A 38-year-old man presented with a 2-year history of painful nodules on his left shoulder. The first lesion developed at the base of his neck, and subsequent nodules appeared progressively toward the apex of the left shoulder. The nodules grew slowly and became both tender and spontaneously painful. There was no history of trauma or exposure to radiation, nor was there a family history of similar complaints. The patient was otherwise healthy, except for poorly controlled hypertension. Physical examination showed six 1- to 2-cm discrete, tender, firm nodules that were palpable in a linear distribution on the left shoulder (Figure 1). A skin biopsy specimen was obtained (Figure 2 and Figure 3).
