Frequency of different types of facial melanoses referring to the Department of Dermatology and Venereology, Nepal Medical College and Teaching Hospital in 2019, and assessment of their effect on health-related quality of life.

Background: Abnormalities of facial pigmentation, or facial melanoses, are a common presenting complaint in Nepal and are the result of a diverse range of conditions.

Objectives: The objective of this study was to determine the frequency, underlying cause and impact on quality of life of facial pigmentary disorders among patients visiting the Department of Dermatology and Venereology, Nepal Medical College and Teaching Hospital (NMCTH) over the course of one year.

Methods: This was a cross-sectional study conducted at the Department of Dermatology and Venereology, NMCTH. We recruited patients with facial melanoses above 16 years of age who presented to the outpatient department. Clinical and demographic data were collected and all the enrolled participants completed the validated Nepali version of the Dermatology Life Quality Index (DLQI).

Results: Between January 5, 2019 to January 4, 2020, a total of 485 patients were recruited in the study. The most common diagnoses were melasma (166 patients) and post acne hyperpigmentation (71 patients). Quality of life impairment was highest in patients having melasma with steroid induced rosacea-like dermatitis (DLQI = 13.54 ± 1.30), while it was lowest in participants with ephelides (2.45 ± 1.23).

Conclusion: Facial melanoses are a common presenting complaint and lead to substantial impacts on quality of life. Accurate diagnosis and management can prevent or treat many facial melanoses, including those that lead to substantial loss of quality of life, such as melasma with steroid induced rosacea-like dermatitis. Health care systems in low and middle-income countries should dedicate resources to the identification, prevention and treatment of these conditions to improve quality of life.
