| Popis: | Background Pityriasis rotunda is a rare skin disease characterized by the presence of multiple, round or oval, sharply demarcated hyperpigmented scaly patches. It has been described in Japan, South Africa, and in some other countries. The cause of pityriasis rotunda is usually idiopathic but may be associated with certain internal malignancy or systemic diseases. Objective The aim of this study is to describe this rare entity in Jordan in a retrospective study during the last 10 years. Jordan, as a Middle Eastern country, had no previous reports about this rare disease. In addition, the intention was to report any systemic association with the disease. Some of the cases were examined by dermoscopy. No previous reports documented dermatoscopic features of the disease. Results We could report 23 cases during the last 10 years. Eighteen cases were females and five males, in an age range of 9-38 years. There were three familial cases. The dermatoscopic findings were well demarcated, hyperpigmented with brownish patches with polygonal scales. These scales were more defined, not homogeneous in color, and separated from each other by paler stria. Conclusions The cases of the study seem to indicate the rarity of the disease in Jordan. Our case fits neatly into the benign form of the disease with lack of association with any underlying diseases. |
