What is the typical presentation of irritation fibroma?

Irritation fibromas typically present as soft, non-indurated, and movable masses. They are benign lesions that generally develop as a response to chronic irritation or trauma within the oral cavity, such as from dental prosthetics, rough teeth, or habitual biting of the cheek.

The soft consistency of irritation fibromas allows them to be movable upon palpation, and they usually do not exhibit signs of induration (hardening) that can indicate a more serious lesion. These benign growths can vary in size and are often asymptomatic, which aligns with the description of a soft and non-indurated mass.

The other options highlight characteristics that do not align with irritation fibromas: painful, ulcerated lesions or chronic inflammation with discharge suggest different conditions that involve more complex pathology, while a hard, fixed mass may indicate a neoplastic process rather than the benign nature of an irritation fibroma.
