Here is the latest tropical medicine vignette from the McGill-CanTropMed listserv. Each month they send out a new picture and brief information on a tropical medicine disease. The answer can be found by clicking a link at the bottom of the page. Thanks to the McGill University Ceter for Tropical Diseases for this service and J Dick MacLean MD, FRCPC, MRCP(UK) DCMT(Lond) who is the Director/Professor.
Here is this month’s link: Tropical Med Vignette. Also, here is the link for the archives of previous questions.
Good luck!
