title: The cytopathologic diagnosis of esophageal adenocarcinoma.
abstract: The diagnostic cytologic features were analyzed in 18 cases of histopathologically proven esophageal adenocarcinoma accessioned at the Johns Hopkins Hospital between 1975 and 1988 for which cytologic material was available. Primary esophageal adenocarcinoma was diagnosed in 15 of 18 cytologic specimens (83%); in 3 cases (17%), carcinoma was suspected, but the changes were nondiagnostic. The most consistent cytologic changes included both architectural features (loss of orientation and nuclear crowding) and criteria of malignancy (high nuclear/cytoplasmic ratios and prominent nucleoli). In the 15 diagnostic cases, the nucleoli were small in 8 and round in 11; in the majority of these cases, the nuclei contained one to three nucleoli. In addition, nuclear and cytoplasmic molding was seen in 9 of these 15 cases, hyperchromasia was present in 8, coarse chromatin clumps were seen in 5, and tissue fragments tended to be multilayered. Review of the three nondiagnostic cases showed that scant material was present in two; the third case had abundant material, but only nondiagnostic changes, suggesting a sampling error. Barrett mucosa was seen in 7 of the 18 cases. These cases show that esophageal adenocarcinoma can be reliably diagnosed on cytologic preparations, based on the consistent architectural features and the usual cellular criteria of malignancy.
