Pityriasis versicolor is clinically characterized by slightly scaly, hyper- or hypopigmented macules usually located on the chest, shoulders, back, and arms. Rare cases of atypical locations of pityriasis versicolor have been described, such as groins, penis, and perineum. We present three cases of pityriasis versicolor located exclusively on the submammary folds, pubis, and inguinal folds (the latter in an 11-year-old girl), respectively. Considering both the location and clinical presentation of pityriasis versicolor in these three patients, we think the diagnosis of erythrasmoid pityriasis versicolor is acceptable. Differential diagnosis with erythrasma must be taken into consideration. Therefore, mycological and bacteriological examinations are necessary for a correct diagnosis and specific therapy.
花斑糠疹的临床特征为通常位于胸部、肩部、背部和手臂的轻度鳞屑性、色素沉着过度或色素沉着不足的斑疹。已有花斑糠疹非典型部位的罕见病例报道，如腹股沟、阴茎和会阴。我们分别报告了3例花斑糠疹，分别仅位于乳房下皱襞、耻骨和腹股沟皱襞（后者见于一名11岁女孩）。考虑到这3例患者花斑糠疹的部位和临床表现，我们认为诊断为红癣样花斑糠疹是可以接受的。必须考虑与红癣进行鉴别诊断。因此，进行真菌学和细菌学检查对于正确诊断和特异性治疗是必要的。
