Wart on scalp
A 35-year-old man presented to his family physician (FP) with a wart on his scalp that did not go away despite multiple treatments with cryotherapy and topical salicylic acid over the previous year.
What’s your diagnosis?
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.
