UNASSIGNED: @entity5 , also known as @entity1377 ( @entity1377 ), is a locally aggressive hemangiendothelioma characterized by intravascular papillary proliferations of atypical endothelial cells. Besides @entity1377 , papillary tufts lined by hobnail endothelial cells have been rarely described in vascular proliferations. We report two cases of acquired @entity2695 , which focally showed this finding. We present a 15-year-old male and a 7-year-old @entity1 with erythematous nodules. Both lesions were composed of capillary lobules intermingled with large sinusoidal spaces lined with a single layer of flat endothelial cells, which focally developed intravascular papillary proliferations lined by plump hyperchromatic endothelial cells and a central connective tissue core. Both types of cells were positive with @entity2279 and ERG and negative for @entity14600 , @entity18262 and podoplanin. @entity3969 1 marker was strongly positive in the @entity8702 areas while negative in the intravascular tufts. Both lesions recurred after the first excision but we did not observe further recurrence or evidence of @entity3 in the follow-up. In summary, our cases expand the histopathologic findings that may be seen in conventional acquired @entity8702 . The focal presence of dabskoid tufts within an otherwise conventional @entity8702 should be not misinterpreted as evidence of @entity5 .
