Vascular Transformation of Sinuses in Cervical Lymph Node

ABSTRACT

Vascular transformation of lymph node sinuses is a rare condition and only isolated cases have been reported in the literature. Most lymph nodes with vascular transformation of sinuses are found in abdomen, and head and neck involvement is rare. It is characterized by the intrasinusoidal proliferation of endothelial cells forming a system of anastomosed channels filled with blood, and by an intrasinusoidal fibrous reaction. It is important to recognize that they may be a marker for the presence of any undetected malignant tumor. In this article, we report a rare case of vascular transformation of cervical lymph node sinuses with some reviews of the literature.
