title: [Stewart-Treves syndrome].
abstract: Lymphangiosarcoma is an uncommon vascular tumor that usually develops in longstanding lymphedema. We gathered the cases of lymphangioma observed in a hospital and attempted to analyze their characteristics: age, sex, localization, treatment and follow-up data. We studied five cases: three cases of Stewart-Treves syndrome after mastectomy and radiotherapy and two cases that developed in patients with late-onset congenital lymphedema. There were four women and one man. Radical surgery was performed in four patients. The techniques employed were: above-knee amputation (one patient), hip disarticulation (one patient), scapulo-humeral disarticulation (two patients) and gemcitabine and radiotherapy in one patient with metastatic disease at diagnosis. Three patients died in the first 14 months of follow-up, while two are disease free after 46 and 86 months respectively. This study confirms the poor prognosis of patients with Steward-Treves syndrome.
