Figure 2. Carcinoma erysipelatoides masquerading as an erysipelas infection of the left breast in a woman with invasive ductal breast cancer.

Distant (A) and closer (B) lateral view of the left breast in a woman with invasive ductal left breast carcinoma shows a painless erythematous patch above the areola (black oval) that appeared the following 12 weeks of paclitaxel and four cycles of 5-fluorouracil, epirubicin, and cyclophosphamide (FEC). The skin biopsy showed metastatic cancer cells--consistent with breast origin--in the dermal lymphatics. Her scheduled mastectomy was postponed, and she was treated with additional chemotherapy.
