Abstract
Small round cell tumors of the nasal vestibule are very uncommon tumors and encountered rarely in the late-adolescent and adult age group. The authors experienced a case of undifferentiated small round cell tumor of left nasal vestibule in a 19-year old male patient. Histopathologic findings showed a small cell with irregular oval shape nuclei. Immunohistochemical study showed undifferentiated small round cell carcinoma because of all negative stain except vimentin. The computed tomography (CT) scan of paranasal sinus and chest X-ray showed no evidence of invasion and regional metastasis. The patient received local resection and vestibuloplasty using a free composite graft of auricular cartilage and skin, and had no recurrence or complication. We report our case with a brief review of the literatures.
