摘要
We report 2 cases of embryonal rhabdomyosarcoma, a rare malignant tumor, arising from the tunica dartos in the scrotum. Sonography revealed that each tumor had clear boundaries, a complete capsule, abundant blood flow, and an internal hypoechoic signal. Patients with embryonal rhabdomyosarcoma who have suspected lymph node metastases or distant metastatic lesions should undergo computed tomography. Our 2 cases were confirmed by subsequent histopathologic diagnosis and immunohistochemical staining with desmin and myogenin. The 2 patients were treated surgically with radical excisions and chemotherapy but without radiotherapy. To our knowledge, no cases of embryonal rhabdomyosarcoma originating from the scrotal tunica dartos have previously been reported in the medical literature.
