A case of ovarian sarcoidosis mimicking malignancy.

We present a case of systemic sarcoidosis with ovarian and peritoneal involvement. The atypical clinical presentation of the disease has lead to a problem of the differential diagnosis with ovarian cancer. A 72-year-old female was admitted because of low grade fever, fatigue and dilatation of the abdomen. Clinical and laboratory evaluation of the patient revealed moderate right pleural effusion, ascites, diffuse ovarian infiltration, presence of enlarged intraabdominal lymph nodes and a substantially high value of serum CA 125. Histological examination after laparotomy was indicative of ovarian sarcoidosis.
