| Abstract: | We report on a case of a granulosa cell tumor of the ovary metastatic to the lung and diagnosed by fine-needle aspiration. The patient was a 70-yr-old woman who was diagnosed with a granulosa cell tumor of the ovary 17 yr previously. She subsequently developed abdominal metastases and received several cycles of chemotherapy. A 0.5-cm right upper lobe pulmonary nodule was found on a routine chest radiograph and subsequent computerized tomography scan. Aspiration cytology of this pulmonary nodule demonstrated small, relatively uniform neoplastic cells with nuclear grooves and indentations consistent with a granulosa cell tumor. The differential diagnosis of granulosa cell tumors from other metastatic and pulmonary lesions is reviewed. Diagn. Cytopathol. 16:341–344, 1997. © 1997 Wiley-Liss, Inc. |
