title: Pulmonary trophoblastic deportation. Cytologic aspects.
abstract: In the present paper the human pulmonary trophoblastic deportation was studied in 180 sputum specimens from 90 pregnant, parturient and puerperal patients. The syncytial trophoblastic cells were searched in the sputum with the Papanicolaou and Shorr techniques. The morphology of the isolated syncytial trophoblastic cells was studied in placental imprints and compared with isolated megakaryocytes in bone marrow smears. The data in the literature and our own results suggest that the absence of syncytial trophoblastic cells in the sputum from pregnant, parturient and puerperal patients may be due to the following factors: (a) all the patients were normal; (b) the syncytial trophoblastic cells degenerate in the pulmonary capillaries and therefore do not reach the alveoli; (c) the specimens were collected without any special technique. This investigation must be carried out in abnormal conditions of "placental commotion" such as eclampsia, caesarian section, uterine manipulation, etc.
