Abstract:
Pityriasis rotunda is a rare disease characterized by round to oval, sharply defined, hypopigmented or hyperpigmented, scaly patches of variable number and size located trunk and extremity. The etiology is unknown but it has been associated with a variety of systemic illnesses, such as tuberculosis, malnutrition and malignancy. The first case was a 28-year-old male who presented with a 2-year history of multiple round shaped hyperpigmented patches on the trunk. The second-case was a 38-year-old female who presented with a 2-month history of circular, sharply defined multiple patches with ichthyosiform scaling on the trunk. Both patients had no systemic disease or familial history. We experienced 2 cases of pityriasis rotunda on the trunk without underlying systemic illnesses or familial association.
