| Summary, etc. | Une vache Prim’Holstein de 9 ans, présentant des lésions ulcéreuses cutanéo-muqueuses, a été autopsiée. L’examen nécropsique a révélé une hépatite nécrosante multifocale extensive, une cholangite fibrineuse sévère et une cholécystite fibrineuse diffuse. Ces lésions hépatobiliaires sont compatibles avec une photosensibilisation hépatogène (type III), consécutive à une incapacité d’élimination de la phylloérythrine. Les lésions cutanées érythémateuses et ulcéreuses sévères, localisées aux jonctions cutanéo-muqueuses, en sont les conséquences visibles. L’analyse histologique a confirmé la nécrobacillose hépatique à Fusobacterium necrophorum, malgré l’absence de mise en évidence bactériologique. La liste du diagnostic différentiel est également discutée. Ce cas illustre l’importance de considérer la photosensibilisation hépatogène comme conséquence secondaire d’atteintes hépatiques infectieuses. Le retrait du pâturage, la photoprotection et le traitement des lésions cutanées sont essentiels pour limiter les complications. |

| Summary, etc. | A 9-year-old Prim’Holstein cow with ulcerated mucocutaneous lesions was necropsied. Necropsy revealed extensive multifocal necrotising hepatitis, severe fibrinous cholangitis and diffuse fibrinous cholecystitis. These hepato-biliary lesions are compatible with hepatogenic photosensitisation (type III), due to an inability to eliminate phylloerythrin. Severe erythematous and ulcerative skin lesions, localised at the mucocutaneous junctions, are the visible consequences. Histological analysis confirmed necrobacillosis of the liver due to Fusobacterium necrophorum, despite the absence of bacteriological evidence. A differential diagnosis was discussed. This case illustrates the importance of considering hepatogenic photosensitisation as a secondary consequence of infectious liver disease. Withdrawal from grazing, photoprotection and treatment of skin lesions are essential to limit complications. |
