Ocular and Dermal Melanocytosis
Archives of Ophthalmology, 1956 Pigmented lesions involving ocular structures are always a source of concern until proved benign. We wish to call attention to a striking pigment change, involving the eye and eyelids, which is benign but which simulates malignant disease. Because there exists a confusion of names describing pigmentary abnormalities of the eye and surrounding ...

Acquired Dermal Melanocytosis on the Wrist
Journal of Dermatology, 1997AbstractA 50‐year‐old Japanese man had a blue‐black patch on the dorsum of his right wrist. Light and electron microscopic study of the lesion revealed dermal melanocytes containing mature melanosomes, predominantly in the upper dermis. This case was diagnosed as acquired dermal melanocytosis confined to the right wrist.

Dermal melanocytosis: A clinical spectrum
Australasian Journal of Dermatology, 1996 SUMMARYWhile most dermal melanocytoses are congenital or have an onset in early childhood, there is a group which is clearly acquired, with an onset in adult life. While the Mongolian spot typically disappears in childhood, other dermal melanocytoses persist for life. A brief review of the clinical spectrum of the dermal melanocytoses is undertaken and

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 ...

Induced Dermal Melanocytosis in Hairless Mice
Archives of Dermatology, 1962 Dermal 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 ...

Acquired Linear Dermal Melanocytosis
Archives of Dermatology, 1982 • 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 entities.

The Journal of Dermatology, 2015 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
