Abstract
|
|
|
|
Pityriasis rosea, first described by Gilbert in 1860, is a fairly common dermatosis. The exact cause of pityriasis rosea is not known. The earliest clinical finding of a typical case is a herald patch, which is usually on the trunk, and scaly and erythematous daughter macules, which is distributed along the skin cleavage line, such as the ‘Christmas tree pattern’. This may be accompanied by Itching. Atypical cases of pityriasis rosea, such as palmoplantar, unilateral, vesicular and inverse forms, have also been reported. There is no difference between typical and atypical cases regarding the presence of a herald patch and/or symptoms. Differences between typical and atypical cases lie in the distribution of skin lesions and the characteristics of daughter macules. Hands and feet, including palms and soles, are rarely involved in pityriasis rosea. Moreover, there are no reported pathologic findings of pityriasis rosea of the palms and soles, even in atypical distributed pityriasis rosea case reports. Here, we report atypical case of pityriasis rosea with palmoplantar involvement with pathologic reports.
