Síndrome de Stewart-Treves / Stewat-Treves Syndrome

El linfangiosarcoma es un tumor vascular infrecuente que asienta habitualmente sobre linfedema de larga evolución. Hemos recogido los casos observados de linfangioma en un hospital intentando analizar sus características: la edad, el sexo, la ubicación, tratamiento y los datos de seguimiento. Hemos estudiado 5 casos: 3 casos de síndrome de Steward-Treves tras mastectomía y radioterapia, y 2 que asientan en pacientes afectados de linfedema congénito (forma tardía). Cuatro eran mujeres y 1 varón. Se realizó cirugía radical en 4 pacientes. Las técnicas empleadas fueron: amputación supragoneal: 1; desarticulación de cadera: 1; desarticulación escapulohumeral: 2, y 1 tratado con gemcitabina y radioterapia ante la existencia de enfermedad metastásica en el momento del diagnóstico. Dentro de los primeros 14 meses de seguimiento fallecieron 3 pacientes y 2 se encuentran libres de enfermedad pasados 46 y 86 meses, respectivamente. Este estudio confirma el mal pronóstico de estos pacientes (AU)

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 (AU)

Glucagonoma and pseudoglucagonoma syndrome.

CONTEXT: Glucagonoma syndrome may present either associated with a pancreatic neoplasm which secretes glucagon or as a pseudo-glucagonoma associated with other diseases. It is extremely infrequent but well-known with a current prevalence estimated at 1/20,000,000. DESIGN: A retrospective review of glucagonoma and pseudoglucagonoma cases observed between January 1998 and December 2003 in three hospitals. PATIENTS: Five cases: 3 with a demonstrable glucagon-secreting tumor and 2 cases without an associated neoplasm. MAIN OUTCOME MEASURES: Age, sex, initial diagnosis, associated symptoms, and pathology were analyzed as were procedures employed in diagnosis, imaging studies, laboratory data, surgery and follow-up. RESULTS: Hyperglycemia and elevated plasma glucagon levels were found in all cases. In 3 cases, hypo-aminoacidemia and a descrease in fatty acids were found. No changes of zinc levels were observed. Abdominal ultrasound studies were of no value except in evaluating pancreatitis. A CT-scan was conclusive when a pancreatic neoplasm existed and 3 patients were operated on a curative basis. DISCUSSION: Necrolytic migratory erythema was the key diagnosis in all cases. Surgery was intended to be curative. The follow-up was of 8, 37 and 57 months in the cases of true glucagonoma syndrome. CONCLUSIONS: A real prevalence of glucagonoma syndrome could be greater than currently estimated. In our series, it was 13.5/20,000,000. Pseudoglucagonoma syndrome remains a rarity.
