Abstract
Background: Exosomes have gained attention for their potential in skin rejuvenation. Currently, most exosome products are available for topical administration, and the use of subdermal injection as a route of administration has not been approved. Aims: The purpose of this case report is to describe a case of skin necrosis that occurred following an intradermal injection of lyophilized exosomes. Materials and Methods: We hereby report a case of a middle-aged man who experienced adverse effects after receiving an intradermal injection of lyophilized exosomes. Multiple injections of an exosome product were administered to treat enlarged facial pores. Shortly after the injection, the patient felt pain and noticed several dark red bumps. Three days after injection, the lesions transformed into palpable, painful, non-blanchable purplish papules and nodules, accompanied by central, tiny crusted erosions. The residual product was injected into the upper arm using an intradermal method. Similar lesions also appeared, and a skin biopsy showed necrotic keratinocytes, leukocytoclastic vasculitis, and eccrine necrosis. Results: There are few reports available regarding complications, especially those related to intradermal exosomes. These complications include multiple foreign-body granulomatous reactions at the injection sites. In our case, oral prednisolone was administered for a duration of 7 days. After the treatment, the lesions exhibited notable improvement, eventually leaving post-inflammatory hyperpigmentation. Conclusion: Utilizing exosomes through unapproved methods should be avoided due to the possibility of adverse reactions that could cause aesthetic issues.
