Hyperpigmentation of the Right Side of the Face. Presented by Christopher M. Pappa, MD, and James T. Swift, MD.
The patient, a 13-year-old student, is a healthy young boy, with no family history of cancer, diabetes, tuberculosis, chronic skin disease, or family pigmentations. There have been no serious illnesses, no abnormalities, and no known allergies, or any medications. He was born with a large pigmented area on the right side of his face (Figure) that has been unchanged since birth and is asymptomatic. He was evaluated at the Hospital of the University of Pennsylvania in 1955 at which time a biopsy specimen was reported as "hyperpigmentation with no nevus cells." The lesion has never been treated.
A large hyperpigmented patch covers the right side of the face, right side of nose, and part of the forehead. A small hyperpigmented area is present behind the right ear.
