Generalized granuloma annulare associated with granulomatous mycosis fungoides.

We describe a 68-year-old man with plaque stage mycosis fungoides (MF) for 8 years. He developed tumorous lesions of granulomatous MF (GrMF) and generalized granuloma annulare (GA) after a previously indolent clinical course. Since then, the clinical course was aggressive with involvement of the bone marrow and lymph nodes, and leukemic change occurred. Systemic chemotherapy was given, but the patient died 9 months later due to neutropenic fever and septic shock. GA in malignant lymphoma has been reported most frequently in association with Hodgkin's disease. To the best of our knowledge, GA associated with GrMF has never been reported in the English language literature. The prognostic significance of the association of granulomatous inflammation and malignancy is reviewed.
