Punch biopsies in tattooed skin: Complications and patient-reported outcomes

BackgroundDespite the popularity and usage of tattoos in modern society, various complications can occur such as allergic tattoo reactions, infections, tattoo removal complications and chronic granulomatous inflammatory tattoo reactions such as sarcoidosis. Histopathology of skin biopsies in tattoos is crucial in the diagnostic process of complications. As tattoos are frequently obtained for cosmetic reasons, cosmetic consequences of a skin biopsy in a tattoo are important. Remarkably, no studies have been performed regarding the consequences and expected outcome of taking a punch biopsy of tattooed skin.ObjectivesThe objective of this study is to report on the possible complications and patient-reported cosmetic outcomes after punch biopsies in tattooed skin. Specifically, this study aims to assess the impact on appearance, symptoms and psychosocial burden of biopsies in tattooed skin, using the SCAR-Q.MethodsPatients who underwent a punch biopsy of tattooed skin at the Tattoo Clinic in the Alrijne Hospital between 2021 and 2023 were included. To evaluate patient satisfaction of the biopsy scar the SCAR-Q and a questionnaire regarding the recovery of the punch biopsy was used.ResultsThe final cohort consisted of 50 patients. Across all scales, the median scores on the SCAR-Q questionnaire were consistent with the maximum score. Patients scored significantly better on the appearance scale when the biopsy was taken longer than 8 months ago. Two-third of the patients reported no postbiopsy symptoms, with the remainder experiencing itch, pain or redness, which typically resolved within 10 days (88%). Remarkably, 42% of the patients reported the biopsy scar was not visible on the skin anymore. Scars on the lower extremities and trunk were significantly more frequently visible, as well as scars among patients aged 40 and above.ConclusionsThis study demonstrates that the cosmetic and psychological impact of punch biopsies in tattooed skin is minimal and the recovery is fast with minimal symptoms. For this reason, biopsies of tattooed skin should not be avoided in the diagnostic process. The objective of this study is to report on the possible complications and patient reported cosmetic outcome after punch biopsies in tattooed skin. Fifty patients with tattoo complications were included. This study demonstrates that the cosmetic and psychological impact of punch biopsies on tattooed skin is minimal, with fast recovery and minimal symptoms. Remarkably, 42% of the patients reported the biopsy scar was not visible on the skin anymore. In conclusion, biopsies of tattooed skin should not be avoided in the diagnostic process. image
