Only nonspecific cutaneous involvement has been reported to date. A 69- year-old Spanish woman with chronic myelogenous leukaemia deve loped fever and two subcutaneous nodules. The patient complained of extreme pain . Biopsy revealed a granulomatous lobular panniculitis with a characteristic ‘ fibrin ring’ or ‘ doughnut’ appearance: fibrin and inflammatory cells arran ged around a central clear space. Changes of membranous lipodystrophy were also found. Q fever serological studies were positive. Our patient had panniculitis w ith singular histopathological features. These histopathological changes have be en described in liver and bone marrow of patients with Q fever.
