title: Mesothelial Cells Within Vascular Transformation of Mediastinal Lymph Node Sinuses: An Unusual Benign Collision Mimicking Colliding Malignancies.
abstract: Vascular transformation of lymph node sinuses represents a rare benign entity mimicking malignant counterparts such as nodal Kaposi sarcoma. The presence of mildly atypical benign mesothelial cells within nodal sinuses raises the possibility of metastatic malignancy. Herein, a rare case of vascular transformation of lymph node sinuses with reactive sinusoidal mesothelial cells is outlined as a unique benign pathology and a potential mimicker of a malignant collision tumor.
