Monsel solution is a hemostatic agent used in minor surgical procedures. It scleroses blood vessels by depositing ferric salts that precipitate proteins. Rarely, these deposits remain visible in the skin creating a Monsel tattoo. Herein we compare 3 methods used to treat a Monsel tattoo.
A 34-year-old man underwent a shave biopsy on his back. Monsel solution was applied for hemostasis. Histologic analysis showed an intradermal nevocellular nevus with clear margins. Two months later, the patient presented with a 1.2 × 1.0-cm brown patch over the entire biopsy scar.
