Adenocystic carcinoma accounts for 3-5% of all malignant neoplasms of the head and neck organs. Due to the rarity of detecting this cancer in the larynx, treatment options are still controversial: surgery with postoperative radiation therapy or surgery alone. Patient A., 64 years old, turned to the City Clinical Oncological Hospital No. 1 in October 2019 with complaints of moderate pain when swallowing, sensation of a foreign body. Fibrolaryngoscopy revealed an exophytic form of growth bright red color formation with a small tuberous surface up to 12 mm in size in the area of the free left edge of the epiglottis. There was a thickening of the pharyngeal-epiglottis fold. Histological examination revealed adenocystic cancer. Diagnosed with Laryngeal cancer with cT1N0M0. On December 23, 2019, endolaryngeal resection of the larynx was performed using an operating microscope in the volume R0. This observation is of interest both in morphological terms (extremely rarely detected cancer of the larynx) and in terms of treatment (an organ-preserving operation was performed — endolaryngeal resection of the larynx).
