Anesthetic blister induction to identify biopsy site prior to Mohs surgery.

Background: Wrong-site surgery in dermatology often occurs due to difficulty finding the initial biopsy site prior to Mohs surgery. Patients frequently present for Mohs surgery weeks to months following the initial biopsy site. Visualization of the biopsy site may become difficult at presentation due to healing.

Reflectance confocal microscopy criteria for squamous cell carcinomas and actinic keratoses.

Objective: To identify criteria for the diagnosis of squamous cell carcinoma (SCC) and actinic keratosis (AK) by in vivo reflectance confocal microscopy (RCM).

Design: Prospective RCM imaging of lesions suspected clinically and/or dermoscopically to be SCC or AK, followed by RCM assessment of the biopsy-proven SCCs and AKs.

Setting: Private skin cancer clinic, Plantation, Florida.
