Plain-English summary
A 7-year-old neutered male dog developed a lump in the scrotum after being castrated, which turned out to be a Sertoli cell tumor, a rare type of testicular tumor. This dog, along with five neutered male cats, showed signs of secondary sexual characteristics due to the tumor. After the tumors were surgically removed, all the pets returned to normal without any complications or signs of cancer spreading. The exact cause of these tumors is still being studied, but it may relate to leftover testicular tissue from the neutering process.

Abstract
Primary neoplasms derived from testicular tissue and in an extratesticular location are extremely rare. Clinical and surgical information was collected and verified from 15 different submitting practices for 12 dogs and 5 cats that spontaneously developed neoplasms of testicular origin after castration. Eleven dogs had Sertoli cell tumors in an extratesticular location. One dog and all 5 cats had an extratesticular interstitial cell tumor. Six animals (1 dog, 5 cats) had developed secondary sexual characteristics that reversed after removal of the tumor. All had a palpable mass in the scrotum or at the site of the original prescrotal incision. No animals died of neoplasia-related disease and no metastases were identified. Several possibilities, including the presence of embryological ectopic tissue or the presence of testicular tissue transplanted during castration, are considered as causal.
