RESUMO
A statistical review of the archives of the Laboratory of Pathologic Anatomy of Maputo Central Hospital is made with the view to determine the frequency of occurrence of rhinosporidiosis in biopsies in the years 1944-86. Diagnosis was made based on the specific microscopic picture shown by the lesions induced by Rhinosporidium seeberi. Of 91,000 reports only 33 cases of the disease were found, which accounts for 0.036% of the total biopsies made in the department. Tissular examinations showed that lesions always appear as polypoid masses lined with hyperplastic epithelium, with an intense inflammatory reaction involving the sporangia, which in slides appear as double-membrane spheres with the occasional rupture-freed spores. It was found that in the series studied the disease appeared most frequently in the period ranging from 10 to 19 years of age, with no sex prevalence. General statistics indicate that the greatest damage was found in bulbar conjunctiva and that location in nostrils was the most frequently found in the age group with the youngest people.

The purpose of this paper is to carry out an analysis of the term leukoplakia since its introduction in 1877 and to expose the most accepted concepts and present classification within specialists. For this purpose attention will be paid to definitions established in the international seminary developed in Malmö City, Sweden, in June 1983. A group of observations on present status of research and diagnostic methods and its limitations to pre-establish when a lesion of this type is going to evolve toward malignancy, is included. An important part of this paper is devoted to the linguistic analysis of leukoplakia and leukoplasia expressions. An extensive argumentation demonstrating the systematic impropriety in the Spanish Language of translating the English term "leukoplakia as leukoplasia, is presented. There is in Spanish the accurate translation, given by the expression leukoplakia, which is not only the adequate one for the exactness of its translation but also the one more conceptually adjusted to contemporary definition universally accepted, that is to say, a white plaque. Finally, a comment on importance of incorporates to our language the exact translation of scientific words, not only to fit it to present science, but also to a better fulfillment of its function in allowing the communication within Latin American researches themselves and with the world scientific community, is exposed.
