An atypical dermoscopic presentation of malignant melanoma

A 78-year-old Caucasian man presented with a 5 mm pink and black papule on his right back. The patient was receiving treatment for squamous cell carcinoma of the tongue and had previously received treatment for basal cell carcinoma. The patient was unaware of the lesion until it was identified by his oncology team, and he denied any associated symptoms. The remainder of the TBSE was unremarkable. Dermoscopic exam revealed central yellow-orange and black clods and small, gray dots which were encircled by a pigmented black-blue annulus.
