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.
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.
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.
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.
花斑糠疹是一种常见的皮肤真菌感染，可导致皮肤上形成鳞屑性和变色的小皮损。本研究的主要目的是描述花斑糠疹患者的临床和真菌学特征以及诱发因素。
在这项基于医院的前瞻性观察性横断面研究中，纳入了所有年龄临床上怀疑患有花斑糠疹皮损的患者。在详细询问病史并进行全面临床检查后，取皮肤刮屑在光学显微镜下用10%氢氧化钾（KOH）进行检查。刮屑还进行了培养检查。
本研究共纳入113例患者[78例（69.0%）男性；35例（31%）女性]。共有87例（76.9%）患者来自农村地区。65例（57.5%）患者从事户外工作，38例（33.6%）患者有花斑糠疹家族史阳性。66例（60%）患者报告有复发情况。分别有36例（31.8%）和24例（21.1%）患者有多汗和油性皮肤。22例（19.4%）患者有穿着紧身衣物史。胸部、背部和肩部受累的患者分别为36例（31.8%）、22例（19.4%）和8例（7.0%）。97例（85.8%）患者出现色素减退性皮损。分别有60例（53.1%）和53例（46.9%）患者观察到斑块和斑疹。共有27例（23.8%）患者报告有轻度瘙痒。共有79例（69.9%）患者KOH检查阳性但培养阴性，而26例（23.0%）患者KOH检查和培养均阳性。8例（7.0%）患者KOH检查和培养均阴性。
花斑糠疹在年轻成年人和男性中更为常见，最常见的表现为色素减退性皮损。在我们的研究人群中，大片状皮损比斑疹更为常见。大片状皮损患者的瘙痒比斑疹患者更严重。
