Synopsis

The oral fibroma is a tumor-like mass of fibrous scar tissue caused by chronic trauma, typically a bite injury. There is no sex predilection and any age group may be affected.

The patient notices a painless (unless recently bitten) nodule that is located at sites easily bitten, such as the lower labial mucosa, lateral tongue, and buccal mucosa.

Differential Diagnosis & Pitfalls

  • Lipoma – These are generally yellow, but some contain more fibrous tissue and appear pink.
  • Oral papilloma
  • Granular cell tumor
  • Benign salivary gland tumor – These tend to be more firm and somewhat more deep-seated.
  • Malignant salivary gland tumor
  • Lobular capillary hemangioma (pyogenic granuloma) – Tends to be reddish-purple in color.
  • Soft tissue tumors (eg, neural tumors)
  • Medication-associated fibrous nodules – Occur in patients on cyclosporine after allogenic hematopoietic stem cell transplantation.
  • Mucocele – Dome-shaped, bluish, and fluid-filled, but they may become sclerosed, organized, and fibrotic over time.
  • Giant cell fibroma – A histologic variant, it has a papillary rather than smooth surface and is located mainly on the gingiva, tongue, and palate.
  • Cowden syndrome – Presents with not solitary but multiple fibrous nodules and papules in the oral mucosa with typical concomitant skin tumors.
