[Retiform hemangioendotelioma in a 8-year-old girl--case report].
Retiform hemangioendothelioma (RHE) is a rare vascular tumoriform lesion characterized by rete testis--like vascular structures. RHE belongs to a group of vascular tumors of intermediate malignancy and together with Dabska tumor form a category of so-called hobnail hemangioendotheliomas. Authors present a case of a 8-year-old girl with RHE which was located in right calf and measured 12 x 8 mm. Histologically, the tumor consisted of a net of vessel formations with retiform appearance and prominent endothelial nuclei. Some of vascular channels had intraluminal projections. Other benign and malignant vascular lesions with hobnail cells (hemangioma, angiosarcoma) have to be considered in differential diagnosis.
