Granuloma annulare in a patient with malignant lymphoma

We describe the case of a 69-year-old man with malignant lymphoma who developed granuloma annulare on his fingers. The number of cutaneous nodules increased when a recurrence of lymphoma was demonstrated during the course of disease. Granulomatous lesions disappeared after the fifth cycle of chemotherapy with CHOP (cyclophosphamide, Adriamycin, vincristine, prednisolone). The coexistence of these two diseases is relatively rare. The clinical features seen in this case, however, might suggest that granuloma annulare is a generalized granulomatous reaction induced by malignant lymphoma.
