Transitional epithelial cells, also known as urothelial cells, line the urinary tract from the renal pelvis through the ureters and bladder and, in males, the upper portion of the urethra. They are smaller than squamous cells and their shape varies based on the layer of epithelium from which they are derived, but they are most commonly round or ...
Epithelioid cells gather around the focus of necrosis, in direct contact with the necrotic masses, forming a kind of boundary zone.. Structurally, epithelioid cells (when examined by light microscopy after stained with hematoxylin and eosin), are elongated, with finely granular, pale eosinophilic (pink) cytoplasm, and central, ovoid nuclei (oval or elongate), which are less dense than that of ...
Simple columnar, non-ciliated: intestinal epithelium: digestive: rectum: Simple columnar, non-ciliated - digestive: anus: Stratified squamous, non-keratinized superior to Hilton's white line Stratified squamous, keratinized inferior to Hilton's white line - digestive: gallbladder: Simple columnar, non-ciliated - endocrine: thyroid follicles ...
Perivascular epithelioid cell tumour, also known as PEComa or PEC tumour, is a family of mesenchymal tumours consisting of perivascular epithelioid cells (PECs). [1] These are rare tumours that can occur in any part of the human body. The cell type from which these tumours originate remains unknown.
Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei.. Simple cuboidal epithelium is found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, parts of the eye and thyroid, and in salivary glands.
Clear cell RCC, an epithelial cell tumour of the kidney that accounts for 65-70% of all RCCs. [5] Papillary RCC, a renal tumour that accounts for 10-15% of all RCCs. Males are 1.5 times as likely to develop this type of tumour than females. Papillary RCCs, usually lead to a better prognosis than clear cell RCCs unless the tumour has metastasized.
Decoy cells are virally infected epithelial cells that can be found in the urine. Decoy cells owe their name to their strong resemblance to cancer cells, and may as such confuse the diagnosis of either viral infection or urothelial malignancy. During 1950s, cytotechnologist Andrew Ricci observed cells mimicking cancer cells by they were not, in ...
The urine test strip test for white blood cells detects leukocyte esterase, which is present in azurophilic granules of monocytes and granulocytes (neutrophilic, eosinophilic and basophilic). Bacteria, lymphocytes and epithelial cells from the genitourinary tract do not contain esterases. [21]
