Adult granulosa cell tumor with rare pulmonary presentation.

Adult granulosa cell tumor (GCT) is an uncommon sex cord-stromal neoplasm of the ovary. It typically demonstrates locoregional spread, and disease outside of the pelvis as metastasis is uncommon. Only a rare case of primary thoracic adult GCT has been documented, and here we describe another occurrence with unusual pulmonary presentation, thereby expanding the anatomic distribution across which adult GCT could potentially arise.
