Protoscoleces of Echinococcus?

A really beautiful case of hydatid cyst. We can clearly see the protoscoleces and the hexacanth row of hooklets.

Dr. Pritt's comment on the use of Carmine stain cannot be any better. Carmine stain along with Hematoxylin Eosin stain give us excellent teaching slides to demonstrate the anatomy of the worms. These stains are quite lengthy to perform and the timing of each step depends very much on how thick the organism is, and in many cases have to be monitored with microscopic examination to produce a usable teaching slide.
Unfortunately with the productivity oriented work pace, these sciences fall gradually into obsolescence, or in better wording "lost art".

Is this case by chance from a middle aged man in the Midwest? Very interesting!
