Extracellular Matrix Remodeling in Actinic Cheilitis and Lip Squamous Cell Carcinoma: A Cross‐Sectional Study

Oral Diseases, EarlyView.
ABSTRACT Background Actinic cheilitis is a precursor to lip squamous cell carcinoma. How ultraviolet‐induced stromal degeneration relates to invasion‐related extracellular matrix markers remains unclear. This study investigated basophilic degeneration of collagen, solar elastosis, fibronectin, tenascin‐C, and podoplanin in both lesions.
