Hepatic adenoma is a benign liver tumor that can degenerate into a malignant form.
Causes of hepatic adenoma are not entirely known. It is frequent in female subjects being treated with oral contraceptives. Other risk factors are taking anabolic steroids and some metabolic diseases. The discovery of a hepatic adenoma requires periodic checks.
When more than ten adenomas are present the term adenomatosis is used. Large-sized lesions (> 5 cm) have a potential risk of spontaneous rupture and bleeding within the lesion itself or within the abdominal cavity (i.p., resulting in the framework of hemoperitoneum).
Spontaneous breakage occurs more frequently in males who use anabolic steroids.
The treatment of choice for this type of lesion is surgical removal.
