(63-65) In some cases, a minor adenocarcinomatous component may be present but may not meet the 10% requirement for the adenosquamous classification.
The mucin secreted by adenocarcinomatous cells is mainly intestinal acidic mucins, which was strongly positive for Alcian Blue at PH 2.5 (Fig.
In this study, the patient with the adenocarcinomatous pedunculated polyp was positive for MUC5AC with Western blotting (not shown).
[8,29,33,34] When they appear adenocarcinomatous, well-formed mucin-secreting glandular structures can sometimes be seen.
[26] In our study, one case of Krukenberg's and one case of metastatic adenocarcinomatous deposit was reported.
(36) In other references, the term mixed carcinoid/adenocarcinoma is not specifically used; however, the poor prognostic significance of a large (>50%) adenocarcinomatous component in GCTs is recognized.
(5,166) The adenocarcinomatous component is always closely associated with the squamous elements, and it lacks the characteristic features of a distinctive form of salivary gland-type adenocarcinoma.

In contrast, a tumor with both typical urothelial carcinoma and adenocarcinomatous components is classified as urothelial carcinoma with glandular differentiation.
