Abstract |
Anomalous marginal veins of the trunk or extremities are congenitally incompetent entities found in association with phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)-related overgrowth syndromes, such as Klippel-Trénaunay syndrome and congenital lipomatous overgrowth, vascular malformations, epidermal nevi, and skeletal deformities ( CLOVES) syndrome. When present, they can be a major source of venous hypertension-related morbidity and potentially lethal thromboembolic events. Herein, we describe a rare case of an upper extremity marginal vein in a patient with CLOVES syndrome. Through a multimodal therapeutic approach, we identified a somatic PIK3CA mutation in the excised anomalous vein. This finding questions the validity of commonly employed terminology, such as persistent embryonic vein, in reference to these anomalous entities.
