Case #261 - October, 2009

A Pathology laboratory in Australia received proglottids and eggs of a cestode that were recovered from the stool of a young female patient who had been living in Africa. The only other information given was that the patient had close contact with monkeys. The laboratory had telediagnosis capabilities and sent images to DPDx for confirmation (Figures A and B, taken at 400x magnification). The objects depicted in the images measured 52-61 micrometers in diameter. What is your diagnosis? Based on what criteria?
