Abstract
Background Classic Kaposi's sarcoma (CKS) is not uncommon in Greece with a reported incidence of 0.20 per 100,000 per year. Methods Epidemiological, clinical and histological features of all CKS cases, diagnosed in‘A. Sygros’ hospital, Athens, Greece during the years 1989–1994, have been recorded and studied prospectively. Results During the five‐year period studied, 66 CKS patients have been diagnosed in our hospital. Incidence among dermatologic patients was 2.11 per 10,000 patients examined, representing 1.35% of total skin malignancies. Patients' age at diagnosis ranged from 53 to 94 years (mean 72±8.8). The male to female ratio was 2.47:1. A high proportion of the patients were born in Peloponnesos (42.42%) and were residing in Athens (51.51%) or in Peloponnesos (24.24%). Nodules and/or plaques were the most frequent type of lesion, most commonly located on the feet (43.93%) or the hands (28.78%). Accompanying edema was seen in 51.51% of the patients. There were 16 stage I patients (24.24%), 40 stage II (60.60%), 0 stage III and 10 stage IV (15.15%). Involvement of visceral organs was detected in seven patients (10.60%), while 10 had lymph node involvement (15.15%) and three, involvement of the underlying bones (4.54%). Second primary malignancy was diagnosed in 6 cases (9.09%), most often of the reticuloendothelial system (83.33%). Conclusions CKS in Greece exhibits some special characteristics, including older age of onset; lower male to female ratio; endemic clustering; disseminated skin disease at diagnosis, often accompanied by lymphedema; not unusual visceral or lymph node involvement and association with second malignancies. We suggest that CKS in Greece possibly represents a distinct endemic subtype of CKS.
