Oral submucous fibrosis: an update.

Wollina U, Verma SB, Ali FM, Patil K - Clin Cosmet Investig Dermatol (2015)

Bottom Line: OSF is a diagnosis based on clinical symptoms and confirmation by histopathology.Surgery may be necessary in advanced cases of trismus.Prevention is most important, as no healing can be achieved with available treatments.

ABSTRACT
Oral submucous fibrosis (OSF) is a premalignant condition caused by betel chewing. It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments.

Mentions: The initial pathology of OSF is characterized by mixed inflammation and edema, and large fibroblasts (Figure 9). Later, collagen bundles with early hyalinization are seen, and the inflammatory infiltrate contains lymphocytes and plasma cells, occasionally resembling lichenoid mucositis.88
