A case of primary adenoid cystic carcinoma of the esophagus is reported and a total of 15 cases was reviewed. There were 9 men, although earlier reports indicated the disease was more common in women. The lesion was located in the middle third of the esophagus in 10 cases. The possibility of tumor development from embryonal rests of the tracheobronchial tree in the esophagus is discussed. The prognosis of adenoid cystic carcinomas is not well known, but the treatment and prognosis appear similar to those of epidermoid carcinomas of the esophagus.

(1) : Salivary gland tumors (SGTs) are a rare and diverse group of neoplasms arising in the parotid, submandibular, sublingual, and minor salivary glands distributed throughout the upper aerodigestive tract. Given the rarity and complexity of MSGTs, understanding their epidemiology across diverse populations is crucial for improving diagnostic and therapeutic strategies. (2) : A retrospective analysis involving 45 patients diagnosed with malignant salivary gland tumors and treated with curative intention between 1 July 2016 and 1 July 2021 in a tertiary academic hospital was performed.

Given its protracted growth, ACC is usually diagnosed in advanced stage. Treatment of ACC is limited to surgery and/or adjuvant radiotherapy, which often fails to prevent disease recurrence, and no FDA-approved targeted therapies are currently available.
