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.

“…The size of the lesion varies from 0.5 to 4 cm in diameter [ 53 , 54 ]. Intraoral lesions are frequently located in the tongue followed by palate, floor of the mouth, buccal mucosa, gingivae, lips, and vestibular mucosa [ 55 ]. Schwannoma can occur as an intraosseous lesion, which accounts for 1% of all benign primary bony tumors [ 54 , 55 ].…”

“…Pain and paresthesia are not uncommon for intrabony tumors [ 10 ]. Schwannoma has been reported in the age range of 8 to 72 years with an average age of 34 years with a slight female predilection (female to male ratio of 1.6 : 1) [ 53 , 55 ]. Surgical excision is the treatment of choice and recurrence and malignant transformation are extremely rare [ 55 ].…”

Diagnosis of peripheral oral exophytic lesions might be quite challenging. This review article aimed to introduce a decision tree for oral exophytic lesions according to their clinical features. General search engines and specialized databases including PubMed, PubMed Central, Medline Plus, EBSCO, Science Direct, Scopus, Embase, and authenticated textbooks were used to find relevant topics by means of keywords such as “oral soft tissue lesion,” “oral tumor like lesion,” “oral mucosal enlargement,” and “oral exophytic lesion.” Related English-language articles published since 1988 to 2016 in both medical and dental journals were appraised. Upon compilation of data, peripheral oral exophytic lesions were categorized into two major groups according to their surface texture: smooth (mesenchymal or nonsquamous epithelium-originated) and rough (squamous epithelium-originated). Lesions with smooth surface were also categorized into three subgroups according to their general frequency: reactive hyperplastic lesions/inflammatory hyperplasia, salivary gland lesions (nonneoplastic and neoplastic), and mesenchymal lesions (benign and malignant neoplasms). In addition, lesions with rough surface were summarized in six more common lesions. In total, 29 entities were organized in the form of a decision tree in order to help clinicians establish a logical diagnosis by a stepwise progression method.

“…Because this tumor is uncommon in the lips, a diagnosis of lip schwannoma is sometimes ignored until it has progressed to more advanced stages of growth and cosmetic disfigurement [9,13]. Because of the delicate neuronal anatomy within the vast neuronal innervation of the lips, surgical removal of schwannomas in the lips is intrinsically difficult, depending on the size and exact location of the lesion, and even minor injury during excision can result in considerable morbidities such as impaired speech, dysarthria, aspiration, paresthesia, and dysphagia [14][15][16]. Due to the sheer rarity of this neoplasm and the risks associated with total excision, the ultimate aims for successful care of this tumor are early clinical detection and treatment initiation [17].…”
