Abstract:
Rhabdomyosarcoma (RMS) of the prostate is a rare tumor in infants. RMS frequently arises in genitourinary tract (~20% of cases), with the embrional subtype being the most common. 1,2 The presenting symptoms are usually not specific, often leading to an extensive diagnostic work-up before identifying RMS. 3,4 Furthermore, there are no biomarkers specific to RMS. We present the case of a 4-month-old boy with postrenal acute kidney injury (AKI). Abdominal ultrasound and magnetic resonance imaging (MRI), followed by ultrasound-guided fine-needle aspiration biopsy and citopathological examination, established the diagnosis of prostatic RMS, which was later staged with 18 F-FDG PET/CT. 5.
