basal cell carcinoma the most common form of skin cancer, consisting of an epithelial tumor of the skin originating from neoplastic differentiation of basal cells, rarely metastatic but locally invasive and aggressive. It usually occurs as small pearly nodules or plaques on the face of an older adult, particularly on a sun-exposed area of someone with fair skin. It has been divided into numerous subtypes on the basis of clinical and histological characteristics.

small cell carcinoma a common, highly malignant form of bronchogenic carcinoma in the wall of a major bronchus, occurring mainly in middle-aged individuals with a history of tobacco smoking; it is radiosensitive and has small oval undifferentiated cells. Metastasis to the hilum and to mediastinal lymph nodes is common.
spindle cell carcinoma squamous cell carcinoma marked by development of rapidly proliferating spindle cells.
squamous cell carcinoma
1. carcinoma developed from squamous epithelium, having cuboid cells and characterized by keratinization. Initially local and superficial, the lesion may later invade and metastasize.
2. the form occurring in the skin, usually originating in sun-damaged areas or preexisting lesions.
3. in the lung, one of the most common types of bronchogenic carcinoma, generally forming polypoid or sessile masses that obstruct the airways of the bronchi. It usually occurs in middle-aged individuals with a history of smoking. There is frequent invasion of blood and lymphatic vessels with metastasis to regional lymph nodes and other sites. Called also epidermoid carcinoma.
transitional cell carcinoma a malignant tumor arising from a transitional type of stratified epithelium, usually affecting the urinary bladder.
1. a variety of squamous cell carcinoma that has a predilection for the buccal mucosa but also affects other oral soft tissue and the larynx. It is slow-growing and somewhat invasive.
2. Buschke-Löwenstein tumor, so called because it is histologically similar to the oral lesion.

carcinoma of skin
squamous cell carcinomas occur on the third eyelid, cornea or the eyelid of cattle and horses, on the penis and prepuce of horses, from the mucosa of the frontal sinus to invade the horn core of cattle (called also horn cancer), on the ears of sheep, on the vulva of ewes when the tail is docked too short. In goats the ears, udder, base of the horn and perineum are also susceptible sites. The tumors grow rapidly, show considerable invasiveness and often metastasize to local lymph nodes. In dogs and cats, squamous cell carcinomas are common, particularly on the face and pinnae of white cats. See also squamous cell carcinoma (below).

squamous cell carcinomas occur in the stomach of the horse and the bovine rumen. The associated clinical syndrome in the horse is one of indigestion and weight loss. Metastasis occurs commonly. In cows there may be vagus indigestion or chronic tympany of the rumen.
