Indian Journal of Pathology & Microbiology. 2009 Apr-Jun; 52(2): 240-1http://imsear.searo.who.int/handle/123456789/73170Placental site nodule is an uncommon, benign, generally asymptomatic lesion of trophoblastic origin, which may often be detected several months to years after the pregnancy from which it resulted. This entity may have bizarre histologic findings and should be distinguished from other aggressive lesions like placental site trophoblastic tumor, epithelioid trophoblastic tumor and squamous cell carcinoma.engJournal Article
