[Mucosa-associated lymphoid tissue lymphoma of the lung].

Mucosa-associated lymphoid tissue (MALT) lymphoma of the lung is rare. We present a case of MALT lymphoma of the lung. A 64-year-old man was admitted to our hospital because of an abnormal shadow on chest X-ray. He was performed transbronchial lung biopsy (TBLB) in our hospital, but the results was not diagnostic. We performed surgical biopsy using thoracoscopy due to the possibility of malignancy. The pathological diagnosis was MALT lymphoma. He underwent an chemotherapy after the operation and has been followed up at an outpatient for 8 years.
