“…A preoperative diagnosis of schwannoma is essential as excision of schwannoma is associated with higher degrees of nerve palsy due to the close proximity to the tumor. 1 Fine needle aspiration for cytological analysis under image guidance aids in pathological confirmation of schwannoma. MRI remains as the radiological imaging of choice for delineating the extent of tumor and the relationship with adjacent vital structures and also aids in identification of the nerve of origin based on the possible enlargement or widening of the specific anatomical spaces and foramina.…”

Schwannoma also referred to as neurilemmoma or neurinomas arise from the Schwann cells of the autonomic nerves, peripheral nerves and cranial nerves except optic and olfactory nerves. Head and neck schwannomas account for 25 to 45% of schwannomas and the most common being vagal schwannomas and cervical sympathetic chain schwannomas. Schwannomas arising from the trigeminal nerve are rare and this case report consists of a schwannoma presenting as a left preauricular swelling involving the region of parotid extending from foramen ovale through the infratemporal fossa up to the parapharyngeal space. A combined preauricular trans mandibular approach enabled a complete excision of the tumor. Histopathological confirmation of a benign schwannoma was obtained and the patient is feeling well with minimal postoperative facial palsy with no trismus, occlusion abnormalities and no signs of recurrence on follow up.

SummarySchwannoma, a type of benign neurological tumour arising from Schwann cells, is commonly seen in the head and neck region. However, the incidence of cervical lymph node schwannoma is extremely rare, with only two cases reported in the literature. Schwannomatosis is a disease characterised by a constellation of multiple schwannomas seen in a patient, guided by at least one confirmational histological diagnosis. This is a case of a painless progressively enlarging submandibular swelling which is confirmed as a schwannoma based on histology. The patient is also diagnosed with schwannomatosis as the patient has multiple neurological tumours. Nodal schwannoma has a good prognosis and no documentation of recurrence in the literature. It may arise from sympathetic nerves located within the lymph node.

“…Schwannomas are rare benign tumors that arise from Schwann cells of the peripheral nerve and are mainly located in the peripheral nerves or central nervous system, although they can theoretically be found anywhere in the body where nerves reside [ 8 ]. Typically, schwannomas occur unilaterally as solitary encapsulated tumors; however, patients with neurofibromatosis are at increased risk of schwannoma and may present with these tumors in more than one site [ 5 , 9 ]. Schwannomas can cause a variety of symptoms depending on their specific location in the body and the compressive effects of surrounding structures, although they commonly tend to be asymptomatic due to their slow-growing and benign properties [ 6 ].…”

Schwannomas are rare benign tumors that are often asymptomatic and identified incidentally on imaging studies undertaken for another purpose. Schwannomas arising from the vestibular nerve are the most common site of identification; however, schwannomas can arise extracranially in any peripheral nerve tissue. Here, we present a case study of a patient with a localized rectal adenocarcinoma who was found to have a retroperitoneal schwannoma initially felt to be a lymph node metastasis of his rectal cancer. The diagnosis of schwannoma was confirmed via biopsy, which resulted in changes to the patient's overall management including radiotherapy volumes and recommendation against neoadjuvant or adjuvant systemic therapy.
