Thymomas with ring calcifications are very rare and quaint style. Herein, we presented our three cases of thymomas with ring calcifications and reviewed totally 10 cases including 7 cases of previous English literatures. The median age was 53 years. Myasthenia gravis was a complication in 40%. The median maximal diameter was 50 mm. They were diagnosed as pathological type B or had type B component. Based on World Health Organization (WHO) classification, 20%, 60%, and 20% cases were stage I, stage II, and stage III, respectively. Seven ring calcifications were within tumors (inner type) and two cases were outside tumors (outer type). The other had a thymoma arising in the calcic wall of a calcified thymic cyst (miscellaneous type). Four other anterior mediastinal tumors with ring calcification had been reported. We need pathological examinations for a definitive diagnosis. Surgeons should plan surgery because of the possibility of invasive thymomas, or other malignant tumors.

Luteinized thecoma associated with sclerosing peritonitis is a rare and enigmatic condition for which there is no standard treatment strategy. We report a case of luteinized thecoma associated with sclerosing peritonitis in a 31-year-old woman with a history of bipolar disorder. The patient presented with abdominal distension, and imaging examinations revealed bilateral ovarian tumors with ascites and pleural effusion. A diagnostic laparotomy was performed and showed bilateral ovarian tumors with polypoid surface contours, yellow watery ascites, and diffusely indurated omentum. Left salpingo-oophorectomy followed by right salpingo-oophorectomy and omentectomy were performed. Twenty-one days after surgery, the patient developed an intestinal obstruction resistant to conservative treatment. Gonadotropin-releasing hormone agonist and tamoxifen were administered to gradually improve the obstructive symptoms. After 18 months of follow-up, she is asymptomatic. Luteinized thecoma associated with sclerosing peritonitis may be a non-neoplastic condition that responds well to medical therapy.
