Chronic traumatic ulcers (CTUs) that do not heal may transform into oral squamous cell carcinoma (OSCC). This study highlights that non-healing CTUs (NHCTUs) can be considered potentially malignant disorders, especially on the tongue, warranting close follow-up.
Area of Science:
- Oral pathology
- Oncology
- Dental medicine
Background:
- Oral squamous cell carcinoma (OSCC) can arise from oral potentially malignant disorders (OPMDs) or de novo.
- Chronic traumatic ulcers (CTUs) are suspected but unconfirmed precursors to OSCC.
- Non-healing CTUs (NHCTUs) represent a subset of CTUs with persistent lesions.
Purpose of the Study:
- To describe the clinicopathological characteristics of non-healing CTUs (NHCTUs) that subsequently developed into oral squamous cell carcinoma (OSCC).
Main Methods:
- A retrospective cohort study was conducted from 2013-2019 at Facultad de Odontología Universidad Nacional de Córdoba.
- Patients with a provisional diagnosis of CTU were included.
- NHCTUs, defined as CTUs failing to heal after trauma removal, underwent biopsy for histological examination.
Main Results:
- Out of 107 CTUs, 32 were classified as NHCTUs.
- Two cases of NHCTU on the lateral tongue showed histological features of OSCC.
- These two individuals were non-smokers, non-drinkers, and had no other known OPMDs.
Conclusions:
- Non-healing CTUs (NHCTUs), particularly those on the tongue, carry a risk of malignant transformation into oral squamous cell carcinoma (OSCC).
- NHCTUs should be considered a potential oral potentially malignant disorder (OPMD) in certain cases.
- Regular follow-up of NHCTUs is crucial due to their low but significant malignant transformation potential.

The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
