Actinic comedonal plaque-variant of Favre-Racouchot syndrome: report of two cases.

The actinic comedonal plaque is characterized by papules, cysts and comedones forming a yellowish plaque in areas of chronic sun exposure skin. There are few reports in literature about this entity, considered a rare and ectopic form of Favré-Racouchot Syndrome. We report two cases of lesions located on forearms and thorax. Favré-Racouchot Syndrome is a condition usually restricted to the periorbital area; however, there are reports of similar findings in atypical locations, such as forearms and chest, which are known as actinic comedonal plaque. Ultraviolet radiation exposure is the main factor involved in its pathogenesis. The objective of this study was to provide accurate knowledge of this dermatosis and stimulate dermatologists to provide a correct diagnosis of the condition.
