carcinoma (kär´sinō´m
),n a malignant epithelial tumor. Also called
cancer.
cancer.
carcinoma, adenoid cystic,
n a salivary gland malignancy of ductal and myoepithelial cells that may arise in both major and minor salivary glands. Although it grows slowly, perineural invasion and its relentless nature makes long-term survival poor.
carcinoma, basal cell
n an epithelial neoplasm with a basic structure resembling the basal cells of the epidermis. It develops from basal cells of the epidermis or from the outer cells of hair follicles or sebaceous glands, particularly the middle third of the face. It rarely, if ever, metastasizes but is locally invasive. It does not arise from oral mucosa. It develops as a plaque that then ulcerates in the center, becoming indurated.
carcinoma, basosquamous,
n a carcinoma that histologically exhibits both basal and squamous elements. It may occasionally be seen in the oral cavity; considered to have a greater tendency to metastasize than does basal cell carcinoma.
carcinoma, epidermoid
n a malignant epithelial neoplasm with cells resembling those of the epidermis. The term
squamous cell carcinoma is used for intraoral lesions of this nature. See also carcinoma, squamous cell (SCC).
squamous cell carcinoma is used for intraoral lesions of this nature. See also carcinoma, squamous cell (SCC).
carcinoma, exophytic,
n a malignant epithelial neoplasm with marked outward growth similar to a wart or papilloma.
carcinoma in situ,
n a dysplastic epithelial disease involving the skin and mucous membranes and considered to be precancerous. Dysplasia (premature keratinization) is evident, but no invasion has yet occurred.
carcinoma, intraepithelial,
n See carcinoma in situ.
n a malignant epithelial tumor of the salivary gland characterized by acini with mucus-producing cells.
carcinoma, squamous cell (SCC),
n the second most common skin cancer after basal cell carcinoma. It arises from the epidermis or oral mucosa and resembles the squamous cells that comprise most of the upper layers. It may occur on all areas of the body, including the mucous membranes, but is most common in areas exposed to the sun. Risk factors include actinic (sun) damage, alcohol use, and tobacco use.

Squamous cell carcinoma.
carcinoma, transitional cell,
n a malignant tumor arising from a transitional type of stratified epithelium.
carcinoma, verrucous,
n a squamous cell carcinoma, usually intraoral, that is exophytic and has a papillary appearance. Associated with spit tobacco.
verrucous carcinoma
A WD SCC of the oral cavity, larynx, nasal cavity, esophagus, penis, anorectal region, vulva, vagina, uterine cervix and skin, especially on the sole of the foot; intraoral VCs occur in elderly ♂ smokeless tobacco
