Strumal carcinoid tumor of the ovary: A rare case report

RATIONALE: Strumal carcinoid tumor of the ovary (SCTO) is a very rare kind of ovarian tumor. The symptoms of SCTO are often nonspecific and misleading. Therefore, a full understanding of the characteristics, diagnosis, and treatment methods of SCTO is important. PATIENT CONCERNS: In this study, we report a 63-year-old woman with SCTO whose most obvious symptoms were abdominal distention and weight loss of 5 kg for about 1 month. DIAGNOSIS: Her carbohydrate antigen 125 (CA125) levels were higher than normal. Gynecologic sonography showed an 8.8 × 7.5 cm mass with mixed density and an irregular shape behind the uterus. Pathologic and immunohistologic examinations confirmed SCTO of the right ovary. INTERVENTIONS: The patient underwent complete surgical resection of the whole uterus, bilateral ovaries, and fallopian tubes. OUTCOMES: The patient recovered well with no obvious complications and was discharged on the 10th day postsurgery. LESSONS: Complete surgical resection is vital to treat SCTO. Postsurgical pathologic and immunohistologic examinations can confirm a diagnosis of SCTO.
