Abstract
Background: Pityriasis versicolor (PV) is a common superficial fungal infection caused by Malassezia species. It is particularly prevalent in warm and humid climates and characterized by pigmentary changes and fine scaling. Despite its benign course, recurrence is frequent and may affect quality of life.
Objective: To describe the clinical and epidemiological characteristics of pityriasis versicolor in northern Morocco and to assess associated risk factors, treatment patterns, and recurrence rates.
Methods: A cross-sectional descriptive study was conducted among 203 patients diagnosed or clinically suspected of PV in dermatology consultations in northern Morocco. A standardized questionnaire collected demographic, environmental, clinical, diagnostic, therapeutic, and recurrence data, as well as information regarding preventive behaviors and quality-of-life impact.
Results: The most represented age group was 25–34 years (37%). Females accounted for 52% of participants. Aggravation during hot and humid periods was reported by 73%. Hypopigmented macules were observed in 55% and fine scaling in 70%. The trunk (73%) and back (62%) were the most affected sites. Medical consultation was sought by 68% of participants; 66% received confirmed diagnoses. Topical antifungals were prescribed in 77% of cases. Complete resolution was reported in 47%, partial improvement in 40%. Recurrence occurred in 80% of cases. Most participants (77%) expressed a need for improved information and preventive guidance.
Conclusion: Pityriasis versicolor is highly prevalent among young adults in northern Morocco and is strongly associated with warm, humid conditions. High recurrence rates highlight the importance of preventive strategies and patient education.
