Histological examination of the specimen showed encysted tubular structure which was lined with flattened cuboidal cells
and the features were reported to be consistent with nephrogenic adenoma of the urinary bladder.
In both enlarged and narrow regions of the gastric caeca-like structure, the wall presents a simple epithelium of cuboidal cells
each with a well-developed central nucleus with an evident nucleolus (Figs.
The epithelial structures were composed of pleomorphic columnar and cuboidal cells
, with nuclear atypia and high mitotic activity what help us to diagnose malignancy.
The CA is the only identified tumour with pure luminal cell differentiation.8 Histologically CAs are composed of isomorphic columns of columnar and cuboidal cells
with small cystic spaces with or without connective tissue capsule.4-7The BCA consisted of cords, neoplastic cells which were demarcated from surrounding stroma by a peripheral row of cells showing prominent nuclear palisading.5 Immunohistochemical analysis is an important point to differentiate the CA from other salivary gland neoplasms such as polymorphous low-grade adenocarcinoma (PLGA) and BCA.3,6 Immunohistochemical profiles of CA and BCA\'s are also different.
The acini were lined by a single layer of plump, cuboidal cells
with a centrally positioned, round to oval nucleus, surrounded by uniformly granular cytoplasm.
On further histological examination, the tumor was observed to be hypercellular, with well-defined nests of cuboidal cells
("zellballen pattern") separated by highly vascularized fibrous septae (Figure 2A).
* Cuboidal cells
of the germinal epithelium develop vacuoles and become necrotic.
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.
The tumour consists of sheets of uniform small cuboidal cells
connected by intercellular bridges, with intervening secretion filled narrow ductal lumina lined by eosinophilic cuticle (Fig2).
(8,9) PLGA cytology is characterized by the presence of cuboidal cells
with abundant cytoplasm, round to oval nuclei, and inconspicuous nucleoli.
Primordial spine formation began a short distance into the dermis where this band bifurcated to form a sheet of more or less cuboidal cells
. The advancement of this sheet's leading edges was at first primarily ventro-lateral, but then growth turned inward so as to enclose a region of the mesenchyme.
LpI was first found in stage 5 embryos and appeared to be synthesized by lateral basophilic cuboidal cells
that demonstrated cytoplasmic immunoreactivity for LpI at their interface with the yolk mass.
