The role of ultrasonography in head and neck Non-Melanoma Skin Cancer approach: an update with a review of the literature

Abstract

Non-Melanoma Skin Cancer is one of the most common cancer types and the face is the most affected region. The diagnosis of the skin cancer relies on clinical inspection, palpation, dermoscopy followed by incisional or excisional biopsy. When skin cancers are removed from the face, many factors are involved, including aesthetics. In addition, surgical planning with preoperative acknowledgement of the tumour margins is often the key to avoid incomplete excision, the need for reintervention, or in the prevention of functional and aesthetical defects in the treatment of skin tumours. In recent years, the development of new technologies in sonography, including high frequencies transducers can provide a full range of data. It can offer valuable information regarding the size of the tumour including the depth of invasion, the extent of the tumour, histology and subtypes of the lesions which are helpful for the treatment plan. It also may be efficient in detection of positive margins after surgery and it could play a role in the treatment of skin cancer, prevention of local recurrences and overall control of the disease. K
