Summary

This case study highlights a benign schwannoma in the parotid gland. Fine-needle aspiration biopsy (FNAB) aided in the correct diagnosis, supported by a literature review of similar cases.

Area of Science:

  • Otolaryngology
  • Surgical Pathology
  • Oncology

Background:

  • Benign schwannomas are rare neoplasms originating from Schwann cells, typically affecting peripheral nerves.
  • Parotid gland tumors present a diagnostic challenge due to the variety of benign and malignant lesions possible.
  • Accurate preoperative diagnosis is crucial for appropriate surgical planning and patient management.

Observation:

  • A case of a benign schwannoma arising in the parotid gland is presented.
  • Fine-needle aspiration biopsy (FNAB) provided diagnostic clues suggesting schwannoma.
  • A comprehensive review of the literature since the 1960s was conducted to identify similar reported cases.

Findings:

  • The study emphasizes the utility of FNAB in suggesting the diagnosis of parotid gland schwannoma.
  • Differential diagnoses for parotid gland lesions on cytologic specimens are discussed.
  • This case adds to the limited literature on benign schwannoma of the parotid gland.

Implications:

  • Early and accurate diagnosis of parotid gland schwannoma can be achieved through FNAB.
  • Understanding the cytologic features of schwannoma is important for pathologists.
  • This case contributes to the knowledge base for managing rare parotid gland neoplasms.
