Hematoxylin-eosin–stained sections of the tissue specimen showed hyperkeratosis and acanthosis, with no evidence of infection or neoplasia. Gram and acid-fast bacillus stains and fungal cultures of the exudate were negative for organisms. Culture of the tissue yielded slow-growing, golden-yellow, atypical mycobacteria that were positive for acid-fast bacilli. Acid-fast bacillus stains and fungal cultures of bone marrow and blood samples were negative for organisms. Chest x-ray films revealed new scarring in the right upper lobe, which might have been the source of the mycobacteria or the result of radiation therapy or pneumonia.
