Abstract
This paper focuses on the case of intrabony mandibular schwannoma in a 39 yrs healthy male who was addressed by his dentist for an asymptomatic radiolucency of the left mandibular corpus. Computed Tomography Dentascan showed a soft tumour continuous to the path of the inferior alveolar nerve. Confirmation was made after surgical excision and careful histological examination. Radiolucent images of the mandible are frequently met by dentists and oro-facial surgeons, and suggest first odontogenic cysts because of their high frequency. But even if sheath nerve tumours are very rare, this case report reminds the necessity to keep them in mind.
Highlights
Schwannoma, known as neurilemmoma or neurinoma, is a slow growing benign tumour taking its origin from the sheath of peripheral myelinited nerves, mostly sensitive nerves
Three mechanisms by which schwannomas involve bone were described: a) They may arise centrally within bone, b) they may arise within the nutrient canal and produce canal enlargement as we see in this case, or c) a soft tissue ou periosteal tumour may cause erosion or penetration into bone [3]
Imaging methods allowed us to evoke a lesion linked to the inferior alveolar nerve, even if an ameloblastoma or another odontogenic lesion remained a probable differential diagnosis, especially because of the presence of a concurrent radiolucent image linked to a small inflammatory dental cyst of the root of tooth 34
Summary
Schwannoma, known as neurilemmoma or neurinoma, is a slow growing benign tumour taking its origin from the sheath of peripheral myelinited nerves, mostly sensitive nerves. The head and neck location seems to be affected in 24% - 48% with a predilection for soft tissues. Intraosseous schwannomas represent a rare condition since schwannomas represent less than 1% of primary benign bone tumours [1] [2]. Literature reports nearly 60 cases of true intrabony schwannomas of the jaw. We present another case of intraosseous schwannoma of the mandible and review of literature.
