Dermatology Online Journal: 12 (4): 7
Abstract
A 22-year-old woman sought medical care for a lesion in the plantar region of her left foot, a well-formed nipple surrounded by areola and hair. Microscopic examination of the dermis showed hair follicles, eccrine glands, and sebaceous glands. Fat tissue was noted at the base of the lesion. Clinical and histopathologic findings were consistent with the diagnosis of supernumerary breast tissue, also known as pseudomamma. To our knowledge, this is the first report of supernumerary breast tissue on the foot.
