“…Bhola et al described a tongue tumour in a paediatric patient [24]. This finding in the paediatric population should also be differentiated from the ectopic thyroid gland or the Abrikosov tongue lesion [20,21,25]. Additionally, the floor of the mouth or gingiva, which are closely related to the teeth, can be places where SC occurs.…”

“…On the other hand, CD57+ cells are more common in traumatic neuromas. Another feature to be noted is the pattern of eosinophilic areas, whether an Antoni A-type (Verocay bodies) or a B-type (cha-otic pattern), as this helps to identify the type of SC [26][27][28]. The so-called Verocay bodies are named after palisaded nuclei that appear in the microscopic evaluation.…”

“…The so-called Verocay bodies are named after palisaded nuclei that appear in the microscopic evaluation. This approach might also be helpful in identifying the type of ONT, whether SC or neurofibroma [26][27][28]. Finally, histopathological variants of SC include ancient schwannoma, pseudo glandular schwannoma, plexiform schwannoma, cellular schwannoma, epithelioid schwannoma, and melanotic schwannoma [22][23][24][25][26][27][28][29].…”

Cone-beam computed tomography (CBCT) remains the diagnostic modality of choice. The involvement of the cortical bone and adjacent teeth can be easily established via CBCT. Magnetic resonance can be helpful in the estimation of any other soft-tissue tumour spread within this anatomical area. The soft, hard-tissue, or mixed aetiology of tumours requires a differential diagnosis and accurate evaluation. If such pathologies arise, an adequate biopsy or incisional biopsy is essential to evaluate the type of tumour histopathologically. The occurrence of some neural tumours in the oral cavity is rare. Schwannomas (SCs), like some neuromas and other types of neural tumours, are rare and atypical. During clinical examination, a smooth, sponge-like, elastic mass could indicate other small salivary gland tumours rather than an oral neural tumour. Such pathologies of neural origins are quite rare and are uncommon findings in the oral cavity; therefore, their appearance may be conflated with other more typical benign or malignant tumours in the oral cavity. Establishing the status of bone via CBCT, the tooth involvement and the composition of the cortical bone may be helpful for establishing the best treatment of choice. The presented case report describes a rare schwannoma localised at the mandibular retromolar trigone.

“…Moreover, these tumors have been rarely reported in unusual locations such as gingiva. 5,6 Schwannoma is considered as a benign peripheral nerve sheath tumor that stems from the slow proliferation of Schwann cells. Schwannoma mostly appears as a solitary nodule with slow growth which can be histologically classified into cellular, plexiform, and melanotic variants.…”

Introduction: Intraoral benign and malignant nerve sheath tumors (BNST and MNST) are rare tumors with non-specific clinical presentations and represent diagnostic and therapeutic challenges. Current knowledge regarding their demographic, clinicopathological features and treatments remains fragmented. Materials and Methods: The original data about patients diagnosed as intraoral BNST and MNST were retrieved from our disease registry (2005–2017). Comprehensive reviews of English and Chinese literature were performed to collect and analyze the epidemiological, clinicopathological data and treatment outcomes about those published cases. Results: Thirty-four intraoral BNSTs were found at our institution in the past 13 years. Literature reviews identified 354 intraoral BNSTs in 223 articles and 60 intraoral MNSTs in 50 articles. Most intraoral BNSTs and MNSTs were presented in the second to fifth decade of life. Males outnumbered females in MNSTs, while BNSTs displayed a slight female preponderance. The common sites for intraoral BNSTs were parapharyngeal space followed by tongue, whereas mandible was the most common site for MNSTs. Most intraoral BNSTs were presented as slow-growing, painless mass or swelling, while MNSTs usually appeared as painful and invasive mass with discomfort. Surgical excision was preferred for intraoral BNSTs with excellent prognosis. Complete resection was indicated for intraoral MNST with dismal prognosis as evidenced by much recurrence, metastasis, and death. Conclusion: Intraoral BNST and MNST are rare diseases which should not be ignored when intraoral painless or painful mass/swelling is found. Surgical excision is indicated for intraoral BNST with favorable outcomes. However, further investigations are warranted to optimize the treatment for intraoral MNST to improve its prognosis.
