In Retiform hemangioendothelioma there is usually a lymphocytic infiltrate associated with the proliferating rete testis like vessels. Nonetheless I think this is a Retiform Hemangioendothelioma

I’m leaning toward hobnail hemangioma, although don’t see hemosiderin.  Don’t think Kaposi sarcoma but if clinically suspicious  would do hhv8 immunostain.

If it's in an inner organ or extracutaneous sites, i would suggest anastomosing hemangioma. Otherwise, I would probably go for retiform HE because that fits the best. But if it's a small lesion, i might call it anastomosing hemangioma, a recently described  hemangioma. Anastomosing hemangioma just sounds the best for this lesion.

I thought more of microvenular hemangioma (if lesion clinically small), hobnail hemangioma another good option but less likely. AML could help if it shows a complete and continuous layer of pericytes (frequently seen in benign lesions and particularly in microvenular hemangioma). Histologically I do not see sings of malignancy, bu again clinicopathlogical correlation is mandatory
