| Abstract: | A 3-year-old sexually intact female Bernese Mountain Dog was referred for treatment of a descemetocele of the left eye. Physical examination revealed bilateral exophthalmos and scleral thickening, multiple cutaneous nodules, and mandibular paralysis in addition to ulcerative keratitis associated with a Pseudomonas infection. One year prior to examination, a biopsy specimen of the episcleral tissue from the right eye had been interpreted as nodular granulomatous episclerokeratitis (fibrous histiocytoma). Immunosuppressive treatment prior to referral had not resulted in remission of the ocular lesions. When we examined the biopsy specimen, we interpreted the lesions to represent episcleral involvement of systemic histiocytosis. Because of the poor prognosis, the dog was euthanatized. |
