Becker's nevus with ipsilateral breast hypoplasia: a case report and review of literature

Specific cutaneous associations in patients with Becker's nevus have been reported. We present a patient with typical clinical and histopathological features clearly consistent with Becker's nevus associated with ipsilateral breast hypoplasia. The changes were distinct and could be separated from smooth muscle hamartoma. We include clinical and histological illustrations of our case.
