Abstract

Acquired dermal melanocytosis (ADM) is a benign condition characterized by localized hyperpigmented macules commonly observed on the face. As ADM involving the nasal mucosa is rare, its treatment can pose a challenge. We report a case of a 32-year-old female with a 5-year history of a hyperpigmented macule on her left nostril caused by habitual nose-picking. It was diagnosed as ADM based on clinical and histopathological findings. The patient underwent eight sessions of 1,064 nm Q-switched Nd:YAG laser treatment, resulting in a significant improvement in pigmentation without any adverse events. At the four-month follow-up, no signs of relapse were observed. Thus, the Q-switched Nd:YAG laser therapy appears to be a safe and effective option for treating ADM on the nostrils.
