BACKGROUND: Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis.
CASE REPORT: A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC.
CONCLUSIONS: UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case.
