Pleuropulmonary blastoma (PPB) is among the rarest malignant tumors diagnosed in children. PPBs can be histopathologically classified into 3 types: cystic tumor (type I), mixed cystic and solid tumor (type II), and pure solid tumor (type III). We describe a case of type III PPB that was detected in a prenatal fetus, confirmed using histopathological methods. To the best of our knowledge, this is the first case describing a type III PPB detected in a fetus. Prenatal ultrasonography is an excellent tool for detecting pulmonary lesions during the diagnostic phase, and the possibility of PPB should be considered when solid tumors are detected. Early detection can allow for the performance of full resection, leading to a better prognosis for this cancerous tumor.
