While the etiology of sarcoidosis remains uncertain, mycobacteria have been suggested as a causative infectious agent. To investigate the causal relationship between mycobacteria and sarcoidosis, we performed a reverse blot hybridization assay (REBA) to identify mycobacteria from the skin samples of nine patients with sarcoidosis. Six of the nine samples were shown to be positive for mycobacteria by REBA, including Mycobacterium tuberculosis and non-tuberculous mycobacteria. This is the first study to identify mycobacteria from the skin samples of sarcoidosis patients using REBA, and our results could strengthen the etiologic association between mycobacteria and sarcoidosis.
