A patient with endovascular papillary angioendothelioma with a low grade of malignancy showing papillary proliferation of endothellold cells Is presented. The patient, an 83‐year‐old woman, underwent resection of a tumor of the neck. At operation a 9×7 cm cystic tumor containing yellow transparent liquid with clots was found In the subcutaneous tissue. Histological studies showed endotheliold cells with spindle‐shaped nuclei proliferated in layers around the fibrovascular cores, which showed the characteristic appearance of papillary proliferation. These cells were Immunohlstochemlcally positive for CD31, CD34 and factor VIII‐related antigen. Based on these observations, the tumor was considered to be an endovascular papillary angioendothelioma (Dabska tumor). Dabska tumor Is a vascular tumor with a low grade of malignancy and usually occurs in infants and young children. About 13 cases of Dabska tumor have been reported. The occurrence of a Dabska tumor In an aged patient is considered to be rare.
