Hepatocellular adenoma subtypes—Which is it?
July 2017—Kisha Mitchell Richards, MBBS, a pathologist at Greenwich Hospital, Yale New Haven Health, Greenwich, Conn., recalls that when she was a resident, adenoma was just adenoma. “Nowadays it’s not quite where breast is, where it’s a two-page report, but there are now subtypes of hepatocellular adenomas,” she said in a CAP16 presentation on liver neoplasms. The subtypes are the HNF1 alpha or TCF1 inactivated adenoma, inflammatory adenoma, beta-catenin mutated adenoma, and the unclassified adenoma, which she notes is basically adenoma NOS (not otherwise specified).
