Abstract
Background: Pityriasis versicolor (PV) is a common superficial fungal infection caused by Malassezia species, with higher prevalence in tropical climates.
Objective: To evaluate clinical patterns, distribution, associated conditions, and epidemiological factors of PV.
Methods: A cross-sectional study was conducted among 200 patients attending the dermatology outpatient department at Anugrah Narayan Magadh Medical College & Hospital, Gaya, between October 2020 and September 2022. Clinical data, family history, seasonal variation, and associated conditions were documented. KOH and Wood’s lamp examinations were performed in all patients.
Results: PV was most prevalent in the 2nd and 3rd decades of life (80.5%), with a male-to-female ratio of 1.5:1. Family history was present in 16%. The disease was asymptomatic in 59% and recurrent in 14.5%. Exacerbation occurred in 71.5% during summer, and sweating was a major provoking factor in 20%. The trunk (71%), face (30.5%), and neck (24%) were most frequently involved. Hypopigmented patches were the predominant lesions (62.5%), with clear margins in 79.5%. Associated conditions included acne vulgaris, immunosuppression, and infections. KOH examination was positive in all cases, while Wood’s lamp fluorescence was seen in 24.5%.
Conclusion: PV predominantly affects young adults, with summer exacerbation and sweating as key risk factors. Though mild, its recurrent nature and cosmetic impact make it a significant clinical concern in tropical regions.
