Ultrasound-guided FNA cytology of groin lymph nodes improves the management of squamous cell carcinoma of the vulva: Results from a comparative cytohistological study.

FNAC of suspicious lymph nodes represents a useful tool in the management of patients with vulvar cancer. A positive result enables the surgeon to immediately perform a bilateral inguinofemoral lymphadenectomy thus avoiding an unnecessary sentinel lymph node sampling. Finally, FNAC can also predict the presence and extent of metastatic disease in other surgically resected inguinofemoral lymph nodes.
