Ultrasound semiotics of cutaneous melanoma metastases in soft tissues and lymph nodes

In the presented study, ultrasound semiotics of cutaneous melanoma metastases in soft tissues and lymph nodes has been analyzed in 110 patients. Echography was performed on ultrasound Sonoline Antares (Siemens) equipment using linear 4-13 MHz transducers. Verification was done on the basis of aspiration biopsy and/or histological findings. Clinically invisible metastases were found in 35 % of cases. Ultrasonically, metastases were identified as a foreign tissue of low echogenicity against the background of the normal structure of the skin and soft tissues.
