Abstract:
Résumé- Cet article décrit le cas d'une chienne Colley de 12 ans ovariohystérectomisée qui présentait un prurit sévère. Les racalges cutanés ont permis de mettre en évidence deux on trois sarcoptes et des œufs par champ à faible grossissement. Le chien avait des symptômes compatibles avec une hypothyroïdie qui a été objectivée ensuite par des tests hormonaux dynamiques. La similarité de ce cas avec la gale norvégienne de l'homme est discutée. L'hypothèse d'une prédisposition des chiens hypothyroïdiens à développer ce type de gale est soulevée. [Jackson, H. A. A case of concurrent Sarcoptes scabiei infestation and hypothyroidism in a dog (A propos d'un cas de gale àSarcoptes scabiei associée à une hypothyroïdie). Resumen- En este articulo se describe un caso de un perro hembra (castrada) de raza Collie de pelo duro que presentaba un cuadro de intenso prurito. Tras un raspado cutáneo se detectaron dos o tres ácaros y huevos del género Sarcoptes mediante observación microscópica a pequeño aumento. El perro presentaba un cuadro clinico compatible con hipotiroidismo, que fue confirmado posteriormente con una prueba de estimulación. Se discute la semejanza de esta presentación con la sarna sercóptica noruega en la especie humana y se postula que la posibilidad que un estado hipotiroideo pueda predisponer a desarrollar sarna sarcóptica.

Abstract- This report describes a 12-year-old ovariohysterectomised female rough collie which was presented with severe pruritus. On scraping the skin two or three sarcoptic mites and eggs per low power field could be seen under microscopic examination. The dog had clinical features compatible with hypothyroidism which was subsequently confirmed with provocative testing. The similarity of this presentation with that of Norwegian scabies in man is discussed and it is postulated that a hypothyroid state might predispose to the development of severe sarcoptic mite infestation.
