@entity157 ( @entity157 ) is an @entity99 that even occurs in noncirrhotic liver of males (any age) or females >=  50 years old, or associates focal atypical features. In this article, 2 unusual cases diagnosed in elderly cirrhotic @entity1 , unrelated to @entity230 , are presented. The first case was incidentally diagnosed in an 83-year-old female. During laparoscopic surgery for cholecystectomy, hemoperitoneum was installed and laparotomy was necessary to remove a 70-mm nodular encapsulated @entity99 that was microscopically composed by hepatocyte-like cells with clear cytoplasm, arranged in 1- to 2-cell-thick plates and intermingled with areas of @entity9429 , negative for @entity160 ( @entity160 ), @entity876 , and @entity5822 , with low Ki67 index and intact reticulin framework. The second case was incidentally diagnosed at ultrasound examination in a 66-year-old male. The surgical specimen was a 50-mm solid multinodular @entity5 that microscopically consisted of 3-cell-thick plates of hepatocyte-like cells with acinar, pseudoglandular, and trabecular architecture, intermingled with peliotic areas, without nuclear atypia and disintegrated reticulin framework. Both of the cases occurred in cirrhotic liver. The @entity5 cells were marked by @entity1325 , displayed a Ki67 index < 5% and were negative for @entity160 , @entity876 , and @entity5822 . No recurrences or any @entity74 occurred 6 months after surgery. In cirrhotic liver, @entity652 with @entity9429 that do not satisfy all the diagnosis criteria synthesized in the article should be considered AHNs and differential diagnosis includes @entity157 but also @entity4383 , regenerative nodules, and @entity9384 . This histological entity is not yet included in the WHO Classification list.
