A 49-year-old man presented with a 4-year history of human immunodeficiency virus (HIV). He had not had any acquired immunodeficiency syndrome–defining condition, nor had he ever been hospitalized. His most recent CD4 cell count, which had been determined in February 1995, was 0.14×109/L (142/µL). His medical history was otherwise unremarkable except for mild facial seborrheic dermatitis and biopsy-proven molluscum contagiosum, both of which were easily controlled. He presented in June 1995 with a left forearm nodule that had progressively enlarged from apparently normal skin over a 2-week period. There had been no trauma. He had no systemic complaints.
