Endobronchial aspergilloma: A case report and literature review

Unravelling lung adenocarcinoma in an immunocompetent patient with endobronchial aspergilloma: A case report

Inhalation of Aspergillus spp. can cause a wide spectrum of lung diseases. Endobronchial aspergilloma is an uncommon clinical entity that occurs because of Aspergillus spp. overgrowth in the airway lumen. We present a 73-year-old gentleman with a rare dual pathology of endobronchial aspergilloma and endobronchial adenocarcinoma. He initially presented with prolonged cough, dyspnoea, and haemoptysis. Bronchoscopy revealed an obstructed right main bronchus by a necrotic mass whereby histological examination showed evidence of Aspergillus spp. infection. The lesion however persisted despite treatment with anti-fungal agents. Repeated bronchoscopy and biopsy eventually unravelled an underlying endobronchial adenocarcinoma. He received chemotherapy but ultimately passed away 3 months later.

[Difficult case of differential diagnosis of partial lung atelectasis. Case report]

In December 2018 the patient over 60 years old sought medical help with complaints of persistent cough. Based on computed tomography data there were identified the sings (symptoms) of right lung lower lobe atelectasis. To run this patient diagnostics there were performed 6 bronchoscopies narrowed down by bronchi checks up only and described the right lung central cancer picture. At the same time the biopsy taken during one of the bronchoscopies appeared non informative. Fine needle biopsy of mediastinal lymph nodes and bronchial wall was performed twice: at Tomsk Cancer Research Institute (it was suspected B-cell lymphoma based on biopsy examination) and at The Loginov Moscow Clinical Scientific Center (signs of inflammation based on biopsy examination). The video-assisted thoracoscopy with lymph node dissection of the right lung root was performed in January 2020. As a surgical material analysis result reactive adenopathy was determined. Therefore, during more than 1 year of diagnostic research the genesis of right lung lower lobe atelectasis was not established. The patient was directed to Central Tuberculosis Research Institute for diagnosis verification. Based on clinical and radiological picture Central Tuberculosis Research Institute colleagues suspected a foreign body in the intermediate bronchus. During an endoscopic examination it was revealed stenosis, biopsies were performed, but the foreign body could not be identified. In the pathomorphological laboratory of Central Tuberculosis Research Institute there were conducted histological examination of the material after endobronchial cryobiopsy and rigid needle biopsy. Both gave an unexpected result: invasive mycosis of the bronchial wall. As a conclusion the decision was taken to apply antimycotic therapy on an outpatient basis. As a result, clear clinical and radiological positive dynamics was obtained. In these favorable conditions for endoscopic examination, it was performed vitally essential cryoextraction of foreign body. The foreign body turned out to be a fragment of a spongy bone of a centimeter size. These actions have let to unlock the right lung lower lobe.

An Unusual Pulmonary Aspergillus Infection: Endobronchial Aspergilloma

Endobronchial aspergilloma (EBA) is an extremely rare presentation of pulmonary involvement of Aspergillus. It is a noninvasive form of pulmonary aspergillosis where the fungus overgrows and colonizes the bronchial lumen. The patient may present with chronic cough, dyspnea, hemoptysis, or wheezing. The diagnosis is usually incidental when bronchoscopy is performed to evaluate the cause of hemoptysis or radiological abnormalities. Here, we report a case of a middle-aged female who presented with hemoptysis and right middle lobe collapse and was subsequently diagnosed to have EBA on bronchoscopy with endobronchial biopsy. Although EBA is rare, it should be considered as a differential in the evaluation of endobronchial mass lesions.

Obstructive Pneumonia Associated with Endobronchial Aspergilloma: Successful Treatment with Interventional Bronchoscopy and Antifungals

Endobronchial aspergilloma is a rare disease. A 64-year-old man with severe diabetes mellitus developed a cough and fever and was referred to our hospital. He was diagnosed with obstructive pneumonia associated with endobronchial aspergilloma, underwent interventional bronchoscopy, and was treated with antifungals. While the optimal treatment has not been established, interventional bronchoscopy along with systemic antifungals may improve the outcome in such cases.

An Unusual and Rare Presentation of Pulmonary Aspergillosis: Endobronchial Aspergilloma

Aspergillosis is a wide spectrum of the disease process that is caused by the fungus Aspergillus. Endobronchial aspergilloma is a very rare type of aspergillosis which is not yet included in the classification of aspergillosis. Due to its rare nature and a limited number of cases, there are no current treatment guidelines. Here we present the case of a 57-year-old female with an endobronchial aspergilloma. The patient was started on intravenous voriconazole and subsequently discharged on oral voriconazole.

Endobronchial lipoma with tracheobronchial aspergillosis: A case report

INTRODUCTION

Benign neoplasm of the endobronchial tree is quite rare, while endobronchial lipoma is extremely rare. Tracheobronchial aspergillosis is a relatively uncommon but severe form of invasive aspergillosis involving the tracheobronchial tree.

PATIENT CONCERNS

A 54-year-old male presented to our hospital for investigation and treatment of a cough and hemoptysis.

DIAGNOSIS

The diagnosis was confirmed as endobronchial lipoma with tracheobronchial aspergillosis.

INTERVENTIONS

The patient received pneumonectomy and voriconazole treatment.

OUTCOMES

The patient's postoperative course was uneventful, and he was discharged 10 days after surgery. The patient had no evidence of the fungal infection and recurrence during 1 year of follow-up.

CONCLUSION

Endobronchial lipoma is a rare benign lung tumor, and this is the first report of endobronchial lipoma with tracheobronchial aspergillosis. In patients with suspected endobronchial lipoma, especially those who present with hemoptysis as the initial symptom, it is advisable to exclude coexistent aspergillosis.

A Case of Endobronchial Aspergilloma Coexisting With Lung Adenocarcinoma

Aspergillus species can cause a variety of lung diseases. Endobronchial aspergilloma is a rare clinical entity rarely encountered and often not included in the classification of Aspergillus lung diseases.  An 82-year-old woman presented to the outpatient setting with wheezing, shortness of breath, and productive cough. CT of the chest showed the presence of airway enlargement in a finger in glove pattern in the right upper lobe suggestive of allergic bronchopulmonary aspergillosis. Despite adequate treatment the abnormality persisted on repeat imaging. Bronchoscopy with biopsies eventually revealed the presence of hyphal elements suggestive of Aspergillus and poorly differentiated adenocarcinoma. Endobronchial aspergilloma is rare and not included in the classification of Aspergillus lung diseases. It is thought to result from airway colonization by Aspergillus species. Occasionally it can obscure an underlying lung carcinoma and thus delay the diagnosis. Diagnosis is made by pathological examination of biopsy specimens. Optimal treatment is not well established.

Fatal Hemoptysis Due to Endobronchial Aspergilloma in the Hyperinflated Native Lung after Single-Lung Transplantation for Lymphangioleiomyomatosis: A Case Report

Pulmonary lymphangioleiomyomatosis accounts for the majority of cadaveric lung transplantation cases. Post-transplantation management is continuingly necessary not only to prevent the progression of LAM but also to address complications. A woman with lymphangioleiomyomatosis underwent cadaveric lung transplantation. She developed post-operative native lung hyperinflation and hemoptysis with cavity shadow in the native lung on computed tomography. Isolated Aspergillus from her sputum and positive Aspergillus galactomannan antigen in the blood led to a diagnosis of aspergillosis. Despite the reduction of hemoptysis by antifungal medication, she developed fatal hemoptysis. An autopsy showed an Aspergillus fungal mass in the bronchus in the native lung whilst the lung graft was free from lymphangioleiomyomatosis lesions. Endobronchial aspergilloma was suggested to be a cause of hemoptysis. This fatal clinical course suggested that hemoptysis due to endobronchial aspergilloma in the native lung should have been considered native lung pneumonectomy as a further intervention.

Endobronchial aspergilloma-a comprehensive literature review with focus on diagnosis and treatment modalities

Endobronchial aspergilloma (EBA) is a rare manifestation of pulmonary infection with Aspergillus spp. Comprised of hyphae, mucus, and cellular debris, the massive fungus overgrowth can lead to obstructive pneumonitis in large airways, manifesting as cough, dyspnea, hemoptysis, or weight loss. The aim of this paper is to review the literature on endobronchial aspergilloma to further elucidate this disease entity and to classify it as a non-invasive form of pulmonary aspergillosis. A descriptive analysis was performed on articles on PubMed database that contained the key word "endobronchial aspergilloma." A total of 28 cases were obtained. Four articles were excluded as they were not available in the English format. Although EBA is extremely rare, it should be considered in the differential diagnosis of endobronchial masses in immunocompromised patients. There is a potential for the disease entity to progress to tracheobronchitis and fulminant respiratory failure. As such, early detection with bronchoscopy, biopsy, and culture is required to confirm pulmonary aspergillosis. Current treatment regimens remain to be optimized, though piecemeal resection of the mycetoma with bronchoscopic techniques with the addition of systemic antifungals and their combinations has been reported as efficacious.

The pathogenicity ofAspergillus fumigatus, drug resistance, and nanoparticle delivery

The genus Aspergillus includes fungal species that cause major health issues of significant economic importance. These microorganisms are also the culprit for production of carcinogenic aflatoxins in grain storages, contaminating crops, and economically straining the production process. Aspergillus fumigatus is a very important pathogenic species, being responsible for high human morbidity and mortality on a global basis. The prevalence of these infections in immunosuppressed individuals is on the rise, and physicians struggle with the diagnosis of these deadly pathogens. Several virulence determinants facilitate fungal invasion and evasion of the host immune response. Metabolic functions are also important for virulence and drug resistance, since they allow fungi to obtain nutrients for their own survival and growth. Following a positive diagnostic identification, mortality rates remain high due, in part, to emerging resistance to frequently used antifungal drugs. In this review, we discuss the role of the main virulence, drug target, and drug resistance determinants. We conclude with the review of new technologies being developed to treat aspergillosis. In particular, microsphere and nanoparticle delivery systems are discussed in the context of improving drug bioavailability. Aspergillus will likely continue to cause problematic infections in immunocompromised patients, so it is imperative to improve treatment options.
