Adenoid Cystic Carcinoma, Esophageal
Adenoid cystic carcinoma is a basaloid tumor consisting of epithelial and myoepithelial cells (WHO) in variable architectural configurations, including tubular, cribriform, and solid patterns.
Adenoid cystic carcinoma is extremely rare in the esophagus, accounting for less than 0.1% of esophageal carcinomas.
Most patients are in their seventh decade.
Males are more commonly affected with a reported M-F ratio of 3:1.
More than half of the cases occur in the middle third of the esophagus. They rarely arise in the upper third.
Surgery is the treatment of choice. In cases with positive margins, radiotherapy is warranted.
The prognosis is poor, usually fatal. However, some cases have slow progression over large periods of time. Recurrence is found in regional lymph nodes as well as distant organs.
The most common macroscopic presentation pattern is as an intraluminal, polypoid mass. Four...
