ABSTRACT
An 11-year-old neutered male large crossbreed dog was presented for investigation because of a 10-day history of progressive lethargy, hyporexia, and pyrexia. Physical and dermatological examinations were unremarkable. Blood biochemical analysis identified a marked total and ionized hypercalcemia and increased C-reactive protein concentration. Bicavitary computed tomography screening for causes of the dog's clinical and biochemical abnormalities identified a diffuse panniculitis. Histopathological examination of full-thickness skin biopsies was consistent with pyogranulomatous inflammation. Extensive histochemical staining revealed no infectious etiology. Complete clinical and biochemical remissions were observed after starting immunosuppressive, followed by tapering, doses of prednisolone, supporting an immune-mediated etiology. Key clinical message Sterile, immune-mediated pyogranulomatous inflammation should remain a differential diagnosis for hypercalcemia in dogs. Significant dermatological disease may occur without visible abnormalities.
Panniculite pyogranulomateuse à médiation immunitaire avec hypercalcémie chez un chienUn grand chien croisé mâle castré de 11 ans a été présenté pour examen en raison d'antécédents de léthargie progressive, d'hyporexie et de pyrexie depuis 10 jours. Les examens physiques et dermatologiques étaient sans particularité. L'analyse biochimique du sang présentait une hypercalcémie totale et ionisée marquée et une concentration accrue de protéine C-réactive. Le dépistage par tomodensitométrie bicavitaire des causes des anomalies cliniques et biochimiques du chien a identifié une panniculite diffuse. L'examen histopathologique des biopsies cutanées de pleine épaisseur était compatible avec une inflammation pyogranulomateuse. Un examen par coloration histochimique extensive n'a révélé aucune étiologie infectieuse. Les rémissions cliniques et biochimiques complètes ont été observées après le début du traitement immunosuppresseur, suivies d'une diminution progressive des doses de prednisolone, confirmant une étiologie à médiation immunitaire.Message clinique cléL'inflammation pyogranulomateuse stérile à médiation immunitaire doit rester un diagnostic différentiel de l'hypercalcémie chez le chien. Une maladie dermatologique importante peut survenir sans anomalies visibles.(Traduit par Dr Serge Messier).
