Granulomatous Mastitis Due to Mycobacterium Abcessus

Granulomatous mastitis is a rare, benign , chronic inflammatory condition of the breast. Clinical and radiogical features may mimic breast carcinoma. It represents a therapeutic dilemma and treatment alternatives are still unclear. Generally high recurrence rates are reported after excision. Granulomatous mastitis is a disease of unknow etiology; the most favorable factor is autoimmune reaction. Atypical mycobacteria are a rare cause of granulomatous mastitis especially in immunosuppression patients. We present a 27 –yearold female patient with a large painful breast mass without any predisposing local factors or immunosuppression. The conducted examinations revealed granulomatous mastitis due to Mycobacterium abscessus. Drainage and antibiotic therapy effectively enabled the cure and no recurrence is detected. Our reported case may be the first patient with spontaneus mastitis due to M. abscessus in the absence of any predispozing factors. We herein present the diagnostic and therapeutic aspects.
