- Abstract
Background According to the International Society for the study of vascular Anomalies, vascular anomalies are classified as vascular neoplasms and vascular malformations. In some vascular lesions, categorization as a neoplasm or malformation has not been established with confidence so far. In order to further clarify the nosology of verrucous hemangioma, we studied 13 cases. Objective To analyze immunohistochemical characteristics of verrucous hemangiomas in order to gain further insight in its histogenesis. Methods We carried out a retrospective review. Immunohistochemical expression for Wilms tumor 1 ( WT1), Glut-1 and D2-40 was performed in 13 cases. Results Immunohistochemistry performed with Glut-1 and WT1 showed positive staining in all lesions. All verrucous hemangiomas lacked D2-40 immunostaining. Conclusions This is the first report in the literature investigating WT1 in verrucous hemangioma in order to further clarify the nosology of this vascular anomaly. Despite the clinical features of verrucous hemangioma, which are similar to those seen in vascular malformations, verrucous hemangioma exhibited an immunoprofile similar to vascular neoplasms, according to WT1 and Glut-1 positivity.
