Basal cell carcinoma: what dentists need to know.

BACKGROUND: Basal cell carcinoma, or BCC, is a malignant epithelial tumor of the skin, commonly seen in the head and neck. Because dentists routinely evaluate the head and neck, the authors present three examples of BCC of the face and jaw to help clinicians recognize the condition. They also provide a literature review regarding BCC's etiology, classification, treatment and prevention. DESCRIPTION OF THE DISEASE: Sun exposure plays an important role in the development of BCC. The most susceptible people are those with minimal skin pigmentation. BCC is more frequently seen in men than in women. The most common form of BCC is the nodular type, which, if untreated, eventually ulcerates and may result in extensive local tissue destruction. The three cases described in this article highlight the range of BCC severity. CLINICAL IMPLICATIONS: Oral health care providers may play an important role in the recognition and diagnosis of BCC involving the head and neck. Early recognition and diagnosis may lead to management that results in improved cure rates, with reduced morbidity and reduced treatment costs.
