title: [Pneumoblastoma. Report of a case. Immunohistochemistry and discussion of histogenesis].
abstract: A case of pulmonary blastoma in a 50-year old man is reported. The initial diagnosis was one of pulmonary hydatid cyst, but at surgery a solid tumour of the left upper lobe was discovered. The histological study showed the characteristic features of pulmonary blastoma with its two components: epithelial and mesenchymatous. Immunohistochemistry yielded a double cellular response to keratin and vimentin--a finding which supports the hypothesis of a tumour arisen from a multipotent cell.
