Fibrous strands radiate from the scar and divide the lesion into nodules. Focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA) are benign hepatocellular tumors. Introduction Focal nodular hyperplasia (FNH) has traditionally been classified as a type of benign hepatocellular nodule, and is defined as a hyperplastic lesion caused by vascular anomaly and characterized by normal background liver, a grossly visible central scar, and histologically evident anomalous blood vessels and portal tract[1]. Focal nodular hyperplasia (FNH) is a rare benign disease of the liver and the second most common benign lesion in healthy, young and middle-aged women (1-4).The pathogenesis of this disease is unclear (5,6).Most researchers think that it is a reactive process of the liver to vascular damage or deformity. Histology shows typical dense fibrous tissue with relatively few cells. Histologically, Irritational fibroma demonstrates a reactive focal fibrous hyperplasia due to local irritation [1,2]. This bestselling reference gives direct access to a complete range of full-color clinical images and patient radiographs that illustrate the differentiating characteristics of lesions in the oral and maxillofacial region. In both conditions, the glands are lined by columnar-shaped epithelial cells instead of the normal single layer of cuboidal epithelial cells. DOI: 10.4103/0973-029X.141328. Focal fibrous hyperplasia (FFH), is a reactive, inflammatory hyperplastic lesion of the connective tissue [3].

As there exist certain clinical resemblance between squamous cell papilloma, fibrous focal hyperplasia and other mesenchimal tumors it is recommended to proceed, always, with removal and study. Comments: Focal fibrous hyperplasia or fibroma is considered the most common benign soft tissue growth in the oral cavity [1, 2].This lesion has a predilection for females, occurs in patients older than 30 years, is a few centimeters in diameter, pedunculated or sessile, and occurs frequently on the gingiva or buccal mucosa. Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases. When accompanied by inflammatory cells and/or oval cell proliferation, bile duct hyperplasia may be the consequence of a toxic insult. Week 245: Case 6.

Fibrous lesion of oral mucosa, painless, well-circumscribed, pedunculated, dark red color, nodular surface. Histologically, inflammatory fibrous hyperplasia is made up of a mass of hyperplastic connective tissue with dilated blood vessels, usually with chronic inflammatory cells such as lymphocytes and plasma cells, but it can also be made up of solid connective tissue with minimum to no inflammatory cells, the latter called fibrous hyperplasia. 3.
