Malakoplakia of the appendix is an unusual condition that has been reported
to occur in association with tumors, infections, and immunocompromised sta
tes. We describe a case of appendicular malakoplakia associated with eggs o
f Taenia species. The diagnosis was made on histopathologic examination of
surgically resected tissue from an appendicular mass. To the best of our kn
owledge, this is the first time that helminths have been documented to be a
ssociated with malakoplakia. We also discuss the implications of helminthic
infestation in the pathogenesis of the lesion.
