Atypical Presentation of Metastatic Clear Cell Carcinoma And The Diagnostic Challenge of Leg Pain: A Case Report

This is a case of a 66-year-old female with a past medical history of stage III clear cell ovarian carcinoma (CCOC), status post chemotherapy and radical hysterectomy, who was incidentally found to have a metastatic retroperitoneal mass ten years later during a workup for persistent and vague thigh pain. Her pain was initially treated conservatively, and she was told to follow up in 3 months after attempting conservative measures such as over-the-counter pain medications and physical therapy. Despite adhering to these recommendations, here pain persisted, and a subsequent MRI revealed an unresectable presacral mass that was consistent with metastatic recurrence of clear cell carcinoma, for which the patient agreed to proceed with recommended palliative radiation therapy.
