Abstract

Schwannoma is a slow-growing, benign, encapsulated tumour of Schwann cells, which form myelin in peripheral nerve. It is the most common tumour of peripheral nerve, also known as neurilemma or neurinoma. Schwannomas of head and neck area are common and may arise from peripheral, central or autonomic nerve but salivary gland schwannomas are rare extracranial forms. The present study reports a rare case of schwannoma of the submandibular gland in a 42-year-old male patient which is presented with a painless mass in the submandibular region, treated by total excision of the submandibular gland. There were postoperative nerve deficit and no recurrence within 3months of follow up.

Highlights

Schwannomas are benign, solitary and welldifferentiated tumours originating from Schwann cells [1]
45% of all schwannomas occur in the head and neck area, where they may originate from any of the peripheral, cranial or autonomic nerves [2]

Summary

Introduction

Schwannomas are benign, solitary and welldifferentiated tumours originating from Schwann cells [1]. 45% of all schwannomas occur in the head and neck area, where they may originate from any of the peripheral, cranial or autonomic nerves [2]. These benign tumours occur regardless of age or sex and are painless, insidious and slow-growing [3]. After careful dissection and identification of adjacent anatomical structures total excision of submandibular gland along with swelling done. A 42 years old male presented to the department of otorhinolaryngology of Mahavir institute of medical sciences Vikarabad with painless swelling in right submandibular gland region forthe last 5 months and loss of sensation of taste since 2months on the. Cytoplasm suggestive of chronic submandibular sialadenitis and advised excision biopsy for confirmation
