<p>Combined nevi are defined as the presence of 2 or more melanocytic cell groups within one lesion. They now refer to all cases of combinations of benign melanocytic nevus, including nevus cell nevi, Spitz nevi, and other melanocytic tumors, as well as blue nevi. In previous reports, treatment options for combined nevus primarily include surgical excision, laser therapy, cryotherapy, and combination therapy. However, there are no established guidelines for selecting the most appropriate treatment. A treatment for a combined nevus should be selected based on the histopathological structure of the combined nevus. On the other hand, laser therapy for combined nevi affects only blue nevus with melanocytosis and nevus spilus. Considering this background, we devise a treatment flowchart for a combined nevus against a blue nevus background. And we adapted this flowchart to two cases of combined nevus and underwent a combination therapy of excision and laser treatment, and neither case appeared to have any complications(e.g., postoperative hyperpigmentation, ectropion) and didn’t recur. The combination therapy of surgical excision and laser treatment is one of the best treatments for combined nevus, considering the cosmetic aspect. We propose a treatment selection flowchart for combined nevus against a blue nevus background.</p>
