Acquired dermal melanocytosis of the face and extremities
Clinical and Experimental Dermatology, 2016Acquired dermal melanocytosis (ADM) is a relatively rare, but well-described disease among adolescent to middle-aged East Asian women, particularly those of Japanese and Chinese descent. Clinically, ADM manifests as multiple punctate and greyish-brown pigmented areas 1-3 mm in diameter occurring on both sides of the forehead and zygomatic region.

Acquired dermal melanocytosis restricted to the hand
European Journal of Dermatology, 2016The term “dermal melanocytosis” encompasses a group of pigmentary disorders associated with melanocytic proliferation. Acquired forms are uncommon; they have similar histological features with the congenital ones but show a puzzling clinical distribution, not corresponding to any of the existing forms [1]. Acquired dermal melanocytosis (ADM) reportedly

Congenital Segmental Dermal Melanocytosis in an Adult
Archives of Dermatology, 1992Dermal melanocytosis is characterized by the presence of melanocytes in the dermis. There are several morphologic forms, such as the blue nevus, the mongolian spot, the nevus of Ota, and the nevus of Ito. In this article, we report an unusual case of dermal melanocytosis.A 28-year-old white woman was referred to us, as she had an extensive, speckled ...

Induced Dermal Melanocytosis in Hairless Mice
Archives of Dermatology, 1962Dermal melanocytosis is a natural state for many mammals. In the human primate, it appears only as a congenital or atavistic remnant in nevus fuscocaeruleus ophthalmomaxillaris of Ota, the mongolian spot, and in the blue nevus. Its development has been thought due to arrested migration of pigment cells, and this condition has not been regularly ...

AbstractAcquired dermal melanocytosis (ADM) classically occurs on the face. However, extrafacial ADM including palmar ADM has been reported on rare occasions. We present the first report of ADM confined to the palm without ADM lesions in other regions in a 30‐year‐old Japanese woman. The patient presented with several interspersed macules up to 1 cm in

Generalized Dermal Melanocytosis
Archives of Dermatology, 1981• A female infant was born with generalized blue-gray discoloration of the skin. Light microscopy demonstrated the diffuse distribution of dihydroxyphenylalanine-positive, dermal melanocytes. Electron microscopy confirmed the identification of the pigment-bearing cells as melanocytes and demonstrated individual melanocytes to be invested with a ...
