pigmented basal cell carcinoma
Wednesday 22 May 2013
Melanin pigment is usually formed in solid, micronodular, multifocal superficial or follicular variants.
Basal cell carcinomas of the usual type are also populated by some melanocytes.
Other pigmented phenomena in basal cell carcinomas are the colonization one by a melanoma in situ, the metastasis of a melanoma to one, and the presence of a combined melanoma and basal cell carcinoma.
