Clinico-epidemiological study of pityriasis versicolor in a rural tertiary care hospital

BACKGROUND: Pityriasis versicolor (PV) is a common and chronic superficial mycosis seen in all age groups and characterized by dyspigmented lesions caused by dimorphic lipophilic yeast. AIM: The aim of the study was to study the clinical aspects, prevalence, and demographic data of patients with PV in Baghdad City. MATERIALS AND METHODS: Total of 175 patients with PV attending the department of Dermatology at Al Imamein Al Kadhemein Medical City and Alkarama Teaching Hospital in Baghdad city from January 2019 to January 2020 were included in this study. Diagnosis was done clinically. Interviews with patients were done using a questionnaire designed by the researcher. RESULTS: From 175 patients with PV, there were 71 (40.6%) males and 104 (59.4%) females. The mean age was 23.97 ± 10.25 years. The majority of cases 71 (40.6%) were 21–30 years. Eighty-one (46.3%) patients were presented from April to June. Itching presented in 21.7% of patients. The majority of patients (48.6%) presented with hyperpigmented type. Neck was the most common site to be involved in 101 patients (57.7%). CONCLUSION: The most common age group affected was 21–30 years. Females were commonly affected. Peak incidence was observed in April–July months. Neck was the most common site affected. Hyperpigmented type is more commonly presented type.

“…In our study, the most commonly affected age group was from 21 to 30 years of age which coincides with other studies. [ 8 9 10 11 ] This is explained by the role of sebum and hormone in young adults. Increased activity of pilosebaceous glands at puberty leads to increased sebum production and thus provides a lipid rich environment for the growth of Malassezia species.…”

“…Our study population was predominated by male population in accordance with others. [ 8 9 12 ] However, in another study, females from fishery community had higher rate of infection than males. [ 13 ] We observed females presenting with face involvement more commonly whereas males had more lesions on chest and abdomen.…”

Background and Objectives: Pityriasis versicolor is a common fungal infection of the skin which leads to the formation of scaly and discoloured small lesions on skin. The main objective of this study is to describe clinical and mycological characteristics and the predisposing factors in patients with pityriasis versicolor. Material and Methods: In this prospective, observational, hospital-based cross-sectional study, patients of all ages with clinically suspected lesions of pityriasis versicolor were included. After detailed history and thorough clinical examination, skin scrapings were examined with 10% potassium hydroxide (KOH) under light microscope. The scrapings were also subjected to culture examination. Results: A total of 113 patients [78 (69.0%) male; 35 (31%) female] were included in the study. A total of 87 (76.9%) patients were from rural area. Outdoor occupation and positive family history of pityriasis versicolor was present in 65 (57.5%) and 38 (33.6%) patients, respectively. Recurrent episodes were reported by 66 (60%) patients. Excessive sweating and oily skin were seen in 36 (31.8%) and 24 (21.1%) patients, respectively. History of occlusive clothing was present in 22 (19.4%) patients. Chest, back, and shoulders were affected in 36 (31.8%), 22 (19.4%), and 08 (07.0%) patients, respectively. Hypopigmented lesions were seen in 97 (85.8%) patients. Patches and macules were observed in 60 (53.1%) and 53 (46.9%) patients, respectively. A total of 27 (23.8%) patients reported mild prutitus. A total of 79 (69.9%) patients were KOH positive and culture negative, whereas 26 (23.0%) patients were KOH as well as culture positive. Eight (7.0%) patients were both KOH and culture negative. Conclusion: Pytiriasis versicolor is more common in young adults and males with the most common presentation of hypopigmentation lesions. In our study population, presentation with large patches was more common than macular lesions. Pruritus was more in patients with large patches than those with macules.

“…Various other studies have also reported the occurrence of pityriasis versicolor most commonly in this age group. [6][7][8][9][10][11] This may be explained by the fact that there is increased sebum production during this period and Malassezia being lipophilic, affects these individuals more often. Males (70%) outnumbered females (30%) in the study population.…”

“…Crespo Erchiga et al and Tabaseera N et al reported association of seborrhoeic dermatitis in 40% and 31.4% of patients respectively. 8,22 Majority of the patients had blood group A (52%), followed by blood group O (38%). This is contrary to the study by Kareema et al, in 2014, in which blood group O (74%) was most commonly associated followed by blood group A (13.9%) and blood group B in 10.7% of patients.…”

Background: Pityriasis versicolor, a chronic superficial fungal infection caused by lipophilic yeasts of the genus, Malassezia is a common infection in the tropical and subtropical regions. Objective was to study the epidemiology, clinical presentation, associations, etiological agents and clinico-mycological correlation of pityriasis versicolor.  Methods: Hundred patients with clinical diagnosis of pityriasis versicolor who attended the mycology out-patient (OP) clinic between September 2014 and August 2015 were enrolled. Skin scrapings from these patients were subjected to 10% potassium hydroxide (KOH) and culture.Results: Out of the 100 patients with pityriasis versicolor (PV), 70% were males and 30% were females and the most affected age group was between 21-30 years (43%). The youngest age affected was a 13 years old male while the oldest was a 65 years old male. Duration of the infection ranged between 1 month to 6 months in 65% while it was more than 1 year in 9% of patients. Recurrence was observed in 35% of them. Back was the most common site (48%) to be involved. Seventy percent of patients had more than 30% body surface area involvement. Achromic type of PV was the most common clinical presentation in 68% of patients. Out of the 76 isolates, Malassezia globosa was the predominant isolate (48.7%), followed by M. sympodialis (25%), M. furfur (10.5%), M. restricta (7.9%) and M. obtusa (6.6%).Conclusions: Achromic type of PV is the most common clinical presentation. Malassezia globosa is the most common etiological agent of pityriasis versicolor.
