Chronic Tongue Lesions: Causes and Concerns - Otolaryngology

Chronic tongue lesions can be a source of concern for many individuals, especially when they persist over an extended period, as in your case. The description of your tongue lesion—located on the right side, extending from the root to the tip, and characterized by intermittent ulceration—raises several important considerations regarding potential causes and implications.

First, it is essential to understand that tongue lesions can arise from a variety of etiologies, including but not limited to infections, inflammatory conditions, autoimmune disorders, and malignancies. Given that your lesion has been present for approximately four years and shows variability in size and severity, it is crucial to consider both benign and more serious conditions.

1. Benign Causes:
- Geographic Tongue: This is a benign condition characterized by irregular patches on the tongue's surface, which can sometimes appear ulcerated. It is often asymptomatic but can cause sensitivity to certain foods.

- Aphthous Stomatitis: Commonly known as canker sores, these painful ulcers can recur and may be triggered by stress, certain foods, or nutritional deficiencies.

- Lichen Planus: This inflammatory condition can affect the oral mucosa, leading to white patches or ulcerations on the tongue. It may cause discomfort and sensitivity.

2. Infectious Causes:
- Fungal Infections: Conditions like oral thrush (candidiasis) can lead to white patches and discomfort on the tongue.

- Viral Infections: Herpes simplex virus can cause painful lesions on the tongue and oral cavity.

3. Malignant Conditions:
- While less common, persistent lesions that do not heal and show signs of enlargement should be evaluated for potential malignancy, such as squamous cell carcinoma. Early detection is crucial for better outcomes.

4. Autoimmune Disorders: Conditions like lupus or Sjögren's syndrome can lead to chronic oral lesions and sensitivity.

Given the chronicity of your lesion and its tendency to expand, it is advisable to seek a thorough evaluation from a healthcare professional, preferably an oral surgeon or an otolaryngologist (ENT specialist). They may recommend diagnostic procedures such as a biopsy to determine the exact nature of the lesion. A biopsy can provide critical information regarding whether the lesion is benign, inflammatory, or malignant.

In addition to a physical examination, your healthcare provider may inquire about your medical history, any associated symptoms (such as changes in taste, difficulty swallowing, or systemic symptoms like weight loss), and any potential risk factors (such as tobacco use or a history of HPV infection).

In summary, while many tongue lesions are benign and self-limiting, the chronic nature and expanding characteristics of your lesion warrant further investigation to rule out serious conditions. Early diagnosis and appropriate management are key to addressing any underlying issues and alleviating your concerns. Please consider scheduling an appointment with a specialist to discuss your symptoms in detail and explore the best course of action.
