The FP had seen many recalcitrant warts before, but rather than repeat the cryotherapy, he performed a shave biopsy to get a definitive diagnosis. (See the Watch & Learn video on “Shave biopsy.”) The biopsy revealed a well-differentiated squamous cell carcinoma (SCC).
This lesion may have started with a wart, as human papillomavirus (HPV) is both the cause of warts and a risk factor for cutaneous SCC. The FP referred the patient to a Mohs surgeon for complete excision of the SCC. He also provided counseling about sun avoidance, the consistent use of a hat outdoors, and the use of sunscreens when exposed to the sun.
