December Case of the Month

Clinical History: An 81-year-old woman was admitted to the hospital for influenza. She was a former smoker with 15 pack-years, but otherwise had no significant past medical history. Imaging at that time revealed an incidental 3.1 cm left upper lobe nodule (SUV 4.7) involving the hilum, and she underwent a bronchoscopic biopsy of this mass.

Histologic images and key IHC and special stains are illustrated below.

A fusion panel detected an EWSR1::CREM fusion.
