Abstract

BACKGROUNDCutaneous biopsy sites are often difficult to discern or are frequently misidentified when patients present for the treatment of skin cancers. This frustrating situation can lead to delays in treatment and wrong site surgeries. Current methods aiming to prevent this situation are not perfect.OBJECTIVEThis study seeks to determine the efficacy of ultraviolet-fluorescent tattoos in facilitating the correct identification of suspected nonmelanoma skin cancer biopsy sites.METHODSIn this prospective cohort, 51 shave biopsy sites were tattooed with ultraviolet-fluorescent ink in a series of 31 patients suspected of having a cutaneous malignancy. At the time of follow-up, the ability of the patient and the physician to identify the correct site with and without ultraviolet illumination of the tattoo was recorded. Visibility of the tattoo was graded before and after treatment.RESULTSPatients could not positively identify their biopsy site in 35% of cases. In 7% of cases, physicians could not confidently identify the site without the aid of ultraviolet illumination. In conjunction with tattoo illumination, physicians confidently identified the site in 100% of the cases. No adverse events occurred.CONCLUSIONUltraviolet-fluorescent tattoos offer a safe and reliable means of accurately marking cutaneous biopsy sites.
