Splenogonadal fusion (SGF) is a very rarely seen congenital anomaly localized usually in the left testis and mimics a testicular tumor. There are two subtypes of SGF, as continuous and discontinuous SGF. Continuous SGF can usually be detected in childhood. The less common discontinious SGF may not be detected until adulthood, and may be mistaken for testicular tumor and cause unnecessary orchiectomies. In this case report, we aimed to present a patient who underwent orchiectomy due to a left testicular mass associated with hydrocele and was found to have discontinuous SGF in his histopathological evaluation.
