Background:Gestational trophoblastic disease (GTD) adversely affects pregnancy by the development of Hydatidiform mole and placental site gestational tumor. GTD is a discrete pool of epidemiological and clinicopathological entities. Therefore, every geographical region should be studied separately. The Indian subcontinent is under-reported for this disease. This paper analyses the data from a large hospital.Material/Methods:92 patients with GTD were analyzed in the period from 1995 to 1999.Results:The incidence of GTD was 1.31 per 1000 live births and one per 967 pregnancies irrespective of outcome. 93.5% of the patients had moderate to severe vaginal bleeding as presenting symptom, while routine antenatal ultrasonography revealed GTD in 6.5% completely asymptomatic patients. Among the major risk factors were age over 30 (p=6.3 x 10[sup]–3[/sup], RR=2.7), previous abortion (p
