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.
