GIRALDI, Susana et al. Granular parakeratosis: a report of six cases in children. An. Bras. Dermatol. [online]. 2006, vol.81, n.1, pp. 59-64. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962006000100008.
Granular parakeratosis is an alteration of keratinization that was first described in adults. It is characterized by hiperkeratotic plaques and papules in intertriginous areas. The authors describe six cases of granular parakeratosis in children. One patient had lesions on the buttocks; two children presented papules in both axillae and cervical region (presentations never described before in the literature). The remaining three patients presented with lesions in the inguinal folds. Review of the literature and discussion on the pathogenesis of this rare dermatosis are presented.
