Figure 5, A through D, shows a needle biopsy of a mediastinal lymph node from a 58-year-old man with a recent diagnosis of prostate adenocarcinoma (Gleason pattern 4, "hypernephroid"), a nephrectomy 5 years prior for "sarcomatoid" renal cell carcinoma, and a remote history of melanoma who presented with mediastinal and lung masses.
The TURP revealed that 30% of the specimen contained Gleason 4+5=9/10 prostatic adenocarcinoma, with clear cell or hypernephroid morphology.
