Epithelial polarity is one example of the cell polarity that is a fundamental feature of many types of cells. Epithelial cells feature distinct 'apical', 'lateral' and 'basal' plasma membrane domains. Epithelial cells connect to one another via their lateral membranes to form epithelial sheets that line cavities and surfaces throughout the ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
This is a shortened version of the second chapter of the ICD-9: Neoplasms. It covers ICD codes 140 to 239. The full chapter can be found on pages 101 to 144 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Carcinoma is but one form of cancer—one composed of cells that have developed the cytological appearance, histological architecture, or molecular characteristics of epithelial cells. [ 5 ] [ 6 ] A progenitor carcinoma stem cell can be formed from any of a number of oncogenic combinations of mutations in a totipotent cell, [ 12 ] a multipotent ...
They are classified according to the specific type of epithelial cells that are affected. [ 1 ] The most common epitheliomas are basal cell carcinoma and squamous cell carcinoma (skin cancers).
Epithelial cells also exhibit planar cell polarity, in which specialized structures are orientated within the plane of the epithelial sheet. Some examples of planar cell polarity include the scales of fish being oriented in the same direction and similarly the feathers of birds, the fur of mammals, and the cuticular projections (sensory hairs ...
Approximately 98% of lung cancers are carcinoma, a term for malignant neoplasms derived from cells of epithelial lineage, and/or that exhibit cytological or tissue architectural features characteristically found in epithelial cells. [8] Under WHO-2004, lung carcinomas are divided into 8 major taxa: [1] Squamous cell carcinoma; Small cell carcinoma
The epithelial cells tend to move the nucleus away from the basement membrane to the opposite pole of the cell. This process is called reverse polarization. Two main histological patterns most often occur: follicular and plexiform. Other less common histological variants include acanthomatous, basal cell, and granular cell patterns. [8]
