STUDY ON CLINICAL FEATURES AND RESULTS OF HORI’S NEVUS TREATMENT BY THE PICO ND: YAG LASER AT CAN THO HOSPITAL OF DERMATO-VENEREOLOGY 2019 - 2020
Main Article Content
Abstract
Background: Hori’s nevus is an acquired pigmented lesion commonly appearing among middle-aged women. The treatment of Hori’s nevus improves the skin beauty and confidence for patients. Objectives: This study aims to describe clinical features and results of Hori’s nevus treatment at Can Tho hospital of dermato-venerology. Materials and Methods: A cross-sectional study was conducted on 62 patients having Hori’s nevus at Can Tho hospital of dermatovenereology from 4/2019 – 4/2020. The Pico Nd: YAG used wavelength of 1064 nm, fluence of 4 – 6 J/cm2 (283 – 424 mJ/mm2), spot size of 3 – 4 mm, frequency of 5 – 10 Hz. Patients had at least 4 times of treatment with 4 – 6 week intervals. Results: 100% female with the average age of 30.6 ± 8.2 and the onset age of 31.0 ± 9.0. The spreading skin area of 2 – 3 times contributed 58.1%. The prevalence of Hori nevus patients having postinflammatory hyperpigmentation degree of III by Rolfpeter-Zaumseil took 100%. The rate of participant getting Hori nevus color number of 27 by Von Luschan scale were 43.5%. Hori’s nevus mostly bilaterally located on the cheeks (96.8%). The good result of treatment of Hori’s nevus was 87.1%. There were under 20% patients getting side effects of redness skin and hemorrhage after 24 hours of treatment. Conclusions: Hori’s nevus treatment can be effectively achieved by using the Pico Nd:YAG laser.
