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 A–D 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?
