Approximately 7 cases of spontaneous regression of adult laryngeal carcinoma have been published in the literature since 1900. This case presents a 62-year-old male with a 6-month history of hoarseness who was subsequently diagnosed with a T1aN0M0 left true vocal fold squamous cell carcinoma (SCC) after biopsy. One month following the initial biopsy, histopathological findings on repeat biopsy revealed absence of malignancy and regression of the tumor without radiation. There has been no evidence of tumor recurrence. This case exemplifies how innate immune modulation may play a role in the spontaneous regression of laryngeal SCC, although the mechanism remains unknown.
