These ducts are mainly located in the extralobular connective tissue, composed of
pseudostratified columnar epithelium.
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 metaplasia.
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.
