A 53-year-old man was referred in 1998 for a pruritic eruption on his central chest of 8 months' duration. He reported a sensation of bulging over his lower sternum. On examination, he had a sharply demarcated, indurated, erythematous plaque on the central chest (Figure 1) and bilateral axillary lymphadenopathy. A biopsy specimen showed a nonspecific dermal proliferation of vascular structures (CD34+) with pleomorphic and multinucleated histiocytes (CD68+) and myofibroblasts (Figure 2). Results of immunostaining for S100, factor XIIIA, keratin, estrogen receptor, and progesterone receptor were negative. Tissue cultures were negative.
