Atypical presentation of Kaposi's sarcoma in the external ear

Abstract

We presented a case of Kaposi’s sarcoma that occurred in the external ear of a 36-year-old Caucasian man. He was othervvise healthy without a history of any predisposing factors. He had a nodular lesion in the left ear, of three-month duration. The lesion was excised completely. Histologic and immunohistologic findings were consistent with a diagnosis of Kaposi’s sarcoma.Serologic analyses were negative for anti-HIV antibody and anti-cytomegalovirus IgM and IgG and blood count was normal. Differential count of leucocytes and immunoglobulin electrophoresis were normal. During a two-year follow-up, no recurrences, development of new lesions, or HIV seroconversion were detected. To our knowledge, this case is the first to report a solitary lesion of Kaposi’s sarcoma occurring in the helix of the ear in a healthy young patient.

Abstract

Bu makalede, 36 yaflındaki sağlıklı bir erkek hasta- da kulak kepçesinde saptanan Kaposi sarkomu su- nuldu. Hastanın sol kulağında üç aydır var olan no- düler lezyon için predispozan herhangi bir faktör belirlenemedi. Lezyon tümüyle çıkarıldı. Histolojik ve immünhistolojik bulgular Kaposi sarkomu ile uyumluydu. Serolojik analizlerde anti-HIV ile anti- sitomegalovirüs IgM ve IgG antikorları negatif bu- lundu. Kan sayımı normaldi. Lökosit altgruplarının sayımı ve immünglobulin elektroforezi normal so- nuçlar verdi. İki yıllık izlem dönemi içinde hastada lezyon nüksü, yeni lezyon geliflimi, ya da HIV sero- konversiyonu gözlenmedi. İlgili literatürlerin taran- masında, kulak kepçesinde Kaposi sarkomuna ait soliter lezyonun bildirildiği genç sağlıklı bir olguya r a s t l a m a d ı k
