Microscopically, the lesions are composed of intraductal nodules of tightly packed, small tubular glands and solid areas lined by predominantly cuboidal cells
with modest amounts of cytoplasm, which do not contain any apparent mucin.
13) The epithelial component is typically composed of small tubules lined by columnar or cuboidal cells
, and the tumor may demonstrate rosetting, tubular, and papillary patterns.
These are: (1) the cuboidal cells
with round nuclei with euchromatin and distinct nucleoli on the lateral side; (2) the tall columnar cells with round or oval nuclei located in the terminal epithelium; (3) the ciliated columnar ceils in the distal end of the filament; (4) the mucus cell with numerous dense granules packed tightly together in the apical cytoplasm (Fig.
The histological study showed encysted tubular structures lined with flattened cuboidal cells
, consistent with vesical nephrogenic adenoma (Fig.
17) However, IPC is characterized by the presence of papillary fronds lined by cuboidal cells
that often reveal higher-nuclear-grade cytology.
Multifocal islands and tapered cords of cuboidal cells
were present within the submucosa.
The lesion is composed of many glands lined by columnar or cuboidal cells
and surrounded focally by urothelial cells.
The epithelium may demonstrate clearly benign cuboidal cells
or different phases of potential malignant progression, including atypia, dysplasia, carcinoma in situ, micropapillary projections, and/or invasive carcinoma.
The large cells are epithelioid, cuboidal cells
that line the exterior of the alveolar spaces or trabeculae.
Cells adjacent to the fibrous layer of the periostracum are cuboidal cells
of approximately 15 [micro]m in height with circular nuclei in the middle cytoplasm.
