Pathological and immunohistochemical findings in the skin of an Egyptian goose naturally infected with avian pox virus are described in this paper. Cutaneous papules and nodules were observed on the unfeathered parts of the skin. Histopathological examination revealed hyperplasia of the epithelial cells of the stratum spinosum, with presence of eosinophilic intracytoplasmic inclusions. Avipoxvirus was detected in the formalin fixed paraffin embedded tissues of goose skin by immunoperoxidase and immunofluorescence. To our knowledge, this could be the first record of avian pox in geese in Egypt.
