Multidrug-Resistant Escherichia coli Canaliculitis.

Escherichia coli canaliculitis is an exceptionally rare organism to cause primary canaliculitis. The present case describes unilateral canaliculitis refractory to conventional therapy with a significant history of recurrent culture proven E. coli urinary tract infection. Microbiological analysis revealed E. coli bacilli and histological examination showed goblet cell metaplasia, subepithelial edema with acute and chronic inflammatory infiltrate. The possibility of an endogenous infection or autoinoculation secondary to urinary tract infection cannot be ruled out.
