Lymphovascular Invasion and the Decision for Postmastectomy Radiation Therapy: A Cautionary Case Report

Abstract

Summary:. Breast reconstruction is frequently adversely affected by postmastectomy radiation therapy. Some radiation therapists recommend postmastectomy radiation therapy based on the finding of lymphovascular invasion in the context of other findings. However, the diagnosis of lymphovascular invasion varies between pathologists and institutions. Sometimes special endothelial cell stains and outside opinions are necessary for the decision for postmastectomy radiation therapy. This case report illustrates the variation in the diagnosis of lymphovascular invasion. Plastic surgeons must remain current on the standard indications for postmastectomy radiation therapy and on the basic findings of lymphovascular invasion.
