Introducción: La tuberculosis peritoneal (tuberculosis abdominal) puede ser confundida con una neoplasia maligna. Objetivo: Describir características clínicas y demográficas de pacientes con tuberculosis abdominal que semeja cáncer de ovario avanzado, diagnosticados en un centro oncológico de referencia nacional. Métodos: Se describen las características clínicas y patológicas de nueve pacientes con tuberculosis abdominal que clínicamente semejaba cáncer de ovario avanzado. Resultados: La mediana de edad fue de 47 años, el estrato socioeconómico más común fue bajo (44 %). El dolor abdominal y la pérdida ponderal se presentaron en 77.7 %, ascitis en 55.5 %, prueba COMBE positiva en 22.2 % y ausencia de antecedente de tuberculosis pulmonar en 100 %. La elevación de CA-125 se reportó en 77.7 %, con > 500 U/mL en 57.1 %. La tomografía indicó carcinomatosis en 50 % y tumor pélvico y ascitis en 37.5 %. Todas las pacientes fueron sometidas a cirugía; 62.5 % fueron diagnosticadas mediante estudio patológico transoperatorio como enfermedad neoplásica. Conclusión: La tuberculosis es considerada como la gran imitadora, por ello se debe tener en mente el diagnóstico de tuberculosis abdominal ante un caso sospechoso, aun cuando la presentación clínica, estudios de imagen e, incluso, el examen transoperatorio sugieran cáncer de ovario.
Introduction: Peritoneal tuberculosis (abdominal tuberculosis) can be confused with a malignant neoplasm. Objective: To describe clinical and demographic characteristics of patients with abdominal tuberculosis mimicking advanced ovarian cancer, diagnosed in a national reference cancer center. Methods: Clinical and pathological characteristics of nine patients with abdominal tuberculosis that clinically resembled advanced ovarian cancer are described. Results: Median age was 47 years; the most common socioeconomic status was low (44%). Abdominal pain and weight loss occurred in 77.7%; ascites, in 55.5%; 22.2% had a positive COMBE test, and 100% had no history of pulmonary tuberculosis. CA-125 elevation was reported in 77.7%, with levels > 500 U/mL in 57.1%. Tomography reported carcinomatosis in 50% and pelvic tumor and ascites in 37.5%. All patients underwent surgery, where 62.5% were diagnosed by intraoperative pathology study as neoplastic disease. Conclusion: Tuberculosis is considered the great imitator, which is why abdominal tuberculosis diagnosis should be borne in mind when faced with a suspicious case, even when clinical presentation, imaging studies, and even intraoperative examination suggest ovarian cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
