Congenital retiform hemangioendothelioma

OpenAlex es

Background: Retiform hemangioendothelioma (RH) is an extremely rare and distinct variant of low-grade, well-differentiated cutaneous angiosarcoma seen in young adults and is characterized by a high recurrence rate, but low metastatic potential. To the best of our knowledge, this is the first report of the congenital RH. The lesion was treated by wide surgical resection. Biopsy revealed RH. We herein describe a congenital case of this rare vascular tumor, arising on the left foot, which was diagnosed when the patient was 21 years old. Results and Conclusions: There was no recurrence or lymph node metastasis during a follow-up period of 6 months. The authors expand the concept of RH by adding a congenital case.
