Pediatric Laryngeal Granular Cell Tumor: Case Report and Literature Review

Granular cell tumors (GCTs) are rare benign tumors that can occur in any part of the body. They are most commonly found in the head and neck region, especially the tongue. Laryngeal GCTs are rare, accounting for only 3% to 10% of all GCTs. This case report describes a 4-year-old boy with a laryngeal GCT. The patient presented with a history of hoarseness for 2 years. Stroboscopy revealed a large mass occupying the entire length of the left vocal cord. The mass was successfully removed by microlaryngeal surgery with laser ablation. The patient's symptoms resolved after surgery, and he had an uneventful recovery. This case highlights the importance of considering GCTs in the differential diagnosis of patients with hoarseness. Early diagnosis and treatment can lead to excellent outcomes.
