Introduction Schwannomas are benign tumors originating from differentiated Schwann cells. Being the least common intraoral neoplasm of neural origin, it is rarely seen in the palate. The literature lacks an extensive review of intraoral schwannoma confined to the palate. Objective To review previously reported cases of palatal schwannoma along with an illustrative case, and to provide a better insight regarding clinicopathological and radiological features of this neural tumor in a rare intraoral site. Data Synthesis We present a case of palatal schwannoma in a 16-year-old female. An additional 45 cases were identified in 2 medical database searches (PubMed and Google Scholar) published from the year 1985 onwards, and from 13 countries, in the 5 continents. The ages of the patients ranged from 3 to 84 years old. Palatal schwannoma showed a slight predilection to females, with a male/female ratio of ∼ 1:1.81. Hard palate involvement is almost twice greater than soft palate involvement. Surgical excision was employed in almost all of the cases, and recurrence was reported only once. Conclusion Palatal schwannomas, although rare, have been reported both over the hard and the soft palate. They mostly present as a painless, firm, well-encapsulated, slow-growing solitary lesion over the lateral palatal aspect.Imaging can add to suspicion and can delineate a differential diagnosis, but the diagnosis is confirmed by pathological examination. Fine-needle aspiration cytology (FNAC) is almost always inconclusive. Immunohistochemistry can assist in confirming a diagnosis, but is more important to rule out close differentials. Complete surgical excision is the treatment of choice, and recurrence or malignant transformation are extremely rare.

“…To reconstruct defects of the soft palate, different strategies are mentioned and described in the literature and should address the rehabilitation of functional aspects concerning speech, swallowing and airway. Small defects can be covered by transoral approaches with a cranially pedicled ipsilateral tonsil-flap [ 17 ], a free buccal mucosal graft (FBMG) [ 10 ], buccal mucosal flap (BMF), or a buccinator flap (BMMF) with or without containing the facial artery [ 10 ]. Larger defects of the soft palate can make a free flap reconstruction necessary.…”

“…However, 1–12% of schwannomas affect the intraoral area, most frequently the tongue or mouth floor followed by palate, gingiva, vestibule and lips [ 9 ]. Appearance on the soft or hard palate is classified as not commonly seen [ 10 ]. The hard palate is more commonly affected, one-third of the palatinal lesions affect the soft palate [ 6 ].…”

Schwannomas are benign neurogenic neoplasm arise from the peripheral Schwann cells of the nerve sheaths. These tumors present as solitary and encapsulated lesions. Intraoral schwannoma is not commonly found in the palate and extremely rare at the junction of hard and soft palate. These benign lesions are slow-growing tumors with low potential for malignant transformation and need complete excision as treatment. As it has uncommon occurrence and nonspecific clinical presentations, the diagnosis is usually confirmed by histopathological examination and immunohistochemical evaluation. Here, we report a case of a large schwannoma at the junction of the hard and soft palate, which is an extremely rare location of this tumor.
