March 4th 2011 17:05
Basal cell carcinoma is the commonest form of skin cancer. Although classified as a malignant tumour it grows very slowly. It usually occurs on the central area of the face especially in fair skinned people . The prevalence increases greatly with exposure to sunlight. It is a tumour of low degree of malignancy and is locally aggressive. This tumour is also known as "Rodent Ulcer". If the tumour is untreated it may infiltrate into the tissue and penetrate deep into the bone and cause ulceration. Basal cell carcinoma may recur after excision. Very rarely metastasis may occur. Basal cell carcinoma may be associated with: i) Previous scarring or trauma ; ii) Pre-existing skin condition ; iii) Rare syndrome - Naevoid Basal Cell Carcinoma Syndrome.
