Basal cell carcinoma and collagenase

The interaction of connective tissue stroma and epithelial cutaneous cancer is an active area of investigation in dermatology. Studies summarized here explore the role of collagenase in basal cell carcinoma (BCC) invasiveness. Evidence is presented to support the role of a cytokine or cytokines secreted by BCCs that stimulate collagenase production by surrounding stromal fibroblasts. Prospects for further research in this area are proposed.
