These ducts are mainly located in the extralobular connective tissue, composed of pseudostratified
it is a pseudostratified
epithelium comprising three cell types: adluminal cells, glandular cells, and myoepithelial cells; all of them contact the underlying basal lamina.
Ciliated surface in the oesophagogastric junction zone: a precursor of Barrett's mucosa or ciliated pseudostratified
Cystic hypersecretory hyperplasia and its malignant counterpart, cystic hypersecretory carcinoma (CHC), are the classic entities with luminal pink, proteinaceous, thyroid colloidlike material and cyst formation lined by simple to pseudostratified
to micropapillary epithelium.
1) Such an association may indicate that the ciliated, pseudostratified
, columnar respiratory epithelia that line the lungs, nose, and sinuses may share a common pathophysiology.
It is covered by a pseudostratified
columnar epithelium, lying over connective tissue and a thick layer of striated skeletal muscle with circular and longitudinal fibbers (Fig.
D, Flat low-grade dysplasia with pseudostratified
and hyperchromatic nuclei, resembling the nuclei of sporadic colonic adenoma (hematoxylin-eosin, original magnifications X40 [B], X200 [C], and XI00 [D]).
Histopathologically lining of the cyst is pseudostratified
columnar epithelium with numerous goblet cells.
The cells lining the structures can vary from columnar and pseudostratified
to focally cuboidal with eosinophilic cytoplasm.
The epididimary segment presented a pseudostratified
cylindrical epithelium, but when reaching the ampular segment the epithelium varied to a simple cuboideo one.
1,2) The tumor consists of pointed or blunt finger-like processes lined by pseudostratified
columnar epithelium (Figure 1, A).
According to the histopathologic analysis, the cyst was lined with pseudostratified
ciliated columnar epithelium, predominantly and focally squamous epithelium.
