Multicentric epithelioid hemangioendothelioma involving the lungs, trachea, liver and skeletal muscles
Epithelioid hemangioendothelioma (EH) is a rare benign vascular tumor, which typically present as multinodular lesions that can involve one organ or more. We report a 12 years old female who presented with one-year history of progressive intolerance to physical activity and 3 months history of dry cough and weight loss. Physical examination was positive for diminished breath sounds and crackles of right hemithorax, and small mass in abdominal wall. CT of chest and abdomen revealed multiple nodular lesions in both lungs, liver, and right abdominal rectal muscle. Bronchoscopy showed multiple small tracheal lesions. Immunhistochemical staining of biopsy specimens obtained from the trachea, liver and muscle was consistent with EH.
