Core Tip

Core Tip: Adverse cutaneous reactions to vitamin K1 can occur; however, their diagnosis can easily be overlooked. Managing these reactions may be challenging for both patients and clinicians. Here we report a patient who developed a cutaneous allergic reaction to subcutaneous vitamin K1 that was successfully treated with herbal medicine, suggesting that Chinese medicine therapy may be a feasible way to treat adverse cutaneous reactions. We confirmed our clinical findings through physical examination, a skin biopsy, and immunohistochemical staining. We also conducted a literature review of eczematous-type reactions to clarify the possible pathogenesis and provoke new thinking regarding the clinical treatment of this disease.
