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.
