Contemporary chemotherapy regimens have led to improved survival and decreased incidence of testicular relapse for pediatric patients with acute lymphoblastic leukemia (ALL). Local therapies to the testes, such as radiotherapy and orchiectomy, are often not necessary given that high-dose chemotherapy agents can overcome the relative blood-testis barrier. However, urologists should be aware of clinical scenarios involving ALL which still warrant testicular biopsy to guide management. Here, we present a case of a 12-year-old boy with high-risk pre-B cell ALL presenting with a testicular relapse and a clinical presentation overlapping with non-infectious epididymo-orchitis.
