Vulvar cancer is a malignancy of female lower genital tract with incidence of 1:100,000 in Poland. The most common types of vulvar cancers are squamous cell carcinoma and basal cell carcinoma. This study was approved by the board of the Clinical Unit of Obstetrics, Women’s Disease and Gynecological Oncology, United District Hospital, Collegium Medicum University of Nicolaus Copernicus in Toruń, Poland. This is a tertiary reference center. We analyzed cases of postmenopausal women diagnosed with vulvar cancer referred to our clinic for surgery. The aim of the study was to compare 48 MHz ultrasound images of vulvar cancer with histological images and assess the utility of high-frequency ultrasonography images in preoperative assessment. We examined 3 cases of squamous cell carcinoma and 1 case of basal cell carcinoma using 48 MHz DermaView high-frequency mechanical probe. We described typical ultrasonographic features of vulvar carcinoma, such as echogenicity, depth of infiltration, as well as we discussed limitations of this transducer. The 48 MHz frequency exhibits a promising value for the preoperative assessment of vulvar carcinoma. High-frequency ultrasonography can provide some important information, such as morphology, boundary, internal echo, and thus help choose adequate surgical approach.
