Radial Hyperkeratosis & Squamous Cell Carcinoma
Radial Hyperkeratosis: They are hyperkeratotic lesions that < strong>can develop into malignant ones. They are due to the long-term cumulative effect of solar radiation on the keratinocytes. The probability of occurrence after 40 increases with age and they are found in people with skin type I and II. Depending on the location and after some years some can develop into squamous cell carcinoma.
Squamous cell carcinoma: It is a primary malignant neoplasm of the skin due to the mutation of the keratinocytes of the skin or mucous membranes. It is the second most common skin cancer. Primary squamous cell carcinomas occur in sun-exposed areas and are due to the long-term damaging effect of radiation.
Basal cell carcinoma: It is the most common malignant neoplasm of the skin and causes local tissue destruction. It grows slowly. It usually occurs after the age of 40 and more often in people with skin type I and II. It is associated with the patient’s intermittent exposure (vacation, sunburn, childhood) to the sun and ionizing radiation.
