Splenic myoid angioendothelioma mimicking metastatic disease in an 8-year-old with Stage IV Wilms' tumour.

Myoid angioendothelioma are rare and benign vascular tumours of the spleen. Radiographic evaluation and diagnosis is often challenging and subjecting tissue samples to immuhistochemical analysis is often required to make a definitive diagnosis. Myoidangioendotheliomas can be managed with open or laparoscopic splenectomy with minimal risk of recurrent disease. Herein, we present a case of a myoid angioendothelioma in a patient with stage IV Wilms' tumour.
