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.

Primary Care: Clinics in Office Practice
Disorders of pigmentation encompass a wide range of conditions categorized into hyperpigmentation, hypopigmentation, and depigmentation, each with distinct etiologies, clinical presentations, and implications. This article outlines the pathophysiology, clinical features, diagnostic approaches, and management strategies for these pigmentary disorders ...

British Journal of Dermatology, 1977
Pigmented neurofibroma is a rare tumour of the dermis. The clinical features and histology of a lesion occurring in a female of 69 years are described in this report. This entity was first described by Willis in 1959 in three patients with pigmented dermal tumours which showed a plexiform structure and the presence of pseudo-Meissnerian bodies.

Pigmented casts have been reported with variable frequency in scalp biopsies from alopecia areata, trichotillomania, chemotherapy-induced alopecia and postoperative (pressure induced) alopecia. Their presence and morphology in other scalp disorders has not been described.

Journal of Burn Care & Research, 2015
There is at least a temporary loss of skin pigmentation with all but first-degree burns. Commonly, pigment changes persist for months, and sometimes, permanent changes in skin color add to the ultimate change in appearance that commonly affects burn patients.
