Pityriasis rotunda: Report of a familial occurrence and review of the literature

Abstract: Pityriasis rotunda is an uncommon dermatosis characterized by multiple, widely distributed, strikingly circular hypopigmented or hyperpigmented patches that are slightly scaly It has been described in Oriental and black patients, usually in association with certain infective or malignant systemic diseases Pityriasis rotunda is rare in white patients and does not act as a marker of malignancy Our ultrastructural and histologic findings demonstrated that pityriasis rotunda is more closely related to congenital ichthyoses than ichthyosis vulgaris, contrary to previous reports On the basis of our studies and a review of the literature, it seems that two types of pityriasis rotunda exist with significant prognostic differences

Asymmetric periflexural exanthem of childhood: report of two new cases.

Abstract: A newly described exanthem of infancy consists of an eczematous or scarlatinltorm eruption that starts initially from one axillary fold and spreads unilaterally and centrifugally on the trunk and the proximal part of the upper limb. Minor lesions are infrequently present on the contralaterai side. The rash may be slightly pruritic and sometimes associated with a moderate regional lymphadenopathy. The appearance in small epidemics and the seasonal prevalence imply a viral agent as the probable origin. We report two new cases of this entity, which appears to be not so rare.
