| squamous cell carcinoma n. A carcinoma that arises from squamous epithelium and is the most common form of skin cancer. Also called cancroid, epidermoid carcinoma. |
squamous cell carcinoma,
a slow-growing malignant tumor of squamous epithelium, frequently found in the lungs and skin and occurring also in the anus, cervix, larynx, nose, and bladder. The neoplastic cells characteristically resemble prickle cells and form keratin pearls. Also called epidermoid carcinoma.
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.

n a squamous cell carcinoma, usually intraoral, that is exophytic and has a papillary appearance. Associated with spit tobacco.
squamous
scaly or platelike.
squamous bone
the pars squamosa, or squamous portion of the temporal bone.
squamous cell carcinoma

In animals they occur on the conjunctiva, the mouth, salivary duct, stomach, trachea and bronchi, prostate, penis, prepuce, vulva, urinary bladder and skin. See also specific organ locations.

squamous metaplasia
affected cells are converted to a squamous stratified type from the surface of which squames are shed.
ocular squamous cell carcinoma
that arising from squamous epithelium and having cuboid cells. Squamous cell carcinoma around the eye, also known as cancer eye, is a common neoplasm in cattle, especially those breeds with little pigment in the eyelids. Sunlight, viruses, skin pigmentation and heredity are all thought to be involved in causing the disease. Lesions begin on the third eyelid, unpigmented eyelid or vascular cornea. They are fungating masses of tissue, usually ulcerated, necrotic and apparently painful. They grow rapidly and commonly invade the local lymph nodes. Similar lesions occur on the eyeball and eyelid of the horse. What makes the cattle disease so remarkable is the high prevalence rate. Called also cancer eye.
Squamous cell carcinomas are among the most common skin tumors in dogs and cats. They are particularly common in sun-exposed areas of skin such as the pinnae, eyelids or noses of white cats. Tumors are locally invasive and slow to metastasize.
squamous papilloma
the common papilloma in all species except cattle and deer. Composed largely of epithelial tissue in contrast to fibropapillomas but many lesions are intermediate in type.
squamous pearl
see horn pearls.
squamous cell carcinoma
Squamous cell cancer Oncology A malignant epithelial neoplasm that arises in squamous cells of skin, hollow organs, respiratory and GI mucosa, either de novo or in actinic keratosis, or other lesions; SCCs have a
high cure rate if treated early; 90+% occur on skin regularly exposed to sunlight or other UV radiation; SCC is more common in Pts with a genetic predisposition, especially those with light skin–↓ melanin in skin and eyes, exposure to
chemicals, radiation, arsenic–present in some herbicides; SCC is more aggressive than BCC and carries a slight risk of metastasis if untreated for a long period of time Clinical Asymptomatic early, pain if ulcerated. See Actinic keratosis, Basal cell carcinoma, Skin cancer.
Patient discussion about Squamous carcinoma.
Q. what is the most accurate pathological test to identify the primary source of a cystic mass in the neck? the mass was removed. Pathologist was unable to identify the source and diagnosed the mass as a branchilogic carcinmoa (which is extremely rare, if exists at all). Therefore, I am looking for the most updated test and examinations that can be applied to blocks of the mass and determine their origin (primary source)
A. Pathologic examinaions under a microscope are the most accurate ones there are, and sometimes even they don't help to identify the cell types. I do not have any other ideas on other tests you can do, and I believe you should follow the treatment your doctors will advise you based on this diagnosis they have made.
