The Quarterly Review of Biology, 1960
Melanocytes may be regarded as unicellular, pigment-secreting glands, largely though not entirely confined to the epidermis, of which they are a constant though often un-recognized cellular component. Their numerical incidence, and their branching form, with numerous dichotomizing processes, are such as to form a reticular system within the epidermis ...

Veterinary Dermatology, 2003
Abstract In veterinary medicine, our understanding of the biology and regulation of melanocytic function is mostly based on information realized from human and murine studies. Improved understanding of the biology of melanocytes is needed to develop more effective treatment regimens for malignant melanoma and other melanocytic disorders. In vertebrates,

Studies on Melanocytes: VI. Melanocytes in the Middle Ear
Archives of Otolaryngology - Head and Neck Surgery, 1982Melanocytes are present in the lamina propria of the middle ear mucosa of young children to elderly adults in both whites and blacks. Melanin pigment melanin pigment also is seen in the epithelial cells, so-called melanogenic metaplasia. The melanocytes in the middle ear mucosa are of neural crest origin and their presence explains melanocytic tumors ...

Non‐melanocytic mimics of melanocytic neoplasms
Histopathology, 2011Bhawan J (2012) Histopathology 60, 715–730 Non‐melanocytic mimics of melanocytic neoplasmsOn histopathologic examination, many non‐neoplastic conditions mimic benign or malignant neoplasms. Alternatively, some benign and malignant neoplasms can also mimic non‐neoplastic lesions. This is true of all organ systemsskin is no exception.

The Laryngoscope, 1990
AbstractThis paper reviewed some of the interesting biological aspects of melanocytes and their relationship to the nevus and to melanoma. It also proposed a rationale for “adequate” surgery in the management of melanoma according to level, depth, margins, and trends in treatment.

Melanocytic lesions and melanocyte populations in human epidermis
British Journal of Dermatology, 1991Basal melanocytes were counted and atypia assessed on an arbitrary scale in punch biopsies from the sun-exposed extensor aspect of the forearm of normal skin and from the covered skin of the buttock of patients with pigmented naevi and control subjects.

Clinics in Laboratory Medicine, 2009
This article reviews congenital melanocytic nevi (CMN), which are present at birth or appear shortly thereafter, and their main histologic features. Several histologic variants and histopathologic criteria that differentiate CMN from other nevi, such as atypical or dysplastic nevi, and from nevoid malignant melanoma, are discussed.

Non-melanocytic lesions mimicking melanocytic lesions
Pathology, 2004Distinction between benign and malignant melanocytic lesions commonly represents a big challenge for the pathologist. Equally difficult is separating tumours with melanocytic lineage from those displaying other lines of differentiation. This is because benign and malignant melanocytic lesions are able to display a wide range of histological appearances

Immunosuppression and melanocyte proliferation
Melanoma Research, 2009Melanocytes are pigmented cells derived from the neural crest; their proliferation is restrained by immune system. The eruption of nevi after an immunosuppressive condition is a peculiar phenomenon indicating that the immune system may play a major role in limiting proliferation of melanocytes.

Different types of melanocytic nevi do exist in relation to their epidemiology, evolution, morphology, genetics, and their associated melanoma risk. The introduction of dermoscopy has opened a new morphologic dimension of melanocytic nevi; this along with recent progresses in our understanding of the molecular pathways involved in the formation of nevi
