7) Rarely, TIC may have an endometrioid appearance ("endometrioid TIC") characterized by stratified columnar epithelium
with a lower nuclear to cytoplasmic ratio.
In our case, the histopathologic findings demonstrated an inner surface of the cyst covered by a mucinpositive columnar epithelium
connected to urothelium, with continuous transition between the two, suggesting that the mucinous tumour may have originated from a sequestered segment of the renal pelvic epithelium in the renal parenchyma.
The mucosal surface consists of simple columnar epithelium
Microscopically, both the surface and the clefts were covered with a ciliated pseudostratified columnar epithelium
Barrett's oesophagus (BO) is defined as the occurrence of metaplastic, specialised columnar epithelium
lining the distal part of the oesophagus.
Microscopic examination of the lesion showed cystic spaces and ducts lined predominantly by flattened and, to a lesser extent, by columnar epithelium
, identical to that seen within the normal epididymis.
Barrett esophagus is defined as the development of a specialized columnar epithelium
that replaces the normal squamous epithelium of the esophagus.
Bronchoscopy will often reveal a transformation of tissue from normal columnar epithelium
into squamous epithelium, even when the reflux is nonacidic, but beyond that, finding the proper context for tissue changes such as cobblestoning and ruling out non-LPR origins can be a challenge.
35) The difference in the histologic appearance of the lining epithelium in these 2 cases might be related to a different branchial origin, with ectoderm (cleft) giving a squamous epithelium in case 1 and endoderm (pouch) generating a columnar epithelium
in case 2.
Histologic analysis showed smooth muscle hyperplasia with several dilated cystic spaces lined by columnar epithelium
containing inspissated bile (Figure 4).
Normally, most of the lower respiratory tract is lined with pseudo-stratified, ciliated, columnar epithelium
Female adolescents are biologically at higher risk for STDs such as chlamydia and gonorrhea because of the columnar epithelium
on their ectocervix, said Dr.
