[A case of pericostal tuberculosis occurred in a long period after thoracoplasty]

A 79-year-old man with past history of thoracoplasty due to pulmonary tuberculosis visited a general clinic complaining of left back pain and left axillary tumor. As the pus of tumor aspirated was positive for PCR-TB, the patient was diagnosed as pericostal tuberculosis and introduced to our hospital. At first, the operation was considered, but the patient had high risk for the operation because he was old and low body weight and the lesion of tuberculosis in his thorax was very extensive. Anti-tuberculous drugs were administrated and exclusion of pus by needle aspiration was repeated. After starting the treatment, the size of tumor had reduced guradually. Pericostal tuberculosis should be taken into consideration in case of pericostal mass with past history of tuberculosis, and the method of treatment should be decided with considering patient's condition.
