Unusual Eczematous Dermatitis on the Nipple and Areola in a Young Man with Clear Cell Acanthoma.

A 24-year-old man with no personal or family history of atopic dermatitis or psoriasis consulted our dermatology department with a desquamating reddish lesion on the left areola and nipple. The lesion, which had developed during the past 4 months, bled occasionally and was treated initially as dermatitis with a combination of topical corticoids and antimicrobials, resulting in partial lessening of the condition. An ultrasound of the skin revealed increased blood flow within the nipple thickening of the dermis. During physical examination, we observed a well-defined desquamating plaque with a slightly shiny surface on the left nipple and areola (Figure 1).
