ABSTRACT
El síndrome de Muir-Torre comprende la asociación de uno o más tumores de glándulas sebáceas, con una o más malignidades internas y antecedentes familiares de neoplasias. Presentamos el caso de un paciente masculino de 33 años, con antecedentes familiares de cáncer de colon, que consulta a nuestro servicio por lesión en cuero cabelludo de seis meses de evolución, con posterior diagnóstico histopatológico de adenoma sebáceo. Dentro de los exámenes complementarios se observan por colonoscopía, dos lesiones que correspondieron a adenocarcinomas de colon bien diferenciados. Con los antecedentes familiares, el examen clínico y la histopatología se efectúa el diagnóstico de síndrome de Muir-Torre.
Muir-Torre syndrome represents the association of one or more sebaceous tumors, with one or more visceral malignancies and a family history of cancer. We report the case of a 33-year-old man, with a family history of colon cancer, who presented with a scalp tumor. The histopathological diagnosis was sebaceous adenoma. Two lesions were found in the colonoscopy, which corresponded to colon adenocarcionomas. With a compatible personal and family history of cancer and the results of the histopathology, we diagnosed the patient as Muir-Torre syndrome.

ABSTRACT
We present a new case of hepatic sinusoidal dilatation associated to giant lymph node hyperplasia or Castleman's disease in a 23-year-old patient with xanthelasmas and history of celiac disease. He presented with weight loss, hepatomegaly, periorbital xanthomas, anemia, accelerated erythrosedimentation rate, hypoalbuminemia, hypergammaglobulinemia at the expense of immunoglobulin G (IgG), high titers of autoantibodies, and increase of serum alkaline phosphatase and gamma glutamyl transpeptidase activity. A liver biopsy showed sinusoidal dilatation. Fifteen months later, a computed axial tomography showed a retroperitoneal tumor that turned out to be a giant lymph node hyperplasia. After resection of the tumor all clinic and biochemical manifestations had faded, suggesting an association between xanthelasmas, Castleman's disease, sinusoidal dilatation, and celiac disease. A humoral factor produced by the lymph tumor of the patient may have been responsible for the immunologic alterations he presented.

The aim of this prospectively designed study is to analyse the prevalence of HBV and HCV infections in 115 chronic alcohol abusers, their relation to epidemiological variables, and their meaning in pathogenesis and severity of alcoholic liver injury. A prevalence of 13.9% anti-HBc and 20.0% anti-HCV reactivity (EIA II) were found, significantly higher that found in blood donors (3.75 and 0.65% respectively). It is striking our finding of 69.6% "sporadic" type of HCV infection. Histological diagnostic of chronic hepatitis was done in 3 cases, all of them reactive to anti-HCV, enhancing the ethiologic role of HCV in the so called "alcoholic chronic hepatitis". No differences in histological final diagnosis were found related to HBV and HCV markers reactivity, suggesting no clear influence of viral infections on the severity of liver damage in alcoholics in our series. Neither anti-HCV positivity ratio seemed have to influence on these results. Despite a high prevalence of HBV and HCV infection in chronic alcohol abusers, our finding suggest no clear role for them in histological damage.
