It is characterized as being a smaller duct made up of low
cuboidal epithelial cells, presenting a round central nucleus (Fig.
Simple tall
cuboidal to columnar epithelial "epidermal" cells, which may be pigmented, interspersed with mucus cells and ciliated cells, make up the epidermis (Fig.
Papillary cystadenocarcinomas (PCAs) are rare low-grade salivary gland tumors histologically characterized by cystic structures with frequent papillary projections, and lined by
cuboidal, columnar, or mucus-secreting cells.
The produced clay-based zeolite was found to consist dominantly of
cuboidal crystals and fits in structural framework and phase of ZSM-5 by 86.92 %.
The papillae were lined by
cuboidal cells with oval nuclei and prominent nuclear pseudo-inclusions (Figure 3a).
Microscopic findings of the postoperative specimen showed a mixture of papillary and sclerotic patterns with two cell types as follows:
cuboidal surface and stromal round cells.
Pathological examination revealed gastric adenomyoma, which was composed of cysts and glandular structures lined by
cuboidal to columnar epithelium surrounded by hypertrophic smooth muscle bundles.
The islands show the features of duct-like structures with an inner layer of
cuboidal or columnar cells [Figure 6].
Cuboidal or columnar cells are seen lining duct-like spaces and clefts.4
However, four distinct crystal morphologies are apparent: the typical bipyramidal crystal, related to Cry 1 proteins,
cuboidal inclusions related to Cry 2 proteins and usually associated with bipyramidal crystals, amorphous and composite crystals releated to Cry 4 and Cyt proteins and flat, square crystals, related to Cry 3 protein (Lopez-Meza and Ibarra, 1996).
In the histological examination, the cyst was lined by flattened,
cuboidal or ciliated columnar epithelium supported by underlying fibrous stroma (Figure 2b).
