A patient has a tongue that is sticking out with an unusual fold but no redness. What could be a probable cause?

• A. Squamous cell carcinoma
• B. Lichen planus
• C. Benign migratory glossitis
• D. Previous laceration

Answer: (D)

In cases where a patient presents with a tongue that is sticking out and features an unusual fold without signs of redness, it is most indicative of a previous laceration. A laceration can lead to localized tissue changes, resulting in alterations in the appearance of the tongue, such as folding or sticking out due to scarring or healing processes. These changes can occur without inflammation, which is consistent with the absence of redness.

Other conditions, while they can cause changes in the tongue, typically present with additional symptoms or characteristics that do not match the clinical presentation described. For instance, squamous cell carcinoma often shows associated features such as redness, swelling, or lesions. Lichen planus typically presents with a lace-like pattern on the mucosa and may involve inflammation, while benign migratory glossitis usually features distinct patches and can present alongside erythema. These conditions would likely demonstrate more pronounced symptoms that are not evident in this scenario.
