The presence or absence of a coexisting columnar cell
lesion in the needle core biopsy was recorded.
However, noninvasive urothelial carcinoma with glandular differentiation contains atypical columnar cells
, exhibits true glandular and urothelial differentiation, and lacks stromal invasion--all features that help differentiate this entity from its morphologic mimics.
Significance of acid-mucin-positive nongoblet columnar cells
in the distal esophagus and gastroesophageal junction.
The columnar cell
variant of PTC was first reported by Evans in 1986.
In contrast, the columnar cell
type shows a high TP53 mutational frequency, with G to T transversions, considered to be caused by exogenous carcinogenic agents like those found in tobacco smoke.
The atypical cells are of flattened, cuboidal, or columnar cell
shape (Figure 3, B).
However, dirty necrosis and columnar cell
morphology with basal nuclei were also seen in rare cases of PCa (2 cases and 1 case, respectively).
The presence of florid LCIS or ADH, particularly of the columnar cell
type, are also relatively strong indications for surgery.
There are some tall columnar cells
but the nuclei are generally round and low grade.
19) Histologic examination shows anastomosing vascular channels lined with tall columnar cells
in a flat or papillary configuration.
The centrally located intestine measured 25 um in diameter, was laterally compressed, and was lined by columnar cells
with microvilli and abundant cytoplasmic granules.
The basal epithelium was composed of columnar cells
with hyperchromatic nuclei.
As the onslaught of cigarette smoke to the respiratory mucosa continues, the denuded columnar cells
differentiate and become cuboidal.
Electron microscopic evaluation of the bronchial biopsy specimens revealed ciliated cells appeared to be replaced by columnar cells
lacking cilia and basal bodies, and bearing on their surface cilium-like projections without any internal axonemal structure.
In the seep mussel Bathymodiolus heckerae, cellular contents of columnar cells
were anomalous, being dominated by an unknown cellular inclusion herein called spherical inclusion unknown or SIX.
