Focal nodular hyperplasia, a benign tumour of the liver.

Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60-70% of cases.

Focal nodular hyperplasia (FNH) is the second most common tumor of the liver.

Benign neoplasms include hepatocellular adenoma, hepatic hemangioma and focal nodular hyperplasia.

Benign neoplasm of liver include hepatic hemangiomas, hepatic adenomas, and focal nodular hyperplasia (FNH).

Hemangioma Hepatic adenoma Focal nodular hyperplasia Cysts Lipoma Fibroma Leiomyoma None of these tumors are treated like liver cancer.

It is important to distinguish hepatic adenoma from other benign liver tumors, such as hemangiomas and focal nodular hyperplasia, because hepatic adenomas have a small but meaningful risk of progressing into a malignancy.

It is extremely common to find incidental nodules on liver scans, most commonly due to focal nodular hyperplasia (FNH), as these are a hundredfold times more common in HHT compared to the general population.
