This case report discusses a 24-year-old male with undescended testicles (UDTs) who was diagnosed with locally invasive testicular seminoma.
The patient, initially suspected of having an inguinal hernia, was found to have an atrophic left testis in the inguinal canal. Despite normal tumour markers and ultrasound findings, a subsequent examination and histopathology after orchidectomy revealed invasive seminoma.
This case underscores the importance of adhering to guidelines for managing UDTs in post-pubertal males to minimise cancer risk, advocating for early orchidectomy over surveillance due to the unreliability of ultrasound in detecting malignancy in cryptorchid testes.
