A 57-year-old white woman presented with a 2-year history of an intermittently bleeding growth of her left nipple. She had no history of internal malignant disease. Findings from physical examination revealed a 1.2 × 1.1-cm eroded patch confined to approximately 60% of the left nipple (Figure 1). There was no lymphadenopathy of the regional lymph nodes. Following an initial diagnostic biopsy, the lesion was completely excised with 2 stages of Mohs micrographic surgery, and the remaining portions of the nipple were reconstructed with a complex wound repair. Sections from the excisional specimen are seen in Figure 2 and Figure 3. An immunoperoxidase stain for smooth muscle actin was also performed on this tissue.
