Cutaneous skin lesions in swine

The lesions observed in this case correspond to a swine juvenile psoriasiform pustular dermatitis also known as Pityriasis rosea, due to the similarity of the lesions with the human disease counterpart.

This disease is of unknown cause, it affects only the skin and has no pathological significance, causing merely organoleptic alteration of the carcass.

The differential diagnosis of these lesions can be: swinepox, dermatosis vegetans and ringworm.

Erythematous ring shaped lesions, distributed on the animal's back.

Detail of lesions in the lateral aspect of the carcass. Some of the papules converge between them.

The lesion also extends to the medial aspect of the hindlimbs
