Adenosquamous carcinoma in the duodenum is extremely rare disease entity and only 6 cases were reported all over the world so far. Recently we encountered a 62 year-old female patient with duodenal adenosquamous carcinoma. The patient subsequently underwent Whipple’s operation. Histopathologic examination revealed two pathologic components composed of adenocarcinoma and squamous cell carcinoma. The metastatic foci of lymph nodes were composed of pure squamous cell carcinoma. For differential diagnosis, we performed several special stains including high molecular weight cytokeratin(HMWCK), low molecular weight cytokeratin(LMWCK), carcinoembryogenic antigen( CEA), mucicarmine, periodic acid-Schiff(PAS). Immunohistochemical stains demonstrated LMWCK, CEA, mucicarmine positivity for glandular component and HMWCK for squamous component. Weak positivity for squamous component was observed with PAS stain. The pathogenesis of adenosquamous carcinoma is controversial issue and not resolved yet, so we discussed the histogenesis of adenosquamous carcinoma.
