(carcinoma, squamous cell, malignant) A malignant neoplasm arising from squamous epithelial cells.

A carcinoma arising from squamous epithelial cells. Morphologically, it is characterized by the proliferation of atypical, often pleomorphic squamous cells. Squamous cell carcinomas are graded by the degree of cellular differentiation as well, moderately, or poorly differentiated. Well differentiated carcinomas are usually associated with keratin production and the presence of intercellular bridges between adjacent cells. Representative examples are lung squamous cell carcinoma, skin squamous cell carcinoma, and cervical squamous cell carcinoma.

Cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. Squamous cells are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the passages of the respiratory and digestive tracts.

Carcinoma developed from squamous epithelium.

The presence of squamous cell carcinoma of the skin.

(carcinoma, squamous cell) A carcinoma derived from stratified SQUAMOUS EPITHELIAL CELLS. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)

Squamous cell carcinoma is a malignant tumor of epidermal keratinocytes that invades the dermis; this cancer usually occurs in sun-exposed areas. Local destruction may be extensive, and metastases occur in advanced stages. Diagnosis is by biopsy. Treatment depends on the tumor�s characteristics and may involve curettage and...

Squamous cell carcinoma (SCC) is the second most common skin cancer. SCC most often affects individuals who are exposed to large amounts of sunlight. It is typically characterized by a red papule or plaque with a scaly or crusted surface; it may be suspected whenever a small, firm reddish-colored skin lesion, growth or bump appears on...

Cutaneous squamous cell carcinoma (SCC) is the proliferation of atypical, transformed keratinocytes in the skin with malignant behavior. It ranges from in situ tumors (also known as Bowen disease) to invasive tumors and metastatic disease.Precursor lesions for SCCs are called actinic (or sun-damage) keratosis; this topic is covered in...
