Malignant endovascular papillary angioendothelioma is a rare childhood vascular tumor. This case highlights its presentation with Kasabach-Merritt syndrome in a boy with angiomatosis.

Area of Science:

  • Vascular Oncology
  • Pediatric Pathology

Background:

  • Malignant endovascular papillary angioendothelioma (Dabski tumor) is a rare vascular neoplasm.
  • Typically observed in pediatric patients, it features endothelial cell proliferation within vessels.

Observation:

  • A rare case of this tumor is presented in a young boy with pre-existing angiomatosis.
  • The tumor manifested as an ulcerated lesion superimposed on a buttock vascular malformation.
  • The patient developed Kasabach-Merritt syndrome.

Findings:

  • The case illustrates the complex presentation of malignant endovascular papillary angioendothelioma.
  • Co-occurrence with angiomatosis and Kasabach-Merritt syndrome is detailed.
  • The tumor's evolution on a pre-existing vascular malformation is described.
