Cutis. 2018 May;101(5):362, 365-366

A 76-year-old man presented to the dermatology clinic for an annual total-body skin examination as well as evaluation of a new submental skin lesion. His medical history included successfully treated malignant melanoma in situ, multiple actinic keratoses, and an eccrine carcinoma. During the examination, a 1-cm pinkish red plaque was found on the skin in the left perianal region. The patient was unaware of the lesion and did not report any symptoms upon questioning.
