Abstract
in English, Spanish

We present the case of a patient who consulted for cough, showing a mass in the lower lobe of the right lung on imaging studies. Bronchoscopy revealed an irregular, whitish endobronchial formation, from which whitish membranes were aspirated. Biopsies were taken from the aspirated material and sent for analysis Based on the cyto and histopathological study, pulmonary hydatid disease coexisting with a sarcoma was diagnosed. In our area, hydatid disease continues to be frequent and its pulmonary location is, together with the hepatic, the two most common forms of presentation. The usual complication is the rupture of the cyst with the eventual seeding and its infection. In this case, the coexistence of hydatid disease with a pulmonary sarcoma was revealed, a fact of which we only know of one report, more than fifty years ago. The publication is motivated by the extremely infrequent nature of this association, highlighting the importance of carrying out histopathological studies even when clinical and imaging suspicion points to hydatid disease.

Se presenta el caso de un paciente que consultó por tos, evidenciándose en los estudios de imagen una masa en el lóbulo inferior del pulmón derecho. En la broncoscopía se observó una formación endobronquial, blanquecina, irregular, de la que se aspiraron membranas blanquecinas; del material aspirado se tomaron biopsias que se enviaron para su análisis. Con el estudio cito e histopatológico se diagnosticó hidatidosis pulmonar coexistente con un sarcoma. En nuestra zona la hidatidosis continúa siendo frecuente y su localización pulmonar es, junto a la hepática, las dos formas de presentación más comunes. La complicación habitual es la rotura del quiste con la eventual siembra y la infección del mismo. En este caso se pone de manifiesto la coexistencia de hidatidosis con un sarcoma pulmonar, hecho del que solo conocemos un informe, reportado hace más de cincuenta años. Motiva la publicación lo extremadamente infrecuente de esta asociación, resaltando la importancia de efectuar estudios histopatológicos aun cuando la sospecha clínica y de las imágenes orienten a la hidatidosis.
