What is your diagnosis? A solitary purple papule on the arm—Answer
نویسندگان
چکیده
Kaposi sarcoma (KS) was first described by Kaposi in 1872. There are four clinical types of the disease: classic, endemic, epidemic and iatrogenic [1]. Iatrogenic KS develops in patients taking immunosuppressive treatment. Bluish-reddish coloration is seen in 84% of KS lesions in dermatoscopy. Rainbow pattern and scaly surface are other dermatoscopic features of KS (36% and 15%, respectively) [2]. Multicolored rainbow pattern is the most diagnostic appearance of KS in dermatoscopic evaluation and is associated with vascular lumen-rich histological sub-type [3]. This pattern can be rarely seen in the dermatoscopy of melanoma [4]. Congratulations to Dr. Arina Vashkevich (aavashk@mail. ru), who was the first to send us the correct answer!
