Report of a Case.—  A 77-year-old woman was admitted to La Paz Hospital (Madrid) because of nodular cutaneous lesions on the abdomen and extremities, fever, asthenia, Fig 1.—Multiple nodular inflammatory lesions on thigh. Fig 2.—Granulomatous and abscessed inflammatory infiltration on the subcutaneous tissue (hematoxylin-eosin, ×10). anorexia, and a 10-kg weight loss in the last two months.
