I also thought of intravascular PG. SMA stains the pericytes but the endothelial cells are negative. Besides the lobular pattern with capillaries is typical of PG.

Looking at picture 1 again, the lesion appears intravascular, which I missed at first glance. Agree with intravascular pyogenic granuloma.

Intravascular pyogenic granuloma.
The SMA stain nicely highlights the circumferentially oriented smooth muscle fascicles of the parent vessel wall.

Yes, this is an intravascular PG (lobular hemangioma). It's an uncommon presentation of a common lesion.
