BACKGROUNDPorcine ulcerative dermatitis syndrome (PUDS) is a rare disease of breeding sows with an unknown pathogenesis.OBJECTIVETo describe the evolution of clinical and histopathological lesions over the course of the disease and to elucidate the pathogenesis.ANIMALA 24-month-old, pluriparous, large white sow presented during gestation with ulcerations around the teats compatible with PUDS.METHODS AND RESULTSClinical and histopathological lesions were monitored over the course of the disease (i.e. during and after the subsequent pregnancy). A clear gestation-dependent flare of the lesions was observed with partial resolution occurring postpartum. The histological pattern presented as a lymphocytic interface dermatitis.CONCLUSIONS AND CLINICAL IMPORTANCEThe findings in this case report link gestation with the development of clinical signs and histological changes. Multiparity appears to enhance severity and may finally result in a self-perpetuating disease. Therefore, it seems advisable to cull breeding sows after they have developed PUDS.
