Area of Science:

  • Oncology
  • Pathology
  • Head and Neck Surgery

Background:

  • Granular cell tumor (GCT) is a rare neoplasm of probable neuroectodermal origin, first described by Abrikossoff in 1926.
  • GCTs predominantly affect the head and neck region, accounting for approximately 50% of all reported cases.
  • Laryngeal localization represents a small subset, occurring in about 10% of head and neck GCTs.

Observation:

  • This report presents an infrequent case of glottic granular cell tumor.
  • The tumor was successfully managed through surgical excision with clear margins.
  • The case highlights the clinical and pathological features of laryngeal granular cell tumors.

Findings:

  • The study reviews the specific characteristics of laryngeal granular cell tumors.

Related Experiment Videos

  • Immunohistochemical techniques were employed to elucidate the pathological features.
  • The successful surgical outcome underscores the efficacy of complete excision.

    • Implications:

    • This case contributes to the understanding of rare glottic neoplasms.
    • It emphasizes the importance of considering GCT in the differential diagnosis of laryngeal masses.
    • The findings support surgical intervention as a primary treatment modality for localized glottic GCTs.
