Malignant MGCT in a 20-year-old man with left chest pain. (a) Posteroanterior chest radiograph shows pulmonary metastases. Testicular US was performed to look for a primary neoplasm. (b) Gray-scale US image of the left testis shows an ill-defined heterogeneous mass with cystic spaces (white arrow) and calcifications (black arrow). (c) Photograph of the gross pathology specimen shows a variegated appearance (arrow) secondary to the heterogeneity of the tumor, which explains the heterogeneous US appearance.
