[Cystic adenoid carcinoma of the esophagus. Description of a case and review of the literature].

The clinical and histopathologic characteristics of a case of adenoid cystic carcinoma of the esophagus are reported. The authors reviewed the literature on the matter and stressed the more aggressive behaviour of the tumor that differs from the same tumor of the salivary glands and other anatomical sites. Surgical resection is the treatment of choice, however the aggressiveness of the tumor requires, also, a chemo and radiotherapeutic approach.
