Clinical and pathological classification of canine intraocular lymphoma.

The objectives of this retrospective study of 100 dogs with intraocular lymphoma were to describe the histomorphologic and immunohistochemical features of canine intraocular lymphoma, determine the proportion of cases with presumed solitary ocular lymphoma (PSOL) compared to multicentric disease, and assess the clinical outcomes of these patients. Selected cases from Penn Vet Diagnostic Laboratory and Comparative Ocular Pathology Lab of Wisconsin (2004-2015) were evaluated and subtyped using the WHO classification system. Peripheral T-cell lymphoma and diffuse large B-cell lymphoma were the two most common subtypes.

Canine ocular protothecosis: A review of 14 cases.

Purpose: To examine a series of 14 cases of canine ocular protothecosis from archived cases from the Comparative Ocular Pathology Laboratory of Wisconsin (COPLOW), and compare gross and histologic findings.

Methods: Archival records from COPLOW were searched for canine cases of ocular protothecosis. Fourteen cases that contained matching criteria were identified, and gross and histologic findings, and clinical records for each case were tabulated, examined, and compared (2001-2013).
