C, iSMILE: invasive carcinoma with nests of stratified columnar cells
and peripheral palisading.
(24) In our study, more than half of the benign lesions were fibrocystic change with or without epithelial hyperplasia, followed by columnar cell

The columnar cell
variant of PTC can pose a diagnostic challenge.
E, The peripheral lining cells of encapsulated papillary carcinoma may rarely take on the appearance of piano key-like columnar cells
with subnuclear vacuoles and reverse polarity.
The glands of tubular carcinoma are angulated and teardrop-shaped, and some show luminal cytoplasmic snouts, similar to the luminal cytoplasmic snouts seen in columnar cell
The presence or absence of a coexisting columnar cell
lesion in the needle core biopsy was recorded.
Noninvasive urothelial carcinoma with glandular differentiation is often a small lesion with papillary (fibrovascular cores lined by columnar epithelium; Figure 2, A), cribriform (columnar cells
making large or small individual glandular spaces; Figure 2, B), and flat architectural patterns (columnar cells
lining a flat surface; Figure 2, C).
papilloma is an uncommon (3-5%) variant of Schneiderian papilloma.
Significance of acid-mucin-positive nongoblet columnar cells
in the distal esophagus and gastroesophageal junction.
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 ducts and surface are similarly lined by variably vacuolated cuboidal to columnar cells
and mucus cells that are thought to secrete neutral mucopolysaccharides (Andrews 1988) (Fig.
