Intestinal obstruction due to Basidiobolus ranarum: an unusual case.

A case of intestinal obstruction caused by extensive soft tissue fungal infection of the perineum due to Basidiobolus ranarum is presented here. There was excellent response to antifungal treatment. A literature search revealed the case report of intestinal obstruction due to intrinsic mucosal involvement by the fungus, but extensive soft tissue involvement of the perineum resulting in extraneous obstruction to the rectum, has not been reported so far.
