Unusual cystic epithelial choristoma in a celiac lymph node.

With the exception of müllerian-like glandular inclusions in women, reports of nonendometriotic benign glandular inclusions in abdominal lymph nodes are uncommon. We report the case of a 50-year-old woman with an apparently unique, non-müllerian, benign cystic epithelial choristoma in a celiac lymph node found incidentally at cholecystectomy. This case further expands the spectrum of benign lesions that must be differentiated from metastatic adenocarcinoma. Possible histogenesis is discussed.
