Skin Cancer
Telangiectasias and a pearly, rolled border in dark skin or in a pigmented tumor may be difficult to discern.[ncbi.nlm.nih.gov]
Melanoma is a malignant tumor that originates in melanocytes, the cells that produce the pigment melanin which colors our skin, hair and eyes.[theskincancercenter.org]
, with up to 60-75 percent of tumors arising on the palms, soles, mucous membranes and nail regions. 25 Basal cell carcinoma (BCC) is the most common cancer in Caucasians,[web.archive.org]
Basal Cell Carcinoma
Reflected-light microscopy is a non-invasive method for investigating skin tumors, which is used especially for early detection and diagnostic assessment of pigmented tumors[ims.uniklinik-freiburg.de]
The original tumors were not noted to be pigmented.[doi.org]
Tumor surface is glossy and translucent like a "gem". Sometimes basal cell carcinoma is pigmented, nodal or ulcer type.[gkklinika.com]
Iris Melanoma
A pigmented tumor measuring 3 1 mm was seen in the left eye in the inferonasal part of the iris and the anterior chamber angle, beginning in the ciliary body and iris root[jamanetwork.com]

A biopsy can be necessary to differentiate fibrous papules from benign adnexal tumors or basal cell carcinomas (BCCs) that sometimes closely resemble its "pearly" appearance[doi.org]
Histopathologically, a clear cell fibrous, hypercellular fibrous, inflammatory fibrous, pigmented fibrous, pleiomorphic fibrous papule and epithelioid variant can be distinguished[doi.org]
