Various benign and malignant tumors may arise from the skin. These may be of epidermal, dermal, subcutaneous or appendageal origin. Skin biopsy is the gold standard for diagnosis of skin tumors. There is paucity of published data on the role of imaging modalities in diagnosis of skin tumors. High-frequency ultrasonography (7–50 MHz) is a potential non-invasive, objective modality which can be utilized in the diagnosis and localization of skin tumors. It provides valuable information about the tumor characteristics such as size, shape, depth, consistency and vascularity before invasive skin biopsy or surgery is planned. Sentinel lymph nodes in malignant melanoma can be well visualized and studied by this technique. It is also a good modality to detect local recurrence of tumors during post-operative follow up, especially those with a high likelihood of local recurrence or lesions excised with inadequate margins. High-frequency ultrasonography is additive to clinical diagnosis and can be considered a useful non-invasive method to plan the management of various skin tumors and is of prognostic value in some cases.
