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.

Key Words: Intravenous lobular capillary hemangioma, pyogenic granuloma
