Tufted angioma. It is nice to see the proliferative nodules inside the vascular spaces negative for D2-40.

With some delay, to say the least, happy new hear from Italy! I would go for tufted hemangioma. There are some nice crescentic spaces.

Agree with Eman El-Nabarawy. The presence of lymphatic channels (positive with D2-40) around the lobules is the distinctive feature of Tufted Angioma.

[font=Arial, sans-serif][size=2]Tufted angioma and kaposiform hemangioendothelioma are vascular tumors of the same neoplastic spectrum. Kaposiform hemangioendothelioma may have tufted angioma like areas. I think the D2-40 pattern of staining, disclosing a predominance of spindle cells at the periphery of the cannonballs, is more in keeping with kaposiform hemangioendotelioma. In tufted angioma the positivity should be limited to dilated vesssels present in the stroma and in the cannonballs and, at most, in some of the slit-like capillaries in the cannonballs.[/size][/font]

The cannonball-like vascular lobules are small and well circumscribed, and the expression of D2-40 around, not inside, the vascular lobules are characteristics that make me favor tufted angioma. Patient should be screened for Kasabach-Merritt syndrome.
