Nontuberculous mycobacteria (NTM) is commonly found in the surrounding
environment and can cause
opportunistic infection. Mainly, it causes
lymph node infection in the cervical area, which is often known to occur in
children. Recently, we have experienced a case of NTM
infection on a
branchial cleft cyst in a 36-year old
male. NTM was diagnosed by
fine needle aspiration and
branchial cleft cyst was confirmed by postoperative pathologic findings. We
report this case with a
review of
literature.
