour - induced by sun and hormone For the clinician encountering acquired melanocytic skin lesions, the potential for existence or development of invasive melanoma must always be considered. The spectrum of melanocytic lesions ranges from senile lentigo with no atypia to melanocytic hyperplasia and mild-severe atypia to lentigo maligna, which features malignant cells confined.

Int J Dermatol 2017; 56(12):1395-9. doi: 10.1111/ijd.13782 Acanthosis nigricans is a medical sign characterised by brown-to-black, poorly defined, velvety hyperpigmentation of the skin.It is usually found in body folds, such as the posterior and lateral folds of the neck, the armpits, groin, navel, forehead and other areas. It is associated with endocrine dysfunction, especially insulin resistance and hyperinsulinaemia, as seen in diabetes mellitus
They are used for treatment, diagnosis and prevention of illnesses.  Damaged basement membrane allowing falling of melanin and subsequent phagocytosis by dermal macrophages. leaving macular reticulated hyperpigmentation This laser fragments the laser beam into smaller pixels that can offer a deeper and more effective treatment without the burning and minimum downtime. Fractional lasers are costly: a treatment will cost $1,000 and up, and you will probably need 3-4 sessions over 3-6 months. The Fraxel system (brand name for one of the first fractional lasers. . It occurs most commonly unilaterally
pigmented lichen planus, idiopathic eruptive macular pigmentation, postinflammatory hyperpigmentation and Addison disease. Pigmented lichen planus is the main considered differential diagnosis of EDP. Lesions are usually characterized by bright violaceus-purple, flat, solid papules and often crossed by whitish lines (called as Wickham striae) Macular variant: jentigo pattern (lentiginous pattern plus nests of melanocytes at dermal epidermal junction) in the darker speckles and by some nests of melanocytes at the dermoepidermal junction at the tips of the papillae but background pigmentation has microscopic features of lentigo; tan-brown background with dark flat speckles in. Acquired symmetric melanosis that typically develops on sun exposed areas of skin & frequently on face. Forehead , cheeks , upperlips & chin are most commonly affected areas. Melasma has been used to describe any form of generalised facial hyperpigmentation including those related to post inflammatory changes & medication use . 8 Some investigators have reported that combination therapy using hydro-quinone, tretinoin, and topical steroids works better than monotherapy for the treatment of melasma. 9,10 Deep chemical peels and. Cutaneous hyperpigmentation is frequently observed in patients infected with the human immunodeficiency virus (HIV), particularly in the late stage of the acquired immunodeficiency syndrome (AIDS). However, these pigmentary changes are only rarely reported, probably because there could be many causes
Genital melanotic macules can exist as isolated lesions or be associated with a spectrum of syndromes. Lagier-Hunziker syndrome (LHS) is an acquired and benign disorder characterized by macular hyperpigmentation of the oral and genital mucosa; around half of such cases are associated with longitudinal melanonychia We have not attempted to discuss treatment modalities in detail. AB - Ashy dermatosis (AD), lichen planus pigmentosus (LPP), erythema dyschromicum perstans (EDP), and idiopathic eruptive macular pigmentation are several acquired macular hyperpigmentation disorders of uncertain etiology described in literature
