Importance of sentinel lymphatic node biopsy in detection of early micrometastases in patients with cutaneous squamous cell carcinoma

Cutaneous squamous cell carcinoma (CSCC) is the second most common malignant skin cancer with a tendency to spread via lymphogenic pathway. Metastases are found in 2% - 6 % of cases. The aim of this study was to determine CSCC micrometastases when non-invasive examination methods do not detect them.
