Overview

Retrospective evaluation describes oral lymphoma behavior in canines, indicating the need for improved diagnostics.

Key Points

  • This study aims to describe the clinical presentation and outcomes of canine oral lymphoma.
  • Retrospective review of 75 canine cases diagnosed with oral lymphoma from 2019 to 2022.
  • Evaluation of histologic categorization, lesion characteristics, and survival data.
  • Analysis of epitheliotropic and nonepitheliotropic forms of oral lymphoma.
  • 73 cases (97.3%) were diagnosed as epitheliotropic T-cell lymphoma (ETCL).
  • 65.3% of ETCL lesions were located at the mucocutaneous junction, predominantly on the mandibular labial frenulum.
  • 46.7% of lesions were solitary, and 62.8% were ulcerated, with patient survival not significantly associated with lesion number.
