Abstract

|
|
|
Pityriasis rotunda is an uncommon dermatosis characterized by asymptomatic, multiple, widely distributed, round or oval-shaped, hyperpigmented or hypopigmented, fine, scaly patches. They typically involve the abdomen, the trunk and extremities. Histopathologic findings are consistent with ichthyosis vulgaris, such as hyperkeratosis, hypogranulosis or agranulosis, hyperpigmentation of the basal layer in epidermis, and perivascular lymphohistiocytic infiltration in the dermis. Although the etiology of the disease remains unknown, it has been associated with a variety of underlying systemic diseases including infectious diseases, hormonal disorders, malignancies, and chronic disorders. One clinical case has been reported about the occurrence of the disease during pregnancy of a 24-year-old african woman, but there is only one reported case of exacerbation of the disease during pregnancy in Korea. Herein, we report a case of pityriasis rotunda occurring during pregnancy.
