RESUMO
Local hepatic tuberculosis without active pulmonary or miliary tuberculosis is an uncommon diagnosis. Even less common is the finding of a nodular form of local hepatic tuberculosis. There is a growing incidence of the disease related to human immunodeficiency virus. The authors report a case of pseudotumoral hepatic tuberculosis in a patient without AIDS, manifesting as prolonged fever, diagnosed previously as metastatic liver. Imaging studies of the liver and laparoscopic findings suggested metastatic disease. The correct diagnosis was made by histology of biopsies obtained in laparoscopy, which is an easy and cheap method, with less morbidity and mortality than surgical intervention. The case report illustrates the difficulty in reaching the correct diagnosis, most often confused with carcinoma of the liver, primary or metastatic. A greater awareness of this rare clinical entity may prevent needless surgical intervention since the majority of patients respond well to antituberculous chemotherapy.

UNLABELLED: Porphyria cutanea tarda (PCT) is caused by reduced activity of hepatic uroporphyrinogen decarboxylase. However extrinsic factors such as alcohol abuse and drug intake are required for the clinical manifestation of the disease. Hepatitis C virus antibodies have been detected in a high percentage of patients with PCT. Hepatitis C virus is probably the main pathogenetic factor of liver damage in patients with PCT. AIM: To study the association between hepatitis C virus and PCT in our patients with PCT. MATERIAL AND METHODS: We have investigated six patients diagnosed of PCT in order to detect the presence of hepatitis C virus and other possible causes of the disease. RESULTS: We have found that 66% of our patients had hepatitis C virus antibodies, 50% ethanol abuse, of which 2/3 presented hepatitis C virus antibodies, and one case of HIV.

Wegener's granulomatosis is a necrotizing granulomatous vasculitis often characterized by involvement of the upper respiratory tract, lungs and kidney, although any organic system can be affected. We present the case of a female patient with Wegener's granulomatosis diagnosed by biopsy of the kidney, and severe gastrointestinal bleeding with fatal course. Endoscopic findings of the colon and the histopathology of the biopsy are discussed.

We reviewed 46 cases of Crohn's disease diagnosed during the period between 1978-1988, with the intention to analyse the age, sex, presentation, evolution, complications and diagnosis. The majority of patients were women, with a mean age of 39. In the last years we have seen an increment in our number of cases. The mean time to diagnosis was about 3.5 years. The main symptoms were abdominal pain, diarrhoea and loss of weight. The complications was of 40% in colonic disease and 75% when the affection was in ileum and colon. During the evolution 4 patients died, 2 of them from their Crohn's disease. One patient had a colonic carcinoma. In 15% of the cases there was a previous appendectomy. The most frequent radiological findings were in the small intestine: lack of haustration and cobblestone appearance. In the colon: lack of haustration and ulceration. The most frequent endoscopical findings were ulcers and a cobblestone appearance.
