Plain-English summary
A 5-year-old male American Staffordshire Terrier was brought in because he had a mass in his right eye, which was not seeing well and had signs of retinal hemorrhage and detachment. The veterinarian recommended further imaging to understand the mass better, but the owner chose not to proceed with that. Instead, the dog underwent surgery to remove the eye (enucleation). The examination of the eye tissue revealed a type of inflammatory disease that had caused significant damage, leading to the decision to remove the eye. Unfortunately, the dog lost vision in that eye, but the surgery was necessary to address the serious condition.

Abstract
Nodular granulomatous episcleritis (NGE) typically presents as an elevated mass or elevated masses at the limbus and often infiltrates the cornea (episclerokeratitis). In the current report, a granulomatous lesion was observed subretinally in the right eye (OD) of a 5-year-old male castrated American Staffordshire Terrier dog. There was concurrent retinal hemorrhage and detachment OD; the right eye was not visual. Due to poor prognosis for vision and potential for a neoplastic etiology of the mass, staging with higher imaging was recommended but declined by the owner. Therefore, an enucleation was performed. Histopathology of the globe identified a subretinal mass, marked histiocytic and lesser lymphoplasmacytic choroiditis, posterior episcleritis, and optic neuritis with retinal detachment. The subretinal mass was composed of densely packed, large, spindle histiocytes mixed with occasional lymphocytes, plasma cells, and only rare neutrophils. Regions of the mass showed lymphocytes aggregate to form nodules. This histological presentation was a type of proliferative histiocytic disease with similarities to nodular granulomatous episcleritis or granulomatous/necrotizing scleritis. This is a novel presentation of NGE-like progression to subretinal scleral, choroidal, and retinal involvement and provides a new differential possibility for posterior segment masses observed on fundic examination.
