[Diffuse cutaneous leishmaniasis. Anatomo-pathologic aspects].

We present a study of 21 biopsies from three patients with diffuse cutaneous leishmaniasis with periods of observation of up to 9 years. The biopsies were taken before, during, and after specific treatment. We observed that a lymphocytic infiltrate may be present in the lesions and that the intensity of the infiltrate is variable from lesion o lesion, even among lesions biopsied at the same time. Tuberculoid granulomatous reactions were not found in the patients following treatment. We conclude that the histologic features of importance in the classification of cutaneous leishmaniasis are: the tuberculoid granulomatous reaction and the intensity of parasitism.

Pneumonitis in congenital Chagas' disease. A study of ten cases.

Ten cases of pneumonitis in congenital Chagas' disease are described. Amastigotes were found in the lungs in seven cases, and in two of these cases parasitized cells were seen in the alveolar lumen. In five cases parasites were found both in the lungs and in the amniotic epithelium of the extraplacental membranes and umbilical cord. The authors conclude that infection of the amniotic epithelium originated in the lungs and was carried by the amniotic fluid, and emphasize the epidemiological importance of infection of the amniotic fluid as a probable means of transmission of Chagas' disease among professionals working in the area of obstetrics.
