title: Pityriasis Rotunda: A Case Report of Familial Disease in an American-Born Black Patient.
abstract: Pityriasis rotunda is an uncommon dermatosis with an unusual geographic and racial distribution. The skin disorder is characterized by sharply defined, perfectly circular, scaly patches with no inflammatory changes. Notably, it may be associated with underlying malignancy or chronic infection. We report an uncommon familial case in an American-born female.
