A six-year-old female miniature pig was presented after a week-long episode of anorexia. A tumor was identified in the abdominal cavity by an X-ray examination. Surgical removal of the tumor was conducted on day seven after the initial examination. Because of the position and the histopathological findings of the tumor, the diagnosis was for a malignant granulosa cell tumor. After the operation, the case demonstrated no symptoms for approximately 200 days. On day 223 after the initial examination, the case study suddenly died after displaying neurological symptoms. At necropsy, a nodule was found in the pituitary gland. However, no recurrence of the tumor in the abdominal cavity was observed. Because the histopathological findings of the nodule were the same as those of the abdominal tumor and the tumor cells were κ-light chain-positive, plasmacytoma was the revised diagnosis of the tumor. Surgical removal of the tumor improved quality of life in the case study, and no symptoms were observed for approximately seven months. Therefore, we concluded that the surgical treatment resulted in a good prognosis for this case study.
