Hyperpigmentation in lesions of tinea versicolor has previously been reported to be a result of the effects of the fungus Pityrosporon orbiculare on melanosome formation and distribution. Examination of biopsy specimens from lesions of hyperpigmented tinea versicolor involving vitiliginous skin reveals an absence of melanosomes and melanocytes. Reddish-tan and fawn-colored hyperpigmentation in tinea versicolor of this type is not due to melanin pigment. The possible nature of the pigmentation that delineates hyperpigmented tinea versicolor from normal skin is discussed.
先前有报道称，花斑癣皮损中的色素沉着是由圆形糠秕孢子菌对黑素小体形成和分布的影响所致。对累及白癜风皮肤的色素沉着型花斑癣皮损的活检标本进行检查，发现不存在黑素小体和黑素细胞。这种类型的花斑癣中红棕色和淡褐色色素沉着并非由黑色素所致。本文讨论了色素沉着型花斑癣与正常皮肤之间色素沉着的可能性质。
