ABSTRACT
El cáncer de colon es una causa rara y mal conocida de fiebre de origen desconocido (FOD).Se estima que menos del 1 por ciento de todos los casos de FOD son secundarios a una neoplasia de oculta de colon. Los autores presentan 4 casos de FOD como primera manifestación de un cáncer oculto del colon, haciendo énfasis en sus peculiaridades diagnósticas y patogénicas. La fiebre recurrente, sin patrón definido, de breve duración, autolimitada, imprevisible en cuanto a su aparición, debería hacer sospechar la existencia de un cáncer de colon oculto. En ocasiones la bacteriemia por Escherichia coli es también primera manifestación de esta neoplasia (AU)

Fever of unknown origin (FUO) has been rarely associated with colonic cancer. In less than 1% of cases of FUO a colonic cancer is found as the main cause of fever. The authors reviewed 4 cases of colonic cancer whose first manifestation was FUO. Recurrent episodes of brief, self-limited fever, without a characteristic pattern, may be the first symptom of colonic cancer. On occassions, E. coli bacteremia may be the herald of an occult colonic malignancy.

In 14 patients with secondary odditis, a biopsy of the papilla was studied, in one case encountering moderate peri and intrafascicular fibrosis and in another, erosion of the papillary mucosa with impaction of biliary material. In 6 biopsies obtained from patients with perforated liver cysticerocosis, submucosal edema of the biliary tree was observed in only 3. On the basis of these studies an analysis is made of the different percentages published, which are highly variable, and results are compared to those reported in larger series. Papillary affectation in lithiasis was related to trauma produced by impaction or expulsion of calculi and the indications for realization of sphincteroplasty or biliodigestive derivation are listed, showing a tendency toward a progressively greater restriction of surgery. The absence of sphincter disease in hepatic cysticercosis perforated into the biliary tract is signalled, the only alterations being edema, which is reversible with treatment of cysticercosis.
