The cells lining tubules, cysts, and papillae are cuboidal
to low columnar with scant pale cytoplasm (Figure 1, A and B).
Under the microscope, eccrine hidrocystomas appear as unilocular cysts, which usually contain a single cystic cavity composed of 1 or 2 layers of cuboidal
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.
Cysts lined with stratified squamous epithelium and simple cuboidal
epithelium have also been observed.
This tumor was composed of tubulocystic and papillary glands lined by glycogen-rich, cuboidal
, or hobnail cells with clear to eosinophilic cytoplasm.
Most of the epithelia in the two areas were pseudostratified cylindrical ciliated epithelium with goblet cells (respiratory epithelium), stratified cuboidal
epithelium, and stratified squamous nonkeratinized epithelium.
23) Consistent with the immunohistochemistry results, the cuboidal
cells were shown to express cytokeratin, epithelial membrane antigen, surfactant, and TTF-1.
cells lining the pseudopapillae were strongly positive for glial fibrillary acidic protein [GFAP, [Figure 1]e and vimentin but were negative for neuron-specific enolase (NSE) and neuronal nuclear antigen [NeuN, [Figure 1]f, suggesting glial differentiation.
Right: There are cuboidal
to columnar cells lining the papillary structures; the fibrovascular cores are heavily collagenized.
The intercalated duct cells appeared cuboidal
to low columnar with the broader base.
A, Neoplastic cells are cuboidal
and, although atypical, relatively uniform from cell to cell.
the epithelial lining of follicular variant are cuboidal
and columnar ,the nuclei are present on the opposite pole of the basal membrane.
