Case #444 – May, 2017

A 37-year-old male immigrant from the Middle East sought medical attention for pain in the upper right abdominal quadrant. Ultrasonography revealed a single compartment hepatic cyst approximately 7 cm in diameter and during the imaging, a fine biopsy needle was used to obtain an aspirate specimen. The specimen was sent to the CDC DPDx Team for examination.  Figures AD show what was observed at 200x magnification; Figures A and B are of the same microscopic field but different focal planes.  What is your diagnosis?  Based on what criteria?  What, if any, other tests would you recommend?
