Pyogenic Granuloma: History, Clinical and histological features (Pregnancy tumor), DD & Treatment 

Pyogenic granuloma represents an exuberant CT proliferation to a known stimulus or injury. The term pyogenic granuloma is a misnomer in that it is not pus producing, and it does not represent granulomatous inflammation. Hormonal changes of pregnancy modify the gingival reparative response to injury, producing what was once called a "pregnancy tumor." Pyogenic granulomas as typically red, pedunculated or sessile and may range in size from a few millimeters to several centimeters. Microscopically, they are composed of lobular masses of hyperplastic granulation tissue. Clinically, this lesion is similar to peripheral giant cell granuloma, peripheral odontogenic or ossifying fibroma and rarely metastatic carcinoma. Pyogenic granulomas should be surgically excised along with removal of etiological factors
