Lymph node dissection in malignant melanoma

Regional node dissection was performed in 120 patients with malignant melanoma. Patients with clinically negative nodes had a 90% survival, whereas patients with enlarged nodes had a 15% survival. In 45 inguinal dissections, usually associated with a high morbidity, there was only a 4.5% incidence of infection and a 6.5% incidence of skin edge necrosis. For all types of node dissection, the overall incidence of wound infection was 5.8%, and that of necrosis of skin edges was 5%.
