Neurofibroma is a benign tumor of the connective tissue developed mainly at the expense of the endoneurium of the peripheral nerves. Histologically, there are two types of neurofibroma: plexiform and solitary. The objective of this work was to report a case of solitary nasosinusal neurofibroma in order to discuss diagnostic and therapeutic difficulties in a developing country. BA aged 17, with no known pathological history, was admitted to the service for a left nasal obstruction which had been evolving for about 4 years. The endonasal examination found a congestive mass, not bleeding on contact, filling the entire left nasal fossa pushing back the nasal septum on the right. Computed tomography showed a heterogeneous dense tissue process with cystic areas, filling the left nasal fossa with extension to the posterior sinuses, left maxilla. The patient was operated under general anesthesia via the left paralateronasal route. The tumor was difficult to cleave but not friable and not bleeding. The histological examination concludes to a neurofibroma. Conclusion: Solitary neurofibromas are uncommon and remain poorly understood. Literature data, rare, do not answer all the questions.

“…Signs and symptoms depend on the anatomical site involved, the nerve of origin and the extent of the tumor. The signs are usually those of a tumor developing in the nasosinus cavities [10,11]. One can find, among other things, mucopurulent rhinorrhea, nasal obstruction, epistaxis, anosmia, facial deformity, proptosis and facial pain.…”

“…Very rarely, in tumor area there is necrosis and cystic degeneration. 5 Plexiform neurofibroma is an unusual histological variant of NF and is described as a benign tumor of nerve sheath origin involving multiple nerve fascicles of the smaller branches of peripheral nerves. Plexiform neurofibroma can be sporadic without systemic or familial involvement.…”

“…• Pacinian-A type of NF where small round whorled structures resembling Pacinian body-like structures are present as prominent feature. 5 The histopathological differential diagnosis of neurilemmoma, leiomyoma, and fibrous histiocytoma was considered. Neurilemmoma unlike NF will show encapsulated mass as well as hypercellular and hypocellular areas.…”

Neurofibroma is a slow growing benign tumour of the peripheral nerve sheath which is frequently associated with neurofibromatosis type 1 (Prakash et al., 2014). Isolated solitary occurrence of neurofibroma in the maxillary sinus is rare with only 29 reported cases in the literature. We present a rare case of a 70-year-old gentleman who was referred to ENT with a right maxillary sinus neurofibroma with extension into the right inferior orbit. He has significant proptosis, ptosis, and limitation in abduction of the right eye. He has a complicated past history of multiple neurofibromas which were completely excised. Craniofacial MRI shows a large mass filling the right maxillary antrum extending anteriorly into subcutaneous tissue towards nasal ala and posterolaterally into inferior temporal fossa and superiorly into orbit and cavernous sinus involvement. Biopsy of the right maxillary mass revealed cellular spindle cell tumour with wavy collagen bundles within myxoid stroma which is consistent with a neurofibroma. Patient's case was discussed in the skull-base MDT and he has been referred to a specialist center for surgical removal of the neurofibroma with reconstructive surgery. Despite the rarity of this disease, otorhinolaryngologist should consider a possibility of neurofibroma of the paranasal sinuses.
