Laryngeal GCTs, particularly those affecting the vocal cords, are exceedingly rare in adults. This report presents a 28-year-old female with a GCT of the left vocal cord extending into the subglottic region. The patient presented with progressive dysphonia, and laryngoscopy revealed a 2 cm × 1 cm mass on the left vocal cord. Microlaryngeal examination confirmed subglottic extension, and the tumor was excised using carbon dioxide (CO<sub>2</sub>) laser. Histopathological analysis confirmed GCT with S100 positivity. Two months later, the patient developed a late complication - granuloma formation at the excision site - necessitating revision surgery. The patient was symptom-free at the 12-month follow-up. GCTs in the vocal cords with subglottic extension are rare and challenging to diagnose and treat. They are generally benign lesions and rarely undergo malignant transformation. Diagnosis is confirmed through histology, and treatment involves wide local excision, with re-excision needed for recurrence. GCTs are chemo- and radio-insensitive, making surgery the primary treatment.
