Abstract:  We report a young boy with a malignant tumor, which remained unrecognized for 8 months because it was assumed to be a hemangioma. The presentation of a rhabdoid tumor mimicking hemangioma is very rare. It was reported only on two earlier occasions. Rhabdoid tumors are one of the most aggressive types of malignancies encountered in pediatric oncology. It is important to recognize that a fast growing vascular lesion in a child will often be a hemangioma, but could also be an aggressive tumor.
