Don’t quote me, parasitic histology has never been my ice cream. From what the pictures show, the host tissues encapsulates the parasite cyst. The cyst has a thick clear wall with a germinal layer inside. The protoscolices in the second picture has the hooklets. As such, my uneducated guess is hydatid cyst of Echinococcus granulosus. How is it different from the other cyst formation? This one has more than one parasite, each protoscolex will mature into another cyst and propagate within the unfortunate host. This cyst also does not form “en grape” as in the case of E. multilocularis. Finally there is much more for me to learn than what I already know. Florida Fan
The single protoscolex in a single vesicle, together with the muscular location, seems more consistent with a cysticercus. If so, these are probably Taenia solium larvae, but this cannot be affirmed without molecular biology, as few other Taenia species were described to cause cysticercosis in humans (T. martis, T. crassiceps)
i am favoring your diagnosis still as we do not have any details about the patient history ,it stills confined to the most popular diagnosi one cyst of teania solium until proved other wise

I think it's Trichinella spiralis
ReplyDeleteI think it is Taenia solium. Cysticercosis
ReplyDeleteThin-walled cyst with fluid, spiral canal with foldings, suckers, scolex ± hooklets = cysticercus
