BACKGROUND: Neurinomas or schwannomas are benign, encapsulated growing tumors of the Schwann cells of the nerve sheets; 25-45% are located in the head and neck region. They are found rarely in the oral cavity. Most of the intraoral schwannomas are located on the tongue. Other less common locations are the buccal mucosa, palate, floor of the mouth, gingiva and lips. The therapy of choice is complete surgical excision. CASE REPORT: An 11-year-old girl presented with a 3-month history of painless swelling of the hard palate. CT scan showed a right palatinal mass of 2 cm, reaching into the right maxillary sinus. After complete surgical excision the histological findings showed a neurinoma (Antoni type A). During a 2-year follow-up, there were no signs of recurrence. Because of the benign tumor type we considered the young patient to be healed.

Twenty patients with primary malignant melanoma of the oral cavity have been described. They formed 3.9 percent of the total number of patients with malignant neoplasms of the oral cavity. The upper gingiva was most commonly affected. In this series, there were 14 male patients and 6 female patients who ranged in age from 26 to 80 years (average 58 years). The first symptom of melanoma was hyperpigmentation of the mucosa in 10 patients, tumor in 7, and pain in 3 edentulous patients with prostheses. Radical surgery was performed in 13 patients, followed by chemotherapy and radiotherapy in 9 cases. Only 1 patient survived 9 years. The remaining 12 died 11 to 18 months after radical treatment. Palliative therapy was applied in three patients, two patients were treated symptomatically, and two patients refused treatment. Early detection of melanoma is an indication for radical treatment and may increase the survival rate of patients with this disease, which is still very low.

In this paper we report the reconstruction of a large defect of the hard palate by covering free iliac bone with a jejunal flap. The new palate is moist and tough but not bulky. This new method brings with it the useful concept that the jejunum might nourish the free bone through its serosa.
