According to clinical history, this must be atypical vascular proliferation due to radiotherapy.
DDx well differentiated angiosarcoma.

Structurally, it is similar to a targetoid hemosiderotic hemangioma; but, in this context, it could be a mimic of that condition -- really an example of low-grade angiosarcoma. My understanding is that MYC by IHC might be of value in a lesion like this.

I’d call this benign acquired vascular proliferation in previously irradiated skin. I didn’t find worrying features for radiation-induced cutaneous angiosarcoma, like interanastomosing vessels lined by multilayered endothelium, involvement of the subcutaneous fat, and large dimensions.

Agree, atypical vascular proliferation secondary to radiotherapy.

Atypical vascular proliferation. MYC would have been helpful, but was not done. As it turns out, this was a papular lesion, and was completely excised, more than 3 years ago. Since then, she has remained disease free.
