RESUMO

One hundred cases of colorectal cancer resected at the University Hospital of Caracas are presented, with emphasis in the Pathological Findings (Anatomical location and staging included). Age and sex distribution are comparable to data presented in other local series; in contrast, the proportion of rectal cancer is below expectations (only 5% of all cancer of the large intestine). The majority of cases are diagnosed in advanced stages (predominantly Dukes stages B and C).

RESUMO

The clinical-pathological spectrum of ampullary cancer in 18 patients studied at the Department of Gastroenterology (Hospital Oncológico Padre Machado) during the last decade (1980-88) is presented. Involvement of the extrahepatic bile ducts was due to cancer of the ampullary region. In all cases diagnosis was confirmed by pathology. The value of ERCP is presented and the need to set apart this tumors from carcinoma of the head of the pancreas is emphasized. None of the nine cases treated with radical resection (Whipple) had operative mortality, and although follow-up for all cases is not long enough, two patients are alive and free of disease, five years after surgery. The value of prosthesis and biliary drainage for palliation is commented upon. Emphasis is placed on the need of using the term ampullary cancer in its proper connotation. Criteria for differentiating periampullary tumors (specially cancer of the head of the pancreas) are presented.

RESUMO

Autoimmune chronic active hepatitis (ACAH) is an infrequent modality of chronic hepatitis (CH) with clinical and laboratory findings of an autoimmune disorder. Clinical and pathological findings of 7 cases are presented; all were females with ages between 7 and 24 years. Main symptoms and signs were weight loss, malaise, arthralgias, fever, menstrual disturbances, hepatosplenomegaly, jaundice ascites and esophageal varices. Aminotransferases were elevated in all cases, and bilirubin, alkaline phosphatase and gammaglobulins were found to be raised in six. Antinuclear antibodies were positive in 5 cases, smooth muscle antibodies in 3, and antimitochondrial antibodies were detected in one. Morphological changes were those of chronic active hepatitis with variable degrees of fibrosis. Plasma cells were conspicuous. All patients received steroid treatment (Prednisone). It is concluded that the diagnosis of ACAH can be based on clinical and immunological criteria provided other causes of CH such as viral hepatitis, are ruled out.

RESUMO

Se presentan los hallazgos clinicopatologicos de 4 pacientes con tumores hepaticos vinculados al uso de anticonceptivos orales. Dos corresponden a un adenoma hepatocelular con la particularidad de que uno de ellos, llego a tener dimensiones similares al caso de mayor tamano descrito en la literatura. Otro caso correspondio a un carcinoma hepatocelular posiblemente como resultado de la malignizacion de un adenoma y finalmente un caso tipico de hiperplasia nodular focal

RESUMO

The case of a patient with a small bowel leiomyosarcoma in whom a correct preoperative diagnosis was done due to important clues provided by computed tomography is presented. We present these findings, and suggest that this new exploratory method may be useful for the study of patients with small bowel intramural tumors, in whom other studies are often non-conclusive.

RESUMO

Se presenta el caso de una paciente con un leiomiosarcoma del intestino delgado, en la cual se logro un diagnostico preoperatorio correcto gracias a los datos aportados por la tomografia computada. Se analizan estos hallazgos y se sugiere que este nuevo metodo diagnostico puede ser muy util para el estudio de pacientes con tumores intramurales del intestino delgado en los cuales otros estudios usualmente no son concluyentes
