The nature of pigment in pigmented apocrine hidrocystoma
Journal of Cutaneous Pathology, 1985Apocrine hidrocystomas are often pigmented clinically. The cause of this pigmentation is not known. A case of pigmented apocrine hidrocystoma is presented with evidence of melanin as the underlying mechanism of the pigmentation. Review of an additional 150 cases suggests that this is rare.

The physiology of pigmentation
Oral Surgery, Oral Medicine, Oral Pathology, 1954Abstract 1. 1. The mature pigment-producing cell, the melanocyte, is derived from a short-lived embryonic structure, the neural crest. 2. 2. Valuable information on the inheritance of pigmentation has been derived from mice, fowl, fishes, and the fruit fly, Drosophila. A given gene affects a given aspect of the pigmentation process. 3. 3.

RESEARCH on the biochemistry of melanogenesis can be divided historically into three periods. 1 1. The identification of tryosinase, in 1895, by Bertrand and Bourquelot in certain varieties of mushrooms. 2. The demonstration of "dopa oxidase" in human skin, in 1917, by Bruno Bloch and the elicitation of some of the chemical steps in the conversion ...

SummarySkin color is highly individual and the variations are controlled by numerous genes. The different skin colors result from the size and number of melanosomes and do not mirror the amount of melanocytes. Disorders of pigmentation can result from migration abnormalities of melanocytes from the neural crest to the skin during embryogenesis.
