Various Causes of Carcinoma

Vlad Herlea

Carcinoma is a malignancy that develops from epithelial
cells. Specifically, a carcinoma is a cancer that begins in a tissue
that lines the inner or outer surfaces of the body, and that arises
from cells originating in the endodermal, mesodermal
or ectodermal germ layer during embryogenesis.carcinoma has
also come to encompass malignant tumors composed of
transformed cells whose origin or developmental lineage is
unknown (see cancer of unknown primary origin; CUP), but
that possess certain specific molecular, cellular,
and histological characteristics typical of epithelial cells. This
may include the production of one or more forms
of cytokeratin or other intermediate filaments, intercellular
bridge structures, keratin pearls, and/or tissue architectural
motifs such as stratification or pseudo-st claratification.
