Pityriasis Rosea Skin Findings and Clinical Course
Early lesions are broad based papules that subsequently develop a thin collarette of scale as the center of the papule desquamates. Lesions are salmon-colored on Caucasian skin and dark- brown on African American skin. Lesions are usually confined to the trunk and proximal extremities, often concentrated on the lower abdomen. The long axis of the oval lesions is oriented along skin lines reminiscent of drooping pine branches. Atypical cases do occur and may be confused with other disorders. A serologic test for syphilis should be considered in the right clinical setting, especially if lesions are present on the palms and soles.
