Abstract

Acroangiodermatitis is a benign vascular dermatosis resembling Kaposi’s sarcoma clinically and
histopathologically. This disease, also known as Pseudo-Kaposi sarcoma, is rare and can be confused
with Kaposi’s sarcoma. Our case was an 85-years-old female patient. Physical examination revealed
erythematous, diffuse varicose enlargements, increase in reticular veins, thinning of the skin and
edema were detected on the dorsalateral surfaces of both lower legs. As a result of clinical and
histopathological evaluation, the patient was diagnosed with pseudo-Kaposi’s sarcoma. Biopsy has an
important significance in the diagnosis of this disease due to its clinical similarity and histopathological
examination of chronic non-healing lesions in the early period is required.

Kronik Venöz Yetmezlikli Olguda Psödo-Kaposi Sarkomu: Olgu Sunumu

Abstract

Akroanjiodermatit, klinik ve histopatolojik olarak Kaposi sarkomuna benzeyen selim vasküler bir
dermatozdur. Psödo-Kaposi sarkomu olarakta bilinen bu hastalık nadir görülmekte olup, kaposi sarkom
ile karışabilmektedir. Olgumuz seksenbeş yaşında kadın hasta olup, her iki alt ekstremitenin distal
dorsalateral yüzeylerinde eritemli, yaygın variköz genişlemeler, retiküler damarlarda artış, deride incelme
ve ödem gibi bulgular tespit edildi. Klinik ve histopatolojik değerlendirme sonucunda olguya Psödo-
Kaposi sarkomu tanısı konuldu. Klinik benzerliği nedeniyle bu hastalığın tanısında biyopsinin önemli bir
yeri vardır ve erken dönemde kronik iyileşmeyen lezyonlardan histopatolojik inceleme yapılması şarttır.
