A rare female genital tract tumor: Benign granular cell tumor of vulva: Case report and review of the literature

Abstract Background The granular cell tumor (GCT) of vulva is a rare female genital tract tumor. Case A 59-year-old female was incidentally noted to have a 1-cm sized lump in her left labium majus that subsequently increased in size to approximately 4 cm. The mass was totally excised under general anesthesia. Her postoperative follow-up was uneventful. Histologic examination of the tumor showed sheets and clusters of infiltrating tumor cells with morphologic features consistent with granular cell tumor. Conclusion Although benign and slow growing, it has a tendency for recurrence and can cause morbidity and mortality when presenting with multicentric or multiple organ involvement due to the lack of effective systemic therapy. Therefore, clinicians and pathologists should be aware of its clinical and histopathologic features.
