Sarcoidosis Mimicking Cancer Metastasis Following Chemotherapy for Ovarian Cancer / Journal of the Korean Cancer Association, 대한암학회지

ABSTRACT

We report on a rare case of sarcoidosis that developed after chemotherapy for ovarian cancer, and mimicked a cancer metastasis. A 52-year-old female diagnosed with stage III ovarian cancer underwent curative surgery and postoperative chemotherapy. Four months later, her whole-body positron emission tomography and computed tomography (CT) scan showed high uptake in the mediastinal lymph nodes, and ovarian cancer recurrence was suspected. Biopsy of the mediastinal lymph nodes and subcutaneous nodules revealed noncaseating granulomas. These lesions resolved spontaneously without treatment; however, newly developed perilymphatic and centrilobular nodules were observed on follow-up chest CT. Surgical biopsy of these lesions also showed noncaseating granulomas. She was finally diagnosed with sarcoidosis.
