Case of the Week 264

In going through our archives the other day, I found this absolutely stunning slide.  I believe it is stained with a modified Trichrome stain, although the purple coloration is very striking.
Click on the images to enlarge - they're even better in large format.

    Spectacular case.

    Many pathologists will miss this on real cases unless we see the scolices which stain!! We generally like flatter lower contrast microscopy and, forgiving poor nomenclatures, have our condensers relatively wide open.

    ZN stain will show that many of the hookelts are acid-fast. :)

    To anonymous - I also leave my condenser wide open for my surgical pathology and cytopathology cases, but I've learned that when looking for hooklets, to always flip your condenser down. It really makes the hooklets 'pop'!
