“…Eyelid primary schwannomas are exceedingly rare, constituting less than 1% of all orbital tumors. 2 However, its occurrence in the area involving the lateral canthus of eye is extremely uncommon as per our knowledge. 1,2 In this case report, we first assumed the lesion to be dermoid cyst but after surgery and histopathological analysis Schwannoma was confirmed.…”

“…These tumors may involve any nerve in the body but its most common occurrence is in the head and neck region constituting 25% to 48% of all extracranial schwannomas. 2 These may arise from all cranial nerves except the optic.

Schwannoma, also known as neurilemmoma, is a benign tumor originating from Schwann cells and may involve any nerve in the body but its most common occurrence is in the head and neck region. When it involves a nerve of face, it is often confused with dermoid cyst. We present the case of a 23-year-old male patient with Schwannoma arising from the area just below the lateral canthus of the left eye where the initial diagnostic hypothesis was dermoid cyst but later confirmed as Schwannoma on histopathological analysis.

“…Schwannomas exhibit a predilection for the head, neck, and flexor sides of the extremities, with around 45% occurring in the head and neck area. They can originate from various peripheral, cranial, or autonomic nerves and may be associated with neurofibromatosis type II [ 6 ]. Representing approximately 30% of all spinal neoplasms, schwannomas demonstrate a slight male-to-female predilection (ratio of 1.23-1.5:1), favoring males [ 7 ].…”

This case report describes an unusual presentation of schwannoma, a typically benign and solitary tumor originating from Schwann cells in peripheral nerves. While the literature on extraspinal schwannomas is limited, this report discusses the case of a 21-year-old female with complaint of a back swelling persisting for two years, causing discomfort during sleep. The oval-shaped swelling, measuring 7x6 cm, was located over the T11-T12-L1 vertebrae, with normal overlying skin, pinchable hardness, and fixation to the vertebrae. The patient had no history of pain or weakness in the lower limbs. Fine-needle aspiration cytology (FNAC) yielded inconclusive results. X-ray imaging of the thoracolumbar spine revealed a soft tissue shadow over the T11-T12-L1 vertebrae. The patient underwent complete surgical excision through a vertical incision, emphasizing the importance of preoperative imaging for accurate diagnosis, optimal surgical planning, and ensuring procedural safety.

“…Recurrence and malignant transformation are uncommon, but they can occur [ 5 ]. Schwannomas typically present in the second to fifth decade of life [ 6 , 7 ]. This is the first published report of a pediatric patient with a schwannoma originating at the lateral wall of the nasopharynx.…”

This is a case of a male child who presented with a progressively enlarging oropharyngeal mass, hyponasal voice, and symptoms of obstructive sleep apnea. Computed tomography imaging of the head and neck revealed a well-circumscribed low-density area of polypoid morphology arising from the left lateral pharyngeal wall, filling most of the posterior oropharynx and extending to a pedicle at the lateral nasopharynx. Histopathological evaluation following surgical excision revealed Antoni A tissue and S100 immunoreactivity. The presentation and diagnosis of benign schwannoma neoplasms are discussed.
