Case #247 – March, 2009

A patient, originally from Ethiopia but living in the United States for the past five years, presented to her primary care provider with complaints of abdominal pain. A computed tomography (CT) scan was performed, and cysts were observed in the liver. Serologic testing for Hepatitis B Virus, amebiasis, and echinococcosis were all negative. An aspirate from one of the cysts was drawn, and sent to a pathology laboratory for work-up. Slides made from the specimen were eventually forwarded to the CDC-DPDx for diagnostic assistance. The following images show was what observed on a Papanicolaou-stained (PAP) slide of the specimen. Figures A, B, C and E were taken at 500x magnification; Figures D and F were taken at 1000x magnification. What is your diagnosis? Based on what criteria? What other testing, if any, would you recommend?
