Pigmented Nodular Basal Cell Carcinoma from a Congenital Melanocytic Nevus in a 68-year old female

Angela E. Sison MD, Joanne Kate M. Martinez MD, Karla Phoebe B. Castaños MD

Basal cell carcinoma (BCC) is the most common skin malignancy seen in sun-exposed areas. Pigmented nodular basal cell carcinoma (PBCC) is a clinical and histologic variant of BCC. Aside from displaying features seen in nodular BCC, it also contains increased brown or black pigment, the presence of which makes it necessary to rule out melanoma. Congenital melanocytic nevi (CMN), on the other hand, are common skin lesions that carry a risk of malignant transformation, especially melanoma.

Elisabeth Ryan, MD, Marie Claudine Francesca B. Perlas, MD, Johannes F. Dayrit, MD, FPDS

Basal Cell Carcinoma (BCC) is the most frequent skin malignancy of all cases of non-melanoma skin cancer. Diagnosis is through clinical and histopathologic confirmation.
