A 47-year-old woman presented a worm-like object to her doctor that she claims was found in the toilet following urination. The object, which measured seven millimeters in length, was preserved in formalin and sent to the local state health laboratory, which in turn sent the specimen to DPDx for diagnostic assistance. Figure A shows the entire object. Figures B and C show the anterior and posterior ends of the object, respectively. What is your diagnosis? Based on what criteria?
