title: Pulmonary blastoma metastatic to the ovary.
abstract: Pulmonary blastoma (PB) is a rare and aggressive pulmonary malignancy. A 38-year-old woman was diagnosed as biphasic PB (1 subgroup of sarcomatoid carcinoma) and treated by surgery, radiotherapy, and chemotherapy. Six months later, the patient presented with menstrual disorder and a mass in the abdominal-pelvic cavity. Abdominal hysterectomy and bilateral salpingo-oophorectomy showed the morphology of metastatic PB in both ovaries. The metastatic tumor was composed exclusively of epithelial components resembling well-differentiated fetal adenocarcinoma. To our knowledge, this is the first reported case of bilateral ovarian metastasis from biphasic PB.
