Malassezia folliculitis is an under-recognizedentity commonly affecting the face and upper trunk. Clinical picture mimics acne vulgaris and diagnosis is challenging at times. 10% potassium hydroxide examination is usually performed to confirm the diagnosis. This study sought to describe the dermoscopic features in Malassezia folliculitis. Patients diagnosed clinically with Malassezia folliculitis and confirmed by 10% potassium hydroxide preparation were included in the study. Dermoscopy was performed with a videodermatoscope [Dinolite AM413ZT; Polarising] from the most representative lesion. A total of 45 patients (M:F = 1:0.8 ) were recruited. All patients had monomorphic papulo-pustular lesions. Itching was present in 64.4% patients. Dermoscopy reveled folliculocentricity (100%), perilesional background erythema (100%), dotted/linear/tortous vessels (88.9%), dirty white scaling (77.8%), hypo pigmentation of hair follicle (64.4%), coiled/looped hairs (57.8%) and broken hairs (13.3%). In conclusion, dermoscopy shows typical features in Malassezia folliculitis and can serve as a office based tool for identification of this entity.

A niche in the context of microorganisms defines the specific ecological role or habitat inhabited by microbial species within an ecosystem. For the human commensal Malassezia, the skin surface is considered its primary niche, where it adapts to the skin environment by utilising lipids as its main carbon and energy source. However pathogenic characteristics of Malassezia include the production of allergens, immune modulation and excessive lipid utilisation, which result in several diseases such as pityriasis versicolor, seborrheic dermatitis, Malassezia folliculitis and atopic dermatitis.

folliculitis (MF) is a fungal infection that often presents with pruritic follicular papules and pustules, primarily affecting the upper body. Due to its clinical similarity to bacterial folliculitis, misdiagnosis and delayed treatment are common. In this report, we present the case of a 16-year-old male who developed persistent pruritic papules on his upper back and chest, initially misdiagnosed as bacterial folliculitis.
