Tumors originated from peripheral nerve tissues are neurofibroma, neurilemoma, plexiform neurofibroma, malignant schwannoma, and granular cell tumor. Neurofibromas seem to occur in two forms : The first one is circumscribed solitary neurofibroma and the second group is neurofibromatosis or Von Recklinghausen's disease, which is a congenital and familial disease, presenting abnormalities of the skin, nerve system, bones and soft tissue. A solitary neurofibroma is a benign, relatively circumscribed, noncapsulated tumor which often presents in the skin and subcutaneous tissue as a soft sessile or pedunculated mass. It may occur anywhere in the head and neck, but the common site of the occurrence is the tongue, buccal mucosa, palate in frequency. Since solitary neurofibroma is a relatively radioresistant and its recurrence rate seem to be low, the treatment of choice is surgical excision. The author would like to present a case of unusually large solitary neurofibroma occured in the chin, which was successfully treated with surgical excision and reconstructed using deltopectoral flap and tongue flap.
