Pregnancy tumor mimicking a neoplasm--A case report.

Pregnancy brings about a complex series of physiological changes for women. A tumor-like gingival enlargement can occur during pregnancy. The size of the tumor generally increases gradually over a few months as the pregnancy progresses, then shrinks spontaneously after delivery. This case report describes a case of gingival swelling in a 26-year-old woman at five months of gestation. The lesion was not painful and grew very rapidly over a three-week period. The histopathological examination revealed granulation tissue with non-neoplastic proliferation of endothelial cells, suggestive of pregnancy tumor.
