Clear cell acanthoma (CCA)-like lesions of the nipple/areola: A clinicopathological study of 12 cases supporting a nonneoplastic eczematous disease.

Background: Clear cell acanthoma (CCA) of the nipple/areola has been reported. The CCA-like histology more likely represents a feature of eczematous dermatitis of the nipple/areola.

Objective: We reviewed cases of CCA-like lesions of the nipple/areola and compared them with classic CCA to clarify their relationship.
