| Abstract: | The authors report clinical and histopathologic changes in six patients with symptomatic loiasis. One patient had cutaneous swellings, three patients presented with hydrocele, one patient developed bowel obstruction, and one had generalized fatal loiasis. The first five patients had localized lesions provoked by adult worms; all were surgically removed. The sixth patient died of disseminated loiasis that included a severe loal encephalitis. The authors discuss the mechanism of "Calabar" swellings, the reaction to adult Loa loa worms and loal encephalitis. |
