A case of primary ovarian atypical carcinoid tumor was reported. The patient was admitted to the clinic on the basis of an increase in abdominal circumference for 2 years and discovery of a huge pelvic mass on the third day of treatment, and the pelvic magnetic resonance imaging (MRI) showed a huge cystic solid abnormally enhancing mass in the abdomen and pelvis cavities, and abnormally reinforcing nodules in the liver and right retroperitoneum as well as a soft tissue mass, so she was treated with a comprehensive staging operation for malignant tumor of the ovary and a biopsy of the surface of liver, and was diagnosed as ovarian atypical carcinoid tumor at stage Ⅳ(G₂T_3cN_1bM_1b ) based on the results of the postoperative examination combined with liver metastasis and retroperitoneal metastasis, 6 cycles of postoperative chemotherapy, recurrence more than 1 year after surgery.
