Pregnancy granuloma occurs in 5% of pregnant women. It is indistinguishable from pyogenic granuloma, and is a rapidly growing, tumor-like lesion that develops as a response to local irritation such as poor hygiene, overhanging restorations, or trauma. Increasing estrogen and progesterone levels during pregnancy exacerbate the condition.
