Detailed answer

Oral mucosal lesions or ulcers are not commonly associated with hyperpigmentation. Hyperpigmentation refers to the darkening or increased coloration of the skin in certain areas. It is usually caused by factors such as sun exposure, hormonal changes, inflammation, or injuries to the skin. Oral mucosal lesions or ulcers, on the other hand, are characterized by sores or abnormalities in the mouth. They can be caused by various factors, including infections, trauma, autoimmune diseases, or irritants. However, hyperpigmentation is not a typical symptom of these conditions. If you are experiencing hyperpigmentation or oral mucosal lesions or ulcers, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
