A Case of Lupus Panniculitis Involving the Breast / 대한피부과학회지

Lupus panniculitis is a chronic inflammatory disease of subcutaneous fat that occurs in 2~3% of patients with systemic lupus erythematosus. Lupus panniculitis typically presents with firm, indurated subcutaneous nodules or plaques commonly developed in proximal extremities, trunk, head and neck. Breast involvement with lupus panniculitis (lupus mastitis) has been infrequently reported. We experienced a case of lupus mastitis developed in a 44-year-old female confirmed by histologic features and laboratory findings. Antimalarial therapy resulted in the complete resolution of the lesions.
