Sustained Remission following Lung Resection of Isolated Pulmonary Stage III Epithelioid Trophoblastic Tumor: A Case Report

ETTs are among the rarest forms of GTD. ETT rarely presents outside the uterus and often demonstrates poor response to chemotherapy. This case report highlights a unique presentation of primary pulmonary ETT, successfully managed with surgical resection alone, achieving sustained remission without chemotherapy. In women of reproductive age with persistently elevated β-HCG levels of unclear origin, ETT should remain a consideration. While surgical management may be a viable treatment option for tumors with sole site metastasis, close postoperative monitoring is essential.
