Necrosis pulmonar masiva por micosis / Massive pulmonary necrosis due to mycosis

Introducción: La aspergilosis es una infección micótica oportunista que se presenta fundamentalmente en pacientes inmunodeprimidos y su principal fuente de transmisión lo constituyen las esporas presentes en el aire de salones de operaciones y unidades de cuidados intensivos. Objetivo: Presentar un caso de una micosis pulmonar masiva por una variante angioinvasiva de Aspergillus. Caso clínico: Se presenta un paciente con aspergilosis pulmonar grave, diagnosticada después de la resección de un tumor mediastinal. Se describen las características de la primera intervención, la evolución postoperatoria que condujo a la segunda, se muestran las imágenes tomográficas, quirúrgicas, microbiológicas y anátomo-patológicas que permitieron definir el diagnóstico. Conclusiones: La posibilidad de una micosis pulmonar debe tenerse en cuenta, aun cuando sea una afección rara y de manejo difícil, en pacientes inmunodeprimidos, con condensación pulmonar rebelde al tratamiento(AU)

Introduction: Aspergillosis is an opportunistic fungal infection that occurs mainly in immunosuppressed patients and its main source of transmission is the spores present in the air of operating rooms and intensive care units. Objective: To present a case of a massive pulmonary mycosis due to an angioinvasive variant of Aspergillus. Clinical case: A patient with severe pulmonary aspergillosis, diagnosed after resection of a mediastinal tumor, is presented. The characteristics of the first intervention are described, the postoperative evolution that led to the second one, the tomographic, surgical, microbiological and anatomo-pathological images that allowed to define the diagnosis are shown. Conclusions: The possibility of a pulmonary mycosis should be taken into account, even when it is a rare and difficult-to-handle condition, in immunocompromised patients, with pulmonary condensation that is rebellious to treatment. Aspergillosis is an opportunistic fungal infection that occurs mainly in immunosuppressed patients and its main source of transmission is the spores present in the air of operating rooms and intensive care units(AU)

Complications of chronic necrotizing pulmonary aspergillosis: review of published case reports

ABSTRACT Chronic necrotizing pulmonary aspergillosis (CNPA), a form of chronic pulmonary aspergillosis (CPA), affects immunocompetent or mildly immunocompromised persons with underlying pulmonary disease. These conditions are associated with high morbidity and mortality and often require long-term antifungal treatment. The long-term prognosis for patients with CNPA and the potential complications of CNPA have not been well documented. The aim of this study was to review published papers that report cases of CNPA complications and to highlight risk factors for development of CNPA. The complications in conjunction associated with CNPA are as follows: pseudomembranous necrotizing tracheobronchial aspergillosis, ankylosing spondylarthritis, pulmonary silicosis, acute respiratory distress syndrome, pulmonary Mycobacterium avium complex (MAC) disease, superinfection with Mycobacterium tuberculosis, and and pneumothorax. The diagnosis of CNPA is still a challenge. Culture and histologic examinations of bronchoscopically identified tracheobronchial mucus plugs and necrotic material should be performed in all immunocompromised individuals, even when the radiographic findings are unchanged. Early detection of intraluminal growth of Aspergillus and prompt antifungal therapy may facilitate the management of these patients and prevent development of complications.
