Lymphatic Mapping to the Inguinal Region in Patients with Lower Extremity Melanoma Undergoing Radical Inguinal Lymph Node Dissection: A Retrospective Cohort Study

Background/Objectives: The anatomical distribution of inguinal lymph node (ILN) metastases may inform research on the extent of therapeutic dissection for lower-limb melanoma.

Methods

Fifty-eight patients undergoing radical inguinal lymph node dissection (rILND) were retrospectively evaluated using five anatomical zones. Zone-specific node counts were reaggregated, and exploratory binary logistic regression assessed multiple-zone involvement.
