Granular cells tumor of the vulva: an exceptional entity.

Abstract Granular cells tumor (GCT) is a rare tumor that develops on skin and soft tissues. Only 1-2% of these tumors present malignant behavior. The authors report three cases of GCT and review the management of these tumors. The first case is a 73-year-old woman who was diagnosed with an atypical GCT. She was treated with local excision and then presented a local recurrence 21 months after the surgery. The other two cases are 60- and 58-year-old women diagnosed with a benign GCT. They were treated with single excision; both patients underwent second surgery due to margin affectation. Management of GCT is not clear nowadays. The careful selection of patients with poor prognostic factors is very important. Follow-up for early diagnosis of local recurrence and metastases of these tumors is of utmost importance.
