The role of ultrasound examination for early identification of lymph-node metastasis of cutaneous squamous cell carcinoma: results from a single institutional center

Metastasis from cutaneous squamous cell carcinoma (cSCC) mainly involve the regional nodal basin, with an incidence ranging from 2%-4% until 15% in case of high-risk tumors. When dealing with high-risk cSCC, ultrasound examination is recommended every 3- 4 months during follow up. We aimed to determine the role of US examination in the early diagnosis of nodal metastasis from cSCC.
