[Chlamydial infection with marked ascites that simulated ovarian cancer].

We describe a case of genital chlamydial infection with marked ascites and an adnexal mass that simulated a malignant neoplasm. Laparotomy was performed. Multiple adhesions between visceral and peritoneum, enlarged retroperitoneal nodes were found. The right ovary contained a cystic mass. Examination of the peritoneal biopsies and ascites showed chronic lymphofollicular inflammation and chlamydial infection was suggested as the aetiology. The patient was treated with antibiotics and discharged from hospital in well-being. At follow-up examination four weeks later the patient had no symptoms.
