Nodular conjunctivitis as a novel ocular manifestation of canine sterile granuloma/pyogranuloma syndrome

This case represents the first histopathologically confirmed conjunctival manifestation of SGPS. Its conjunctival origin and mixed lymphocytic-histiocytic profile expand the recognized spectrum of SGPS and support including SGPS in the differential diagnosis for well-circumscribed conjunctival nodules. Surgical excision may be required when such lesions do not regress or cause mechanical dysfunction.
