ffelis

Introduction

  • Only 6 reported cases of viral papillomas in cats.
  • Lesions were benign in all cases.
    Do not confuse papillomas with feline viral plaques.
  • Middle aged to old cats.
  • Cause: oral papillomas associated with Felis catus papillomavirus type 1.
  • Cause of cutaneous papillomas unknown.
  • Signs: multiple masses on ventral surface of tongue or solitary mass maybe most common around head.
  • Diagnosis: clinical appearance for oral papillomas; however, histopathology of biopsy required for definitive diagnosis.
  • Treatment: probably will resolve spontaneously.
  • Prognosis: limited data suggests excellent prognosis.

Pathogenesis

Pathophysiology

  • Papillomavirus infects basal cells.
  • Infection results in marked epithelial hyperplasia.
  • Thickened epithelium becomes folded resulting in an exophytic lesion.
  • Spontaneous regression occurs when body mounts cell-mediated immune response against infected cells.
  • In contrast to viral plaques Skin: cutaneous viral plaques, there is no evidence that papillomas predispose to neoplasia in cats.
