Precancerous skin lesions

Last updated: April 5, 2023

Summarytoggle arrow icon

Precancerous skin lesions refer to various dermatological growths that are at an increased risk of developing into skin cancer. Typical precancerous skin lesions include lentigo maligna, which may develop into malignant melanoma, and actinic keratosis, which may develop into squamous cell carcinoma. There is also a risk of leukoplakia – presenting in the oral cavity as white plaques – progressing to squamous cell carcinoma. Bowen disease and erythroplasia of Queyrat are less common types of precancerous skin lesions and are often associated with the human papillomavirus (HPV). To prevent malignant transformation, surgical excision is usually the treatment of choice.

Although Bowen disease affects the skin and erythroplasia of Queyrat affects the mucous membrane, the precancerous lesions are histopathologically identical.
