Disorders of Pigmentation

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, 2010
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.

The nature of pigment in pigmented apocrine hidrocystoma

Journal of Cutaneous Pathology, 1985
Apocrine 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, 1954
Abstract 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.
