title: Pseudopapillary Granulosa Cell Tumor: A Case of This Rare Subtype.
abstract: Background The pseudopapillary pattern of granulosa cell tumor is rare. Case We describe the case of a 35-year-old woman who presented with an initial diagnosis of papillary serous cystadenocarcinoma. Results Evaluation, including immunohistochemistry, led to the diagnosis of pseudopapillary granulosa cell tumor. Conclusion The pseudopapillary pattern of granulosa cell tumor is rare and must be suspected in order to utilize appropriate immunohistochemistry and reach the correct diagnosis. Inhibin positivity is particularly helpful.
