The Two cases of Pityriasis Circinata ( Toyama )

Abstract

Pityriasis Circinata is a rare, symptomless, etiologically uncertain disease, but often associated with chronic illness such as Tuberculosis, diseases of uterus and ovaries. It was first described- in Japan by Toyama(1906), Matsura(1906), then reported in South Africa, France, England, Germany, and North-Africa. However, much more frequent evidence noted in Far East. Many authers agree that this condition is a specific localized type of acquired ichthyosis. This disease is manifested by strictly round scaly, light or dark brownish ichthyotic patches of variable number and diameter. Mainly distributed on trunk, and extremities with freedom of flexure. And having history of winter exacerbation and summer remission. These two cases of pityriasis Circinata are, although Toyama quoted 4 Korean patients reports and 2 cases of Manchuria, the first report in Korea, which have been associated with tuberculous empyema and meningitis, respectively.
