Abstract

Background: Hori's nevus is an acquired pigmentation disorder of the face seen in middleaged women, presenting as patches of brown or black pigmentation on the face. Clearly describing the clinical features and evaluating the factors related to Hori's nevus will contribute to helping doctors understand the disease. Objectives: To describe clinical features and risk factors of hori’s nevus at Can Tho Hospital of Dermato-Venereology and FOB International Cosmetic Dermatology Institute. Materials and method: Case series report of 30 patients having hori’s nevus from 3/20214/2023. Results: A total of 30 patients, including 29 females and 1 male, were included in the analysis. 70% of the patients were aged older than 30 years. 13 subjects (46.7%) had yellow-brown lesions, while slate-grey lesions were observed in 36.7% of the rest, 20% showed blue-brown lesions. The location of lesions on both cheeks was found in 100% of cases; other areas such as the temples, forehead, eyelids, and base of the nose accounted for a low percentage. The proportion of subjects with dark pigmentation was positively correlated with patient age. Several factors, such as exposure to sunlight and protective factors such as wearing a mask and applying sunscreen, are associated with the degree of hyperpigmentation of Hori's nevus. Conclusion: Hori's nevus mainly affects the zygomatic area in subjects over 30 years old. Pigmentation levels of Hori’s nevus are related to age, sun exposure, and protective factors such as wearing a mask and applying sunscreen.
