An 8-year-old child was admitted to our ENT department for a year because of a hoarse voice. An endoscopic examination displayed that a cystic, solid lesion can be seen in the right subglottis. The lesion was removed using a CO2 laser under general anesthesia. Postoperative histopathology confirmed granular cell tumor (GCT), S-100(+), vimentin (+), and SOX-10(+). GCT, also known as the Abrikossoff tumor, is a rare benign tumor that rarely occurs in the larynx, particularly in children. This case report emphasizes that considerable attention should be given to the differential diagnosis of the laryngeal granulosa cell tumor. Given the recurrence risk of GCT, long-term postoperative follow-up is necessary.
