Case of the Week 625

 This week ' s case was generously donated by Dr. Marijo Roiko, Dr. Shifteh Vahidi, and Ms. Marnie Larsen. Marnie noticed the unusual structure shown in the image below in a urine cytology specimen from an elderly male with a history of hematuria. The structure in the image was observed on PAP stain and was a solitary finding; it measures 125 x 75 µm. What is this cool-looking object?
