Aural cholesterol granuloma in a dog.
A five-year-old female Irish setter was referred for surgery for a left-sided aural mass. The dog was generally well, but had signs of left-sided otalgia for one week. Biopsy identified the lesion as a cholesterol granuloma. The mass was removed three weeks later by a total canal ablation/lateral bulla osteotomy. The dog recovered from surgery without any complications. Ten months later, there was no evidence of recurrence. The purpose of this paper is to report the clinical and histopathological findings of this unusual form of granuloma which has not previously been reported in the canine ear.

Cerebral healing after craniotomy to evacuate a Coenurus cerebralis cyst.
An 11-month-old ewe developed neurological signs caused by a space-occupying lesion in the left cerebral hemisphere. Successful surgical evacuation of a Coenurus cerebralis cyst was carried out, the neurological signs regressed and the ewe produced twins in the following breeding season. Sixteen months after the surgical treatment the ewe was found dead and necropsy revealed a vegetative endocarditis. In the brain, at the site of cyst evacuation, there was a collapsed subcortical cavity lined by siderotic fibrovascular tissue and surrounded by a modest glial reaction. These observations confirm that the clinical signs of cerebral coenuriasis are related to the space-occupying effect of the parasitic cyst and indicate that partial replacement by gliomesodermal tissue plays a part in healing of the collapsed cyst.

Endometrial carcinoma in a young dog.
A 2-years-old nulliparous cross-bred bitch had persistent vulval discharge following treatments that included a combined ethinyloestradiol/methyltestosterone preparation and megoestrol acetate. The uterus, removed at ovarohysterectomy, contained a large polypoid intraluminal mass with the histological features of endometrial carcinoma. The bitch has remained well for thirty-one months after surgery. The possibility is considered that the lesion is drug-related but no firm conclusion can be drawn about the precise nature and pathogenesis of this unusual lesion.
