Lymphatic transport and phagocytosis of melanosomes in blue nevus

Abstract

The present paper describes ultrastructural aspect of lymphatic transport of dermal melanosomes in blue nevus. At least two processes may be responsible for the transport across the lymphatic endothelial wall in vivo; one is the passage of melanophages through the intercellular junctions and the another of free melanosomes. Phagocytosis of melanosomes by lymphatic endothelial cells is discussed.
