“…Histopathologically, AS shows degenerative features such as hemorrhage, hemosiderin pigmentation, cellular atypia, and areas of myxoid degeneration. [ 7 ] In the present case also, all the histological features were noted accompanied by Antoni A and B cellular configuration with verocay bodies. Immunohistochemically, they are positive for S-100, Leu-7, and Myelin basic protein confirming their neural origin.…”

Oral schwannomas (OSs) are rare benign tumors of oral cavity derived from peripheral nerve sheath, composed of proliferation of schwann cells in a characteristic pattern. AS are long-standing lesions which exhibit degenerative changes and atypia due to which they could be mistaken for malignancy. The mean age of occurrence of AS in oral cavity is 43 years, and no case of oral AS has been reported in a pediatric patient so far. Here, we present a rare case of AS of oral cavity in a 10-year-old male child.

Neurilemmoma, neurinoma or schwannoma is a benign tumor of neurogenic origin, arising from the myelin sheath of a neuron. Head and neck region accounts for 25%–48% of these tumors reported till date. On the contrary, intraoral sites form only 1% of the cases accounted. Although a few cases of intraoral neurilemoma of mental nerve has been reported in English literature, none has been reported to arise from the terminal fibers of the mental nerve. In this particular article, we present a case were the tumor was noted in the lower labial mucosa.

“…Schwannomas most often occur in the fourth and fifth decade of life and seem to have a 1.6:1 female predilection. 6 They have been found to be present in such varied locations as the brachial plexus and the sciatic nerve. Rarely, Schwannomas can be found in the leg or in the foot and ankle region.…”

INTRODUCTIONSchwannomas are benign, encapsulated, slow-growing and usually solitary tumors originating from Schwann cells of the peripheral nerve sheath. Schwannomas of the superficial peroneal nerves are very rare, and therefore scarcely documented in the literature. The authors report a case of a diagnosed superficial fibular nerve sheath tumor with an unreported clinical presentation.PRESENTATION OF CASEA 52-year-old Caucasian female arrived to our Orthopedics Department complaining of pain and numbness of the lateral aspect of her left leg. These symptoms were present for a year and were more evident at the end of the day, or after a long time in the orthostatic position. No evidence of other medical illnesses was found. There was no record of prior traumatic events related to that limb. Diagnosis of a benign peripheral nerve tumor was achieved and the patient was treated by surgical excision of the lesion.DISCUSSIONThe intermittent symptomatology presentation on this case suggest a mechanical compression etiology, allied to classical pain and paresthesia often exhibited by this kind of the tumor. An intracompartimental pressure elevation could explain why the symptoms disclosed an episodic pattern, due to a constricted, inclosed nerve.CONCLUSIONWe describe a rare case of a patient with an unusual superficial peroneal nerve Schwannoma clinical presentation. Literature on this topic is scarce and, therefore, this case report intends to add further data about this kind of lesion.
