Introduction
Rhabdomyosarcoma (RMS) is a rare malignant tumor of soft tissue, most commonly detected in children and young adults. It makes up about 3-4% of childhood cancer (Kim JR, 2017 Aug; Panda et al., 2017 May). RMS can arise anywhere in the body where there are muscles; in the extremities, head and neck, and the genitourinary tract (Mandeville, 2019 Jul). Imaging is an important diagnostic procedure, whereas; computerized tomography (CT) scans of primary sites with contrast or magnetic resonance imaging (MRI) are considered one of the most reliable diagnostic investigations (Panda et al., 2017 May). The differential diagnosis (DDx) of pediatric RMS includes Lipomas, Liposarcoma, Lymphadenopathy, Lymphoproliferative disorders, Neurofibromatosis type I, Osteosarcoma, Wilms tumor, and Ewing’s sarcoma (Matondang et al., 2020 Apr). The Prognosis for RMS has become more promising because of multi-modal therapy including surgery, chemotherapy, and radiotherapy (Panda et al., 2017 May). Herein, we report a non-metastatic stage 3 bladder RMS in a two-year-old male.
