Pityrosporum folliculitis, Inflammatory skin disorder, Differential diagnosisAbstract
Pityrosporum folliculitis (PF) is an inflammatory skin disorder that presents as a pruritic, follicular papulopustular eruption distributed
on the upper trunk of young to middle aged adults. Herein, we report a 21-years old healthy male presented with 2 weeks
history of persistent itchy skin lesions. Skin examination revealed multiple and extensive monomorphic papules and pustules
with erythematous hallow on his forehead, chest, back, neck and upper arms. No history of associated fever or arthralgia. Hair,
nails and mucous membranes were normal. Skin smear from a pustule for potassium hydroxide (KOH) was negative for hyphae
and yeast. The lesions disappeared 2-weeks after ketoconazol shampoo once daily plus oral fluconazole 100 mg cap once daily.
On the basis of the above clinical findings, a diagnosis of Pityrosporum folliculitis was made.
