Neurilemmomas are benign tumors of peripheral nerve sheath Schwann cells. One of the variants of neurilemmoma is the ancient type of neurilemmoma characterized by degenerative features such as cystic degeneration, calcification, hemorrhage and hyalinization which could be easily misdiagnosed. Their occurrence in oral cavity is extremely rare and intraosseous type occurring in maxilla is exceedingly rare with very few cases being published in literature. A 38 year old male patient reported with a chief complaint of swelling over the left cheek and left upper back region since 10 months. The case is of recurrent intraosseous ancient neurilemmoma in the maxilla in the patient which is distinctive for the lesion. This unique case presented with distinct histologic architectural pattern of ancient neurilemmoma showing degenerative changes such as cystic degeneration and recurred within a short duration of time.
