ReferencesFolliculitis は、毛包が感染または炎症を起こし、皮膚に膿疱や赤い隆起が生じる一般的な皮膚疾患です。多くの場合、毛包の細菌感染が原因ですが、真菌、ウイルス、または非感染性因子が関与することもあります。
Folliculitis is a common, generally benign, skin condition in which the hair follicle becomes infected/inflamed and forms a pustule or erythematous papule of overlying hair-covered skin. Most commonly, folliculitis is caused by bacterial infection of the superficial or deep hair follicle. However, this condition may also be caused by fungal species, viruses and can even be noninfectious in nature.

Malassezia (Pityrosporum) folliculitis はニキビのように見えますが、実際には真菌によって引き起こされる皮膚疾患です。一般的なニキビと間違われることが多いです。ニキビに似ていますが、通常のニキビ治療では完全に治らないことがあり、何年も続くことがあります。この状態は、皮膚内の特定の酵母菌が過剰に増殖することで発生します。免疫力の低下や抗生物質の使用などが症状を悪化させることがあります。主に胸部、背中、腕、顔に赤い隆起や吹き出物として現れます。経口抗真菌薬が最も効果的で、症状を迅速に改善できます。場合によっては、真菌感染と座瘡（にきび）を同時に治療する必要があることもあります。
Malassezia (Pityrosporum) folliculitis is a fungal acneiform condition commonly misdiagnosed as acne vulgaris. Although often associated with common acne, this condition may persist for years without complete resolution with typical acne medications. Malassezia folliculitis results from overgrowth of yeast present in the normal cutaneous flora. Eruptions may be associated with conditions altering this flora, such as immunosuppression and antibiotic use. The most common presentation is monomorphic papules and pustules, often on the chest, back, posterior arms, and face. Oral antifungals are the most effective treatment and result in rapid improvement. The association with acne vulgaris may require combinations of both antifungal and acne medications.

この記事では、ニキビと区別すべきさまざまなタイプの毛嚢炎を紹介します。対象となる疾患は、superficial pustular folliculitis (SPF)、folliculitis barbae および sycosis barbae、perifolliculitis capitis abscedens et suffodiens、folliculitis keloidalis nuchae、actinic folliculitis、eosinophilic pustular folliculitis (EPF)、malassezia folliculitis、そして epidermal growth factor receptor (EGFR) inhibitor‑induced papulopustular eruption です。
In this article, we introduce several special types of folliculitis which should be differentiated from acne, including superficial pustular folliculitis(SPF), folliculitis barbae and sycosis barbae, perifolliculitis capitis abscedens et suffodiens, folliculitis keloidalis nuchae, actinic folliculitis, eosinophilic pustular folliculitis (EPF), malassezia folliculitis and epidermal growth factor receptor(EGFR) inhibitor-induced papulopustular eruption.

多くの軽症例は自然に改善しますが、第一選択の治療は通常、局所軟膏です。mupirocin（ムピロシン）や neomycin/polymyxin B/bacitracin（ネオマイシン/ポリミキシンB/バシトラシン）軟膏などの局所抗生物質が処方されることがあります。必要に応じて経口抗生物質も使用されます。真菌性毛嚢炎（ピティロスポルム毛包炎）の場合は、経口抗真菌薬の投与が必要です。
○ 治療
ニキビ治療に用いられる薬は毛嚢炎にも有効です。過酸化ベンゾイルやアゼライン酸は毛嚢炎の病変に効果があります。化膿性の場合は、OTC の抗生物質軟膏も使用できます。
