[Clinical Picture] Rare primary prostate cancer presenting with testicular and hip pain

A 61-year-old male patient was referred to the urology department of the University College London Hospitals (London, UK) in June, 2022, after experiencing left testicular and hip pain. Prior to the referral, his local general practitioner had prescribed antibiotics for suspected epididymo-orchitis. His symptoms improved and the patient was reassured. 1 month later, his pain relapsed and hip osteoarthritis was suspected. X-ray examinations were unremarkable, but upon further evaluation, a pelvic MRI demonstrated a prostatic tumour with apparent rectal wall invasion (figure, A).
