BACKGROUND:

Porcine ulcerative dermatitis syndrome (PUDS) is a rare disease of breeding sows with an unknown pathogenesis.

OBJECTIVE:

To describe the evolution of clinical and histopathological lesions over the course of the disease and to elucidate the pathogenesis.

ANIMAL:

A 24-month-old, pluriparous, large white sow presented during gestation with ulcerations around the teats compatible with PUDS.

METHODS AND RESULTS:

Clinical 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 IMPORTANCE:

The 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.
