Objective: To present the clinical signs and treatment methods for atypical tumor‐like meibomitis in two dogs. Animals Studied: A 4‐year‐old castrated‐male Coton de Tulear (Case 1) and a 6‐year‐old spayed‐female Maltese dog (Case 2). Procedure: Full ophthalmic examination revealed a well‐circumscribed, firm, and raised solitary mass on the upper eyelid of the left (Case 1) and right eye (Case 2). Case 1 showed a recurrent mass with a diameter of 2–3 mm, which was excised by the referring veterinarian. The possibility of meibomian gland involvement was suggested histopathologically. Case 2 had a history of blepharitis treated with systemic corticosteroids 4 years ago. Results: Topical and systemic antibiotics and anti‐inflammatory drugs were administered to reduce inflammation and prevent secondary infections. In Case 1, the mass appeared static at the beginning of medication; however, after stopping antibiotics while tapering steroids, the mass increased in size and was associated with suppurative discharge. In Case 2, the mass continued to grow despite treatment, showing a similar infection pattern. Cytological examination revealed neutrophilic inflammation with cocci infection, and bacterial culture confirmed the presence of Staphylococcus pseudintermedius in both cases. When steroid administration was stopped and antibiotic administration was initiated according to the results of the antibiotic susceptibility test, the mass rapidly decreased in size and completely disappeared. There was no recurrence on follow‐up. Conclusions: A unilateral antibiotic‐responsive tumor‐like solitary mass on the upper eyelid resolved without surgical treatment. Medical treatment must be considered when treating atypical eyelid masses, and the use of appropriate antibiotics through antibiotic susceptibility testing is important. [ABSTRACT FROM AUTHOR]
