BACKGROUND: The incidence of extrapulmonary tuberculosis is higher in dialysis than general population. The aim of the study was to characterize clinical picture in dialysis patients, who developed extrapulmonary tuberculosis. METHODS: We retrospectively investigated the hemodialysis patients with extrapulmonary tuberculosis. 2208 hemodialysis patients were reviewed for extrapulmonary tuberculosis from October 1986 to January 2001. RESULTS: Seventeen patients (10 male, 7 female) were enrolled. The mean age was 57.4 +/- 12.4 years. The sites for extrapulmonary tuberculosis were peritoneum (35.3%, 6/17), cervical lymph node (17.6%. 3/17), bone marrow (5.9%, 1/17), spine (5.9%, 1/17), knee (5.9%, 1/17), brain (5.9%, 1/17), pericardium (5.9%, 1/17), cutaneous tissue (5.9%, 1/17) and genitourinary system (5.9%, 1/17). Fourteen of 15 tissue-biopsy specimens from suspicious sites revealed granulomatous inflammation. There were low yield in mycobacteria culture (11.1%, 1/9) and PCR (33.3%, 2/6). Three patients died during the treatment of the disease. CONCLUSION: Extrapulmonary tuberculosis constitutes a major part of tuberculosis in dialysis patients. Tissue biopsy with invasive procedures, such as laparoscopy or laparotomy, may be necessary if clinical presentations are suspicious.
