Two cases of tuberculous peritonitis and clinical significance of serum CA-125

We had recently experienced two cases of tuberculous peritonitis. One was suspected of ovarian cancer but finally diagnosed as tuberculosis by the exploratory laparotomy. The other was found out casually at the operation of benign ovarian tumor. Both cases accompanied with pulmonary tuberculosis. Tuberculous peritonitis should be considered in the differential diagnosis in patients with abdominal disorders. Remarkable elevation of serum CA-125 related to ovarian cancer was found in both cases. It was suggested that level of serum CA-125 might be useful for diagnosis and monitoring of the disease.
