RESUMO
A 51-year-old man presented with a three-month history of a red and painful right eye. A corneal ulcer was diagnosed, and laboratory workup failed to disclose an etiologic factor. A white tumor, with an irregular and calcified surface, found in the superior tarsal conjunctiva, was considered to be the cause of the corneal ulcer. The tumor proved to be a pilomatrixoma that presumably developed from a congenitally ectopic hair follicle.

Data concerning the molluscicidal activity of 159 extracts from 84 Brazilian plants on Biomphalaria glabrata, the most important intermediate host of Schistosoma mansoni in Brazil, are presented. Seventy eight extracts (49,0%) showed activity against snails or eggs, but only twenty nine (18.2%) were active on both, snails and eggs. Extracts of two species (Mikania hirsutissima and Qualea multiflora) have shown to be lethals to adult snails at 10 ppm concentration.
