Answer to Case 491

Answer: Visceral leishmaniasis due to Leishmania species (Leishmania donovani complex or L. tropica). As noted by Brady Page, Anon, Florida Fan, William Sears, and Daniel Skipper, the diagnosis can be easily secured by identifying the amastigotes within mononuclear phagocytes. Each amastigote has a small eccentric nucleus and rod-shaped kinetoplast, giving the so-called "dot-dash" pattern (thank you @JClinMicro)
 And thank you to our poet, Blaine, who gave us the following:
Sheesh! This guy has Leish! 
Maybe from sandflies at the beach? 
PCR should be within reach, 
in case there is a call for Pentostam to release!
