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.
