The Histopathological Spectrum of Pyogenic Granuloma: A Case Series

Table 2

Histopathological differences between LCH and non-LCH type of pyogenic granuloma.

LCH type of pyogenic granuloma	Non-LCH type of pyogenic granuloma
Vessels in lobular aggregates	No aggregation, focal fibrous tissue
Proliferating blood vessels	Vascular core resembling granulation tissue
Small luminal diameter	Larger luminal diameter
Perivascular mesenchymal cells SMA positive	Perivascular mesenchymal cells, SMA negative

LCH: lobular capillary hemangioma; non-LCH: non-lobular capillary hemangioma; SMA: -smooth muscle actin.
