This week's case is a Giemsa-stained sputum specimen from a patient with abrupt onset of productive cough and expectoration of "salty-tasting" fluid. Images are shown at 400. and 1000x. Identification?
Protoescoleces of Echinococcus granulosus. In the second image you can see the row of hooklets. In our hospital (south american) this parasite is becoming more and more usual.
This may be a sample of hydatid sand (leakage from hydatid cyst which contains protoscolics and free hooklets from Echinococcus granulosus. Why it is not E. multilocularis? I think because E. multilocularis is usually sterile( no hooklets and protoscolics) and I do not think it can be found in the lung (usually it is in the liver).However, It could be E. vogeli or E. oligathus.

Agree but then how could we differentiate it with E. multilokularis?
ReplyDeleteAgree with Echinococcus identification.

Agree with Echinococcus spp. (Hooklets)

Protoscoleces of Echinococcus spp. (It could E. granulosis or multilocularis rather than vogeli or oligarthus which are very rare in humans)

E.granulosis
ReplyDeleteThe salty taste comes from the content of a ruptured cyst.
E.multilocularis doesn't form cysts
