[A case of liposarcoma associated with chronic tuberculous empyema]

A case was 77-year-old male with left back pain who had received artificial pneumothorax therapy 40 years ago due to lung tuberculosis. He had a spindle shaped mass in his left chest wall which had connection to the chronic tuberculous cavity. Because malignant cell was not detected by biopsy, it was therapied as tuberculous abscess. Then the mass grew rapidly into 20 cm in diameter. Although surgical operation was carried out, it was impossible to remove it all. After the surgery, the pathological findings was liposarcoma. In spite of the radiotherapy, the patient died 4 months after the surgery. We should always keep in mind the early diagnosis of malignant tumor associated with chronic tuberculous empyema.
