Rate of growth-A novel surrogate marker for high-risk cutaneous squamous cell carcinoma? A case report and review of the literature.

Cutaneous squamous cell carcinoma (cSCC) is one of the most common nonmelanoma skin cancer worldwilde, with a more invasive growth pattern and higher potential to metastatize than basal cell carcinoma. Although several risk factors have been linked to a high metastatic potential of cSCC, no widely accepted classification system for this common subtype of cancer exists. Herein we report an emblematic case of rapidly growing and metastatic cSCC and discuss the rate of growth of the tumour (ROG) as novel prognostic high risk surrogate marker.
