Diagnosing basal cell carcinoma: what is the role for dermoscopy?
Dermoscopy has a role in the diagnosis of basal cell carcinoma (BCC) and may give clues to discern between superficial BCCs and other subtypes. Histopathology, however, remains the gold standard for diagnosis of these common skin cancers.
Basal cell carcinoma (BCC) is the most common form of skin cancer. Chronic sun exposure appears to be the most important risk factor but there are others, such as fair skin phototype, that play an important role. BCCs usually develop on skin that contains pilosebaceous units, most commonly on the face, but the lesions also occur on locations that are not exposed to the sun. Although it rarely metastasises, a BCC may be locally aggressive and lead to serious morbidity if not correctly diagnosed and treated.
