Basal cell carcinoma is a malignant tumor that rarely metastasizes. It is composed

of cells that arise from the epidermis and the appendages which resemble the basal layer of the epidermis and is associated with a characteristic stroma. It tends to grow slowly and invade locally over many years, which eventually leads to ulceration, hence the name “rodent ulcer.”

BASAL CELL CARCINOMA Definition

Слайд 7

Basal cell carcinomas account for more than 75% of keratinocytic skin cancers diagnosed

in the United States each year. The incidence of basal cell carcinoma varies from 422 per 100,000 general population in Kauai, Hawaii, to 146 per 100,000 in Rochester, Minnesota. The average annual incidence in the United States is 191 per 100,000 white persons. It is the most common form of skin cancer in whites. It is very rare in darkly pigmented people. It most frequently occurs in persons older than 40 years of age. The frequency is slightly higher in males. Other risk factors include geographic locations with high solar intensity, exposures to inorganic trivalent arsenic, ionizing radiation, and immunosuppression.

Слайд 14

Squamous cell carcinoma is a malignant tumor arising from epidermal or appendageal

keratinocytes or from the squamous mucosal epithelium. There is often a history of damage by exogenous agents acting as carcinogens, such as sunlight, ionizing radiation, local irritants, or arsenic ingestion. The tumor cells have a tendency toward keratin formation.

Слайд 19

Malignant melanoma of skin accounts for 160,000 new cases annually, with slightly

more occurring in women than in men (M:F sex ratio, 0.97). It is a tumor particularly common in White populations living in sunny climates. High rates of incidence are found in Australia/New Zealand, North America, and northern Europe
