A pregnant patient presents with a lobulated, vascular, easily bleeding gingival mass. What is this lesion most specifically called, given her pregnancy?

This lesion is histologically a pyogenic granuloma; when it occurs specifically during pregnancy (attributed to hormonal influences exaggerating the vascular/inflammatory reactive response to local irritation), it's given the more specific name 'pregnancy tumor' or 'granuloma gravidarum.' Outside of pregnancy, the same lesion is simply called a pyogenic granuloma.
