What is the Difference Between Tobacco Pouch Keratosis and Leukoplakia?

Tobacco pouch keratosis and leukoplakia are two different oral mucosa diseases that can lead to mouth cancers. Both conditions are more common in males than females and can be due to tobacco usage. However, there are key differences between the two:

• Location: Tobacco pouch keratosis mainly occurs in the buccal sulcus and labial sulcus, while leukoplakia mainly occurs in the buccal mucosa, tongue, and gingiva.
• Causes: Tobacco pouch keratosis develops on the oral mucosa in response to smokeless tobacco use, such as chewing tobacco or using snuff. Leukoplakia, on the other hand, develops on the oral mucosa due to repeated injury, whether from smoked, dipped, or chewed tobacco.
• Appearance: Tobacco pouch keratosis presents as a white, corrugated plaque on the oral mucosa. Leukoplakia is characterized by a predominantly white lesion of the oral mucosa that cannot be characterized as any other definable lesion.

Both conditions can be diagnosed through physical examination and tissue biopsies, and they are treated through surgical excision. While tobacco pouch keratosis is considered a precancerous lesion, it is said to have a lower risk of malignant transformation when compared to leukoplakia.
