Abstract:
A rare case of spontaneous regression of a pedunculated vallecular hemangioma in a 55-year-old male is presented. Following an incisional biopsy, the lesion regressed completely within three weeks, confirmed by imaging and direct laryngoscopy. This case highlights an unusual clinical outcome and raises questions about the mechanisms underlying hemangioma regression in adults.
