Figure 3From: Testicular fusocellular rhabdomyosarcoma as a metastasis of elbow sclerosing rhabdomyosarcoma: A clinicopathologic, immunohistochemical and molecular study of one caseHistological and molecular features of testicular FRMS. a: Peripheral FRMS subalbuginea intratesticular well-defined nodular tumor (10×), infiltrating the surrounding testicular parenchyma (insert) (20×). b: Fascicles of spindle-shaped cells with small oval or elongated nuclei, vesicular chromatin and pale cytoplasm accompanied by rhabdomyoblastic differentiation (40×). c and d: Immunohistochemical staining was positive for MyoD1 and Myogenin. E: FISH hybridization negative FOXO1A: 13q14 translocation, in the elbow sclerosing rhabdomyosarcoma. f: FISH hybridization did not show FOXO1A: 13q14 translocation, in the FRMS.Back to article page
