New Health and Medicine Research Has Been Reported by Researchers at Sichuan University (Case report: Iatrogenic tattoos caused by skin marking pen in a postoperative patient).

A case report from Sichuan University in China highlights the risk of pigment retention caused by a skin marking pen used during surgery. The report describes a female patient who developed blue-black linear marks on her upper eyelid incision after undergoing blepharoplasty. Dermoscopy revealed scattered pigments in the epidermis, leading to a diagnosis of iatrogenic tattoo. The researchers recommend that practitioners inform patients about the risk of pigment retention and ensure proper cleaning of the ink after each invasive procedure. [Extracted from the article]
