Feline Dermatoses (Gram) Flashcards
Miliary dermatitis syndrome (Scabby cat disease)
- Not a specific diagnosis, it’s a symptom/rxn pattern
- “Seedy”
Miliary dermatitis syndrome clinical signs
Papular seedy eruption, frequently on dorsal neck and back
Miliary dermatitis syndrome etiologies
- Fleas, notoedres, otodectes
- Flea allergy, atopy, food allergy
- Dermatophyte, bacteria
Miliary dermatitis syndrome diagnosis
- Clinical signs
- Look for underlying cause
- Hx suggestive of allergies
- Skin scrapings
- Fungal culture
- Response to flea control
Miliary dermatitis syndrome treatment
- Long term (define underlying cause)
- Short term
- Depomedrol
- Prednisolone
- Other immunomodulating agents
Eosinophilic Granuloma Complex manifestations
- Indolent ulcer
- Eosinophilic plaque
- Collagenolytic granuloma
Indolent ulcer (eosinophilic granuloma complex)
- Inflammatory ulcer usually located on upper lip
- Unilateral or bilateral
- Potential concurrent nodular pharyngeal granuloma
- Associated w/ underlying allergy
- Rarely can progress to squamous cell carcinoma
(Indolent in this case means painless or slow to change)
Indolent ulcer (eosinophilic granuloma complex) diagnosis
- Clinical signs & hx
- Biopsy
- R/O other conditions
- Check to see if it’s become neoplastic
- +/- eosinophils
Indolent ulcer (eosinophilic granuloma complex) treatment
-
Treat underlying disease
- Flea control
- Abx
- Glucocorticoids
- +/- cyclosporine
- Chlorambucil (resistant ulcers)
Eosinophilic plaque (eosinophilic granuloma complex) clinical features
- Well circumscribed red/yellow edematous plaque
- Intensely pruritic
- Groin or medial thighs
- Associated w/ allergic dz (esp. flea allergy)
Eosinophilic plaque (eosinophilic granuloma complex) diagnosis
- Clinical signs
- Histopathylogy
- spongiotic dermatitis w/ severe eosinophilic infiltrate
Eosinophilic plaque (eosinophilic granuloma complex) treatment
- Control underlying allergy
- ASIT
- Food trial
- Flea control
- Glucocorticoids or cyclosporine
Collagenolytic granuloma (eosinophilic granuloma complex) forms
- Linear granuloma (linear, raised, on caudal aspect of hind legs, variable pruritis)
- Nodular pharyngeal granuloma (firm pink/yellow lesions, usually assoc. w/ indolent ulcer)
- Chin form (“fat chin”)
Collagenolytic granuloma (eosinophilic granuloma complex) diagnosis
- Hx
- Clinical signs
- Histopathology
Collagenolytic granuloma (eosinophilic granuloma complex) treatment
- Glucocorticoids
- Look for underlying allergy
