What type of oral condition could result from an injury on the tongue?

Bruising is a common outcome of trauma or injury to the tongue. When the tongue experiences physical trauma, such as biting or striking against a hard surface, blood vessels can rupture, leading to localized bleeding under the skin. This results in a discoloration or a bruise, which may vary in color and intensity depending on the severity of the injury and the time elapsed since the injury occurred.

In contrast, the other conditions listed arise from different causes. A granular cell tumor is a benign neoplasm of neural origin that forms in the oral cavity, but it is not directly caused by trauma. Fissured tongue, characterized by deep grooves or fissures, may be associated with various systemic conditions or genetic factors rather than a singular injury. Similarly, a fibroma is a benign tumor composed of connective tissue, typically resulting from chronic irritation or trauma over time rather than a single, acute injury. Understanding these distinctions can help in recognizing the proper diagnosis in clinical scenarios related to oral injuries.
