When removing a seborrheic keratosis lesion using liquid nitrogen, what is an accurate statement regarding the procedure?

• A. Do not use lidocaine as it may potentiate bleeding.
• B. Pinch the skin taut together.
• C. Use gel foam to control bleeding.
• D. This should only be performed by a dermatologist.

Answer: (C)

Using gel foam to control bleeding is an accurate statement regarding the procedure for removing a seborrheic keratosis lesion using liquid nitrogen. During the cryotherapy process, the application of liquid nitrogen can lead to localized tissue damage and potential capillary disruption, which may cause bleeding in some patients. Gel foam, an absorbable sponge material, can be effectively utilized to help manage this bleeding by providing a physical barrier and promoting hemostasis in the area post-procedure.

This technique is useful in ensuring a clean procedure, reducing the risk of complications, and enhancing patient comfort by minimizing bleeding during and after the removal of the lesion. Other options may not align with the standard practices or recommendations for this procedure; for example, certain techniques such as applying excessive tension to the skin or concerns about the necessity of specialist intervention might not be needed in routine cases handled in primary care settings by trained practitioners.
