A case of splenic granulomata in a male Chinese in Thailand is described. The lesion is believed to be caused by microfilariae of Wucheria bancrofti. It is assumed that the granulomatous process occurred as the microfilariae migrated out of the vascular channels and were destroyed in the spleen. The low incidence of the observed lesion is probably due to the reversibility of the process.
