Abstract:
Endovascular papillary angioendothelioma (EPA) is a rare vascular tumor of low grade malignancy, encountered primarily in children. However some cases have also been reported in adults. A sixty year old female with EPA is described here. She presented with a swelling in the neck. Total surgical excision was performed. Histomorphology revealed anastomosing lymphatic channels showing intraluminal papillary fronds with hyaline vascular cores and hobnailing of endothelial cells. A diagnosis of EPA was made based on this picture. This tumor is recurrent and nodal metastasis has been reported in some cases.
