title: Unusual lesions and their management.
abstract: Treatment of a breast lesion should never be undertaken without a precise histologic diagnosis, which means careful examination of multiple sections of tissue embedded in paraffin and appropriately stained. The author described the clinical and histologic features of lobular and medullary cancers; cystosarcoma phylloides; carcinosarcoma; Paget's disease; adenoid cystic carcinoma; mucinous, tubular, and papillary cancers; and other unusual lesions that can originate elsewhere in the body. For each, treatment suggestions are offered.
