Proliferating systematized angioendotheliomatosis of a 5-month-old infant

Proliferating systematized angioendotheliomatosis occurred in a 5-month-old infant and persisted for five months. On the basis of the clinical course and the results of histological examination, the inflammatory type of proliferating angioendotheliomatosis was found. The condition is characterized by the proliferating reaction of the vascular endothelium owing to an allergic process as a result of immunological mechanisms by bacterial infection or protein of cow's milk in this uncommon disease.
