MEJIA-RODRIGUEZ, Silvia A; RAMIREZ-ROMERO, Verónica Susana; VALENCIA-HERRERA, Adriana  and  MENA-CEDILLOS, Carlos. Unilateral laterothoracic exanthema of childhood. Bol. Med. Hosp. Infant. Mex. [online]. 2007, vol.64, n.1, pp.65-68. ISSN 1665-1146.

The unilateral laterothoracic exanthema, also known as asymmetric peri flexural exanthema of childhood, is an erythematosus papular eruption, slightly or non pruriginous, of unknown etiology, even when most of the evidence support a probable viral origin. Clinically, it initiates on one side of the thorax, generally near the axilla, progressing centrifugally on the ipsilateral side of body and contra lateral side and eventually disappears without sequelae in a period of 4 to 6 weeks. There have been reports of approximately 300 cases in the literature. However, the majority of the authors agree that the lack of diagnosis is result of the lack of knowledge about this entity.

Keywords : Unilateral laterothoracic exanthema of childhood; symmetric peri flexural exanthema of childhood.
