Unusual form of cutaneous infiltration by cancer

Abstract

Breast cancer is the most common visceral neoplasm which metastatizes in skin. Skin infiltration by breast cancer may appear as various types of neoplastic/inflammatory lesions, including plaques, pigskinlike areas, scirrhous morphea-like lesions, nodules, zosteriform lesions, and papulovescicles. An unusual form of cutaneous infiltration involving a mammary region bearing a post-mastectomy surgical skin scar is herein described: interestingly, such a cutaneous cancer involvement could not be included in the above classification, because it merely consisted of red-purple areas dealing with small telangiectasias, without any sign of inflammation.
