The diagnostic challenge presented by an amelanotic uveal cyst with an atypical appearance in a 9‐year‐old Yorkshire terrier dog is reported. The dog was presented with a peculiar cystic neoformation adherent to the edge of the pupil of the right eye. The cyst wall was attached to the pupillary margin and it was bean‐shaped, measuring approximately 4.5 × 2.5 mm. It was white in colour with several red striations and a small brown spot in the middle, which conferred on it a peculiar appearance. The cyst could not be transilluminated and partially impaired vision. Apart from that, the ophthalmic exam revealed no other abnormalities and the eye showed no signs of inflammation. Ocular ultrasound revealed the cystic nature of the neoformation. During paracentesis of the anterior chamber, the cyst was deflated and both the cyst wall and fluid were aspirated. The tissue obtained was sent for a histological examination and was considered as corresponding to a uveal cyst. The dog improved from the post‐operative uveitis without any complication and after 24 months of follow‐up showed no recurrences.
