Mycobacterium avium complex infection.

We report the case of a 30-year-old woman with a three-year history of papules, nodules, and multiple ulcers of the left lower extremity. A skin biopsy specimen showed dermal fibrosis and patchy granulomatous inflammation in the upper-to-mid dermis that was associated with a perivascular, lymphohistiocytic infiltrate along with granulomas and necrosis in the subcutaneous fat. Tissue culture showed Mycobacterium avium complex infection. Clinical manifestations of cutaneous nontuberculous mycobacterial infections are discussed as well as their potential association with pedicures.
