          Abstract

          Informamos el caso de un hombre inmunocompetente que consultó por cuadro de sangrado digestivo alto secundario a una úlcera esofágica de origen tuberculoso. El compromiso gastrointestinal por el Mycobacterium tuberculosis es raro aun en pacientes con altas prevalencias de enfermedad pulmonar y extrapulmonar; los sitios de mayor afectación son íleon terminal y el peritoneo, la enfermedad esofágica es exótica y generalmente es secundaria a la extensión proveniente de órganos vecinos infectados, como ganglios mediastinales y/o bronquios. La clínica, las imágenes endoscópicas y radiológicas de la enfermedad esofágica suele simular una neoplasia maligna. La quimioterapia antituberculosa es la base del tratamiento, rara vez se requiere manejo quirúrgico.

          Translated abstract

          We report the case of an immune-competent man with symptoms of upper gastrointestinal bleeding secondary to esophageal ulcers of tubercular origin. Gastrointestinal involvement from Mycobacterium tuberculosis is rare even in patients with numerous occurrences of pulmonary and extrapulmonary diseases. The most frequently affected sites are the terminal ileum and the peritoneum. Esophageal tuberculosis is exotic and is usually secondary to extension from neighboring infected organs such as the mediastinal nodes and/or the bronchi. Clinical, endoscopic and radiological pictures of the esophageal disease often mimic malignancy. Tuberculosis treatment is the mainstay of treatment, and surgery is rarely required.

            Esophageal tuberculosis: is it so rare? Report of 12 cases and review of the literature.

            Mycobacterial involvement of the esophagus is rare in both immunocompetent and immunocompromised hosts with advanced pulmonary tuberculosis, even in countries with high prevalence rates like India. Most of the reported cases of esophageal tuberculosis (ET) are secondary to tuberculosis elsewhere in the body, most commonly pulmonary tuberculosis. Very few cases of isolated or primary ET have been reported, and most of them have been from developing countries. The upsurge in reported cases of tuberculosis linked to the AIDS epidemic has increased the incidence of this infection in developed countries also. Our aim is to study tuberculosis as an etiological factor in the causation of dysphagia, the role of cytology and histopathology in establishing its diagnosis, and the outcome of antitubercular treatment in these patients. A hospital-based, retrospective study was performed. We reviewed records of all of the patients who underwent upper GI endoscopic examination for complaints of persistent dysphagia (>6 wk) in a tertiary care hospital in India between 1995 and 1999. Patients with abnormal endoscopic findings were subjected to endoscopic fine needle aspiration/brush cytology and biopsies. Those with pathological findings suggestive of tuberculosis were treated with antitubercular therapy. Tubercular involvement of the esophagus, confirmed by pathological examination, was found in 12 patients. They constituted 0.5% of all patients with persistent dysphagia, and 1.3% of all patients having abnormal esophagoscopic findings. Cytological examination provided a very useful diagnostic parameter in detection of these cases. Patients diagnosed as having ET responded well to antitubercular therapy. Tuberculosis as a causative factor for dysphagia should be considered in developing countries with high incidences of tuberculosis and in immunocompromised hosts. Detection of these cases by careful examination of cytological smears and biopsies and treatment with standard antitubercular therapy appear effective.

              [Esophageal tuberculosis: case report and review of the literature].

              The esophageal tuberculosis is the rarest form of this infection in the gastrointestinal tract, corresponding to 0.15% of the cases. This pathology is unusual even in countries with high prevalence of tuberculosis. Its clinical presentation could be easily confused with the one of esophageal carcinoma. The diagnosis is reached by demonstrating in a sample of the mucosa the presence of caseating granulomas or by finding the Mycobacterium tuberculosis in a sample of tissue. In the present case report 73-year-old male with dysphagia, weight loss and fever is presented. At the endoscopy an ulcerated lesion of 5 centimeters in the lower third of the esophagus that compromises 50% of the circumference is observed. In the chest x-ray there are bilateral lung infiltrates confirmed by the CT scan. A baciloscopy is done and the result is positive. At the histological analysis giant cells are found and there is evidence of tuberculous bacillus. The patient develops an intestinal obstruction secondary to chagasic megacolon. He presents a massive hemoptisis and die. The aim of this presentation is to comment a pathology rarely reported in the literature and enhance the importance of considering it according to the clinical context.
