Abstract
|
|
|
Lobular capillary hemangioma, so-called pyogenic granuloma, is a relatively common mucocutaneous vascular neoplasm that commonly occurs in skin. Intravenous lobular capillary hemangioma is an unusual variant that usually occurs in the neck and upper extremities. We have experienced a case of intravenous lobular capillary hemangioma. The patient was a 19-year-old female who had a soft, nontender neck mass, 0.8 cm x 0.7 cm, in the medial side of left
sternocleidomastoid muscle for a month. The clinical impression was lymphadenitis. On gross examination, the tumor was pale pink to gray and nodular. Microscopically, the tumor showed typical patterns of lobular capillary hemangioma, however, they arose from the vessel wall and protruded into the vessel lumen. By immunohistochemistry, the tumor cells and surrounding vascular walls were positive for CD31 and smooth muscle actin. The pathologic finding and the
differential diagnosis are discussed.
