Kaposi's sarcoma after repeated surgical procedures in an immunocompetent patient: the lymphatic hypothesis

A 63-year-old Swiss patient developed acquired nodules on his right palm after 3 localized surgeries, called 'needle fasciotomy', for Dupuytren's disease. Kaposi's sarcoma (KS) was diagnosed in a biopsy of a nodule. A positive immunolabeling and serology for human herpesvirus 8 has been found, but human immunodeficiency virus and hepatitis C identification remained negative. The nodules were limited to the surgically traumatized area. This first report of a nonimmunocompromised patient developing a KS after repeated surgeries in a unique peculiar localized area with a dense lymphatic network sustains the hypothesis that tissue alterations involving the lymphatic system could play a central role in the occurrence of KS.
