Abstract:
A 50-year-old white man with oculo(dermal) melanocytosis and longstanding iris nevus was found to have growth of the iris mass. Excision and histopathologic examination revealed a mixed cell type malignant melanoma. Benign nevus cells were present at the periphery of the tumor surrounding the entire melanoma. White patients with oculo(dermal) melanocytosis have a predisposition to uveal melanoma, which is usually choroidal in origin. Literature review showed only three confirmed cases of iris melanoma in this setting. Two additional cases initially published as spindle A melanoma have been reclassified as iris nevi based on the modified Callender classification of uveal melanomas. It is recommended that patients with oculo(dermal) melanocytosis be followed for the occurrence of uveal melanoma.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
