Plain-English summary
A 5-year-old male telescope goldfish developed a bulging left eye, which led to surgery to remove the eye. After the surgery, the fish seemed to recover, but sadly, it declined in health about seven weeks later and had to be euthanized. A postmortem examination revealed that the fish had a tumor in the right eye as well, which had spread to the brain. This case is notable as it is the first documented instance of this type of tumor occurring in a fish.

Abstract
Abstract A 5-year-old male telescope goldfish (Carassius auratus) developed buphthalmia of the left eye. An enucleation was performed and a diagnosis of a neuroectodermal tumor was made on histological examination. Although the fish initially recovered, it was killed 49 days postsurgery due to a severe decline in its condition. On histological evaluation of postmortem tissue samples, it was determined that the fish also had a neuroectodermal tumor of the right eye with local invasion of the brain. On immunohistochemistry, the neoplastic cells were positive for S-100. To the authors' knowledge, this is the first published case of naturally occurring bilateral intraocular neuroectodermal tumors in a fish.
