미세소정맥 혈관종 2예

Abstract

Microvenular hemangioma (MH) is a recently described, uncommon, acquired vascular, tumor presenting clinically as a small reddish nodule in young and middle, aged individuals of either gender. Histologically, thin and irreguarly branching small venules with inconspicouous lumia and without cellular atypia are found widely throughout the dermis. The presence of histologic features of the collagen dissection and vascular tufts makes it necessary to differentiate MH with Kaposi`s sarcoma and angioblastoma. As we are aware, the description of these two cases which showed the characteristic clinical and histologic features of MH, is the first report of MH in Korea.
