REPORT OF A CASE
A 38-year-old man complained of a discoloration on the left side of his neck that began as a small red spot 5 years previously. He stated that when he vigorously exercised the ''rash'' would spread to the other side of his face, neck, and shoulder, and would burn. He also described, on occasion, mild pruritus and a sensation of warmth. Treatment had consisted of hydrocortisone and desoximethasone creams without improvement.
