We report the case of a 75-year-old woman with a 15-year history of inappetance resulting in weight loss of approximately 40 kg. On physical examination, the skin of the lower extremities was markedly hyperpigmented with a brown-greyish hue. In addition, the skin of the legs was infiltrated, erythematous, riddled with erosions and necrotic ulcers. Clinical and laboratory evaluation revealed sicca syndrome, a pronounced polyclonal hypergammaglobulinemia (60 g/l), high levels of antinuclear, anti-SSA and anti-SSB antibodies. Histological examination of involved skin demonstrated a leukocytoclastic vasculitis.
