Typical Signalment

• No sex, age or breed predilection
• Pure breed cats seem to develop disease of greater severity. These include:
  • Siamese
  • Himalayan
  • Burmese
  • Abyssinian
  • Persian
• Median age of those affected is 7 years (range 4 months - 17 years)

Description

Feline lymphoplasmacytic gingivitis stomatitis Complex is a poorly understood condition. It presents as erythematous, ulcerative lesios of the gingiva, buccal mucosa, lips, palatoglossal folds and the lateral pharyngeal walls. No clear aetiology has yet been discovered but many different causes of the condition have been proposed:

• Hypersensitivity to oral antigens
• Bacteria
  • Porphyromonas
  • Haemobartonella henselae
• Viruses
  • Feline calicivirus (FCV)
  • Feline herpesvirus (FHV)
  • FIV
  • FeLV
  • Feline coronavirus (FCoV)

Diagnosis

Clinical Signs

• Halitosis
• Dysphagia
• Ptyalism
• Weight loss
• Cachexia
• Bilateral erythematous, ulcerative and/or proliferative lesions of the gingiva
• Submandibular lymphadenopathy
• Variable amounts of plaque and calculus accumulation
• Missing teeth
• Loose teeth

Laboratory Tests

• Virus testing for FIV, FeLV
• Oral Swab for FCV
• Routine haematology and biochemistry to screed for underlying disease.

Diagnostic Imaging

Full mouth radiography should be carried out to assess the teeth, alveolar bone and also to identify any broken roots.

Biopsy

Biopsies should be taken to rule out any malignant neoplasms (ie squamous cell carcinoma) or other pathology ( ie eosinophilic granuloma)
