[A case of lung infection due to Mycobacterium abscessus (M. abscessus) complicated with primary macroamylasemia].
We report a case of lung infection due to Mycobacterium abscessus (M. abscessus), complicated with primary macroamylasemia. A 76-year-old man was admitted to our hospital in August 2002 because of bloody sputum and an abnormal shadow found on chest radiography. The patient had had pulmonary tuberculosis from 1998 to 2000. He was found to be antacid bacillus-positive (Gaffky 5) on examination of the sputum in August 2002, but after hospitalization was negative for tuberculosis bacillus on sputum examination by the PCR method. We had suspected the presence of non-tuberculous mycobacterial disease since the patient's admission, and had started a regime of three drugs: clarithromycin, rifampicin, and ethambutol. The bacteria were identified as M. abscessus in a later sputum culture examination. It was noticed that the blood amylase level was high, and the disease was diagnosed as primary macroamylasemia. Such a case of lung infection due to M. abscessus complicated with macroamylasemia has rarely been reported in Japan.
