The melanocyte and melanoma

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.

Congenital Melanocytic Nevi

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, 2004
Distinction 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

Expression patterns of S100 proteins in melanocytes and melanocytic lesions

Melanoma Research, 2009
S100 proteins are differentially expressed in tumours of epithelial origin. Little is known about their expression in melanocyte-derived tumours of neuroectodermal origin. We have analysed the expression of some S100 proteins in this line of lesions using SAGE Genie informatics, cell culture and human tumour tissue.

Epithelial, non-melanocytic and melanocytic proliferations of the ocular surface

Seminars in Diagnostic Pathology, 2016
Ocular surface tumors are commonly encountered by ophthalmologists and ophthalmic pathologists. These tumors have varied clinical manifestations. In this article, we discuss the most commonly encountered non-melanocytic and melanocytic ocular surface tumors, with emphasis on their common clinical features, morphologic patterns, and prognostic factors.

Myoepithelioma with melanocytic colonization (melanocytic myoepithelioma): a case report

Journal of Cutaneous Pathology, 2009
Mixed tumors of the salivary glands and the skin (also known as chondroid syringomas) contain epithelial and myoepithelial components in a chondroid to myxoid stroma. Lesions that are composed solely of cells with myoepithelial differentiation are known as myoepitheliomas.

Melanocyte-Stimulating Hormone: A Regulator of Human Melanocyte Physiology

Pathobiology, 2008
Although the melanocyte-stimulating hormone (MSH) is well-recognised as a pigmentary hormone in animals, its role in human pigmentation is still a matter for conjecture, not least because cultured human melanocytes have proved to be relatively refractory to the peptide.
