(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.
 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.
