血中CA-125が高値を示した結核性腹膜炎の1症例

抄録

There has been a marked decrease in the incidence of tuberculosis according to the development of antituberculous drugs and the propagation of BCG vaccination. Tuberculous peritonitis is therefore now a rare disease in Japan. We sometimes encounter difficulties in differentiating tuberculous peritonitis from other inflammatory disorders or ascites due to carcinomatous peritonitis.
Recently, we experienced a rare case of peritonitis tuberculosa. She had the exploratory laparotomy for her preoperative diagnosis of peritonitis carcinoma due to the high level of CA125 tumor marker and the findings of USG and CT scan, but her postoperative diagnosis resulted in peritonitis tuberculosa. Antituberculous therapy reduced her serum CA-125 titers to the normal range and improved her clinical symptoms.
This case suggests that CA-125 would be used as a therapeutic marker of chronic peritonitis as tuberculous peritonitis.
