Aim The aim of this case report is to present a case of rapidly growing large pregnancy tumor which did not regress even after parturition. Introduction Pyogenic granuloma is a commonly occurring benign inflammatory hyperplasia of the skin and oral mucosa. It usually arises in response to nonspecific infection as sessile or pedunculated, erythematous, exophytic papule or nodule with a smooth or lobulated surface that bleeds easily. Pyogenic granuloma occurring during the pregnancy is called as pregnancy tumor. Case report In this case report, a rapidly growing pregnancy tumor in a 23-year-old female is described and the clinical features, histopathologic features and management of the lesion are discussed. Pregnancy tumor rarely reaches 2 cm in size, however in our case the lesion had enlarged to an extent that it was interfering with occlusion (3 × 2 cm). Even after parturition the enlargement showed no regression in size, so the lesion was surgically excised. Conclusion Lack of awareness among pregnant patients about oral health care during pregnancy results in occurrence of various oral lesions which challenges the dentist and gynecologist in providing proper treatment. Hence creating oral health care awareness among such patients is of utmost importance. Clinical significance The prenatal oral health check-up and counselling is important in preventing the occurrence of various oral lesions during pregnancy.
