Undiagnosed lung cancer complicated by intracavitary aspergillosis]

A 54-year-old man was treated with an antifungal agent (itraconazole) for post-tuberculous intracavitary aspergillosis. Though clinical and radiological findings indicated that the patient's symptoms had gone into remission, aspergillosis recurred 4 months after the cessation of antifungal chemotherapy, requiring that the patient undergo an operation. Intraoperative and pathological findings revealed a squamous cell carcinoma contiguous to the cavity containing the aspergilloma. Though a few cases of aspergilloma within cavitating pulmonary carcinomas have been reported in the literature, the case of lung cancer we report was thought to arise from preformed lung scars surrounding a post-tuberculous cavity that contained an aspergilloma. Although conclusive distinctions between neoplasms and fungal infections are difficult to make, careful observation of the radiographic features is necessary when treating patients with fungus ball-type aspergillosis.     

A case report of endobronchial semi-invasive aspergillosis

Pulmonary aspergillosis may be classified under three main categories. These are invasive pulmonary aspergillosis, allergic bronchopulmonary aspergillosis and aspergilloma. Sometimes more than one form of the disease may be present at the same time. Semi-invasive aspergillosis is different from aspergilloma in that there is local invasion of the lung tissue. We have observed a previously healthy 42 year old female with a solitary pulmonary nodule on her radiograms. A diagnosis of endobronchial semi-invasive aspergillosis was established in this patient. We aimed to present this case report with a review of the literature.     

Pleural Aspergillosis with Bronchopleurocutaneous Fistula and Costal Bone Destruction: A Case Report

A 65-year-old man who, when young, had had tuberculosis treated by therapeutic pneumothorax, consulted his family physician for a constitutional syndrome and dyspnea. At this time radiologic studies showed left pleural effusion with bilateral calcified plaques, an infiltrate in the upper left lobe, and a picture compatible with aspergilloma, all suggesting semi-invasive aspergillosis. The patient failed to show up for his followup visit, so no therapy could be started or further diagnostic tests ordered. One month later he was admitted to this hospital for a bronchopleural fistula (empyema necessitatis) with subsequent spontaneous hydropneumothorax and costal bone involvement. The patient underwent surgery because of his rapid worsening condition. Biopsy examination revealed a large pleural aspergilloma. Despite immediate antifungal therapy, the patient died. We believe this to be the first report of pleural Aspergillus with a bronchopleurocutaneous fistula and costal bone destruction.     

呼吸系统曲霉菌病重叠综合症的新进展

肺部曲霉菌病是少见病,但近年逐年增多,包括变应性支气管肺曲菌病(allergic bronchopulmonary aspergillosis,ABPA)、曲菌球(aspergilloma)、慢性坏死性肺曲菌病(chronic necrotizing aspergillosis,CNA)、侵袭性肺曲菌病(invasive pulmonary aspergillosis,IPA)及全身播散性曲菌病等5型.其中ABPA、曲菌球甚至IPA可合并变应性曲霉菌性鼻窦炎(allergic Aspergillus sinusitis,AAS),可能与基础病及其治疗等因素有关.本文就近期文献报告的呼吸系统曲霉菌病重叠综合症作一综述.     

Pleural perforation of an aspergilloma cavity occurring in a patient with interstitial lung disease

An aspergilloma is a fungus ball resulting from colonization of pre-existing pulmonary cavities, which usually represents a non-invasive form of aspergillosis. Spontaneous rupture of the cavity containing the fungi into the pleural space is an unusual complication that has been reported occasionally in patients with leukemia and invasive aspergillosis. We report on this unusual complication occurring in a patient with underlying interstitial lung disease, in whom the aspergilloma cavity abruptly ruptured into the pleural space with subsequent hydropneumothorax and pleural spillage of the fungi.     

Semi-invasive aspergillosis with involvement of the thoracic wall cured by itraconazole

Pulmonary aspergillosis invading the thoracic wall is rare and of sombre prognosis. We report the case of a 49-year old man who developed a pulmonary aspergilloma some time after lung resection and radiotherapy for bronchial adenocarcinoma. Surgical excision of the aspergilloma was followed by sternal, then costal aspergillosis. Conventional surgery and antifungal therapy failed, and the lesion stubbornly followed a chronic course until itraconazole therapy was instituted, resulting in a complete cure which still persists nearly 4 years after withdrawal of any chemotherapy.     

Place of surgery in pulmonary aspergillosis and other pulmonary mycotic infections

Surgery is part of the therapeutic strategy of aspergillosis and mucormycosis. The aspergilloma is defined as a rounded mass, developing in a cavity by the proliferation of spores of Aspergillus. The most common complication was haemoptysis reported in 50-95% of cases. The pleuropulmonary lesions predisposing are: tuberculosis, residual pleural space, emphysema and lung destroyed by fibrosis or radiotherapy or bronchiectasis. The indications for surgery depend on symptoms, respiratory function, the parenchyma and the type of aspergilloma (simple or complex). In a patient with an intrapulmonary aspergilloma, lung resection preceded by embolization is recommended based on respiratory function. For intrapleural aspergilloma, thoracoplasty is recommended according to the patient's general condition. The invasive pulmonary aspergillosis (IPA) is characterized by an invasion of lung tissue and blood vessels by hyphae in immunocompromised patients. The death rate of patients who have an API after treatment for leukemia or lymphoma was 30 to 40%, after bone marrow transplantation 60%, after solid organ transplantation from 50 to 60% and after any other cause of immunocompromising from 70 to 85%. The main cause of these deaths is massive hemoptysis. Surgery (lobectomy) is indicated for the prevention of hemoptysis when the mass is in contact with the pulmonary artery or one of its branches, and if it increases in size with the disappearance of border security between the mass and the vessel wall. The patient will be operated in an emergency before the white blood cells do not exceed the threshold of 1000 cells/μl. A persistent residual mass after antifungal treatment may justify a lung resection (lobectomy or wedge) before a new aggressive therapy. Mucormycosis affects patients following immunocompromising states--haematologic malignancy, diabetes mellitus, transplantation, burns and malnutrition. The treatment of pulmonary mucormycosis combines surgical and medical approach.     

Surgery for pulmonary aspergilloma and pleural aspergillosis

Pulmonary aspergilloma and pleural aspergillosis are a potentially lifethreatening disease resulting from the colonization of lung or pleural cavities by the ubiquitous fungus Aspergillus fumigatus. Twenty four patients with pulmonary aspergilloma and five with pleural aspergillosis underwent major thoracic procedures at our hospital between 1976 and 1986. Fourteen of the patients had haemoptysis, in 9 it was recurrent, and in 5 life-threatening. Tuberculosis, pneumonia, and sarcoidosis were the most common preexisting lung lesions. Surgical procedures included 7 pleuropneumonectomies, 18 lobectomies and 4 wedge resections. The postoperative mortality rate was approximately 7% (2 pat.). Based on the pathological examination 4 patients had unexpectedly a bronchial carcinoma in addition to the aspergilloma. Bronchopleural fistula with persistent air space was a serious complication only for patients after pleuropneumonectomy. 23 patients including those with complex aspergilloma and pleural infection had no postoperative complications; in none of the 27 operative survivors were there any recurrent symptoms over a follow-up between one and ten years. Good-risk patients with documented aspergilloma, even asymptomatic, should be resected, because of the danger of exsanginating haemorrhage. For patients with pleural aspergillosis only the aggressive resection can provide effective long term palliation.     

Pulmonary aspergilloma, diagnosis and treatment

Pulmonary aspergilloma is a saprophytic form of aspergillosis, and the diagnosis is usually based on radiological findings such as thickened cavitary wall and fungus ball, and on positive serum antibody. Up to 58% of the patients with aspergilloma in Japan have medical history of tuberculosis. Serum anti-Aspergillus antigen is almost always positive in aspergilloma patients but aspergillus antigen is usually negative. Massive hemoptysis can be a fatal complication of aspergilloma, and the most common complication was respiratory failure according to our study. Surgical resection is the only promising intervention to cure the aspergilloma, however, low pulmonary function does not allow operation. Antifungal treatment is chosen for those who are out of operation indication, but the efficacy of antifungal treatment against aspergilloma is controversial. Some patients with aspergilloma show progressive form, and we define such aspergillosis as CNPA, chronic necrotizing aspergillosis, although the original entity of CNPA by Binder et al. is different. We make a diagnosis of CNPA only if all the following entity meets, 1; progressive shadows in radiological findings regardless of the presence of aspergilloma, 2; have some symptoms such as cough, sputum, hemosputum, hemoptysis or fever, 3; proof of Aspergillus attribution by mycological or pathological examination, 4; positive systemic inflammatory reaction, 5; neglect of other etiology of pulmonary diseases. Since CNPA is usually progressive, patients with CNPA should be treated with antifungals.     

Huge aspergilloma developed within a zone of scleroderma-related pulmonary fibrosis

In pulmonary aspergilloma, Aspergillus colonizes and proliferates as a saprophyte in deterged cavities deprived of local defense. Although pulmonary tuberculosis constitutes the one well-know predisposing factor, other causes can create favorable conditions. We describe a first published case of a huge aspergilloma which developed within a zone of pulmonary fibrosis secondary to systemic scleroderma. The patient was a 58-year-old woman in poor general health who experienced repeated episodes of hemoptysis and dyspnea. Physical examination disclosed sclerodactyly, generalized cutaneous sclerosis and Raynaud's phenomenon. There was no clinical history of pulmonary tuberculosis or bronchectasis. Aspergillosis serology was positive. Broncho-alveolar liquid was positive for Aspergillus fumigatus at direct examination and after culture. Immunological assessment confirmed scleroderma. The chest computed tomography scan showed a huge oblong-shaped opacity in the upper left lobe which had developed within a zone of pulmonary fibrosis. Medical management was instituted. The clinical course was marked by repeating hemoptysis and the stability of pulmonary lesions after two years. Management of scleroderma-related pulmonary aspergiloma remains difficult and complicated. Prognosis depends on the course of both conditions, scleroderma and aspergillosis.     

A long-term survivor with pulmonary large-cell neuroendocrine carcinoma

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) has been characterized by highly aggressive behavior, with early spread to both regional lymph nodes and distant sites and a rapidly fatal course. In fact, no reports have described an advanced pulmonary LCNEC patient who has had long-term survival. A patient with large-sized pulmonary LCNEC, who is free of disease 11 years after surgery and postoperative chemotherapy, was reported.     

A case of non-invasive pulmonary aspergillosis that rapidly deteriorated]

The pulmonary diseases caused by the Aspergillus species include invasive forms, for example, invasive pulmonary aspergillosis, chronic necrotizing pulmonary aspergillosis, and non-invasive pulmonary aspergillosis. Though these forms are defined pathologically by the presence of the Aspergillus species that invades the lung tissue, they are used as clinical entities. We report a case of non-invasive pulmonary aspergillosis which, from the clinical data, appeared likely to be misdiagnosed as the chronic invasive form. A 45 year-old man received chemoradiotherapy for lung cancer as well as undergoing an left upper lobectomy. Two weeks after the surgery the patient developed a cough, high fever and chest pain. Chest radiography and chest computed tomography showed a rapidly enlarging cavity with an internal mass and infiltration in the left lower lung field. A transbronchial biopsy specimen of the cavity wall showed fungal hyphae. Bronchial washing culture grew Aspergillus fumigatus. Itraconazole and amphotericin B were administered, but the patient's condition did not improve. A left lower lobectomy was performed. The histologic findings showed that the fungal hyphae were only on the surface of the cavity wall, and were surrounded by necrosis and widespread inflammatory cell infiltration. No fungal invasion of the viable lung tissue was seen. The area of infiltration revealed an organizing pneumonia without Aspergillus or other organisms. Our final diagnosis was non-invasive pulmonary aspergillosis. There has been no recurrence of the lung cancer or of the pulmonary aspergillosis in the three years since surgery. It is reported that non-invasive pulmonary aspergillosis passes through a period so active that it seems to be the invasive form for its entire clinical course. To avoid confusion in diagnosis, establishment of a comprehensive clinical classification of pulmonary aspergillosis will be needed.     

Asymptomatic metalloptysis complicating lobectomy in pulmonary aspergilloma – An unusual complication

Recurrent haemoptysis in pulmonary aspergilloma is an indication for surgical resection of the cavity and removal of the fungus ball, in patients with a sufficient pulmonary function to allow surgery. Use of titanium surgical clips in such cardiothoracic surgical procedures may be the source of unusual complications. We report one such unusual complication of expectoration of a titanium surgical clip through a right lobectomy stump, the procedure having been performed six years previously for a symptomatic aspergilloma. We believe this to be first instance of metalloptysis in a case of pulmonary aspergilloma, following lobectomy.

Pulmonary aspergilloma--radiological observations

The radiological appearances of 49 cases of aspergilloma seen over a period of 6 years among 36,340 hospital admissions are described. All the 49 patients had pulmonary tuberculosis as underlying disease with 6 (12.2%) having bacteriologically active disease. One patient had concomitant allergic bronchopulmonary aspergillosis (ABPA). Upper zone distribution, large cavity size, moderately thick cavity wall and overlying pleural thickening were some of the prominent features observed. Two cases of multiple (3 each) and 4 of bilateral aspergilloma were seen. Of 57 aspergillomas 47 were round or oval, 7 oblong, 2 polypoidal and 1 lobulated. Positional movement was observed in 30 cases. Spontaneous lysis was seen in one case. Tomography and lordotic view were found to be very useful techniques when postero-anterior films were unrevealing. The radiologic diagnosis of aspergilloma was confirmed by demonstration of serum precipitins against aspergilli in 44 cases.     

Large cell neuroendocrine carcinoma of the ampulla of Vater

BACKGROUND: Neuroendocrine tumors of the ampulla of Vater are extremely rare, and few cases of large cell neuroendocrine carcinoma (LCNEC) of the ampulla have been reported. METHODS: A 48-year-old male with obstructive jaundice was admitted to our hospital. On examination the patient was found to have a periampullary growth and subsequently underwent the Whipple's procedure. RESULTS: Histopathological examination and immunohistochemistry revealed features of LCNEC of the ampulla of Vater. The patient developed multiple liver metastases 6 months after Whipple's procedure. CONCLUSION: LCNEC of the ampulla of Vater is rare and highly aggressive, with a dismal prognosis.     

Primary large cell neuroendocrine carcinoma in the common bile duct: First Asian case report

Large cell neuroendocrine carcinoma (LCNEC) in the biliary system is a poorly differentiated, high-grade neuroendocrine tumor. These tumors exhibit aggressive behavior and an increased tendency for early nodal and distant metastases. Herein, we report an unusual case of a pure primary LCNEC of the common bile duct (CBD). A 75-year-old female presented with nausea and jaundice. The patient underwent a CBD excision with lymph node dissection. Upon histological and immunohistochemical examination, the tumor exhibited pure large cell-type neuroendocrine features. Metastases were noted in two of the eight lymph nodes. The patient was administered adjuvant chemotherapy. The patient’s cancer recurred 7 mo after surgery, and the patient died from liver failure 5 mo after recurrence. The prognosis of LCNEC of CBD remains poor despite curative resection and adjuvant chemotherapy. The role of additional therapies, such as multimodal treatment including radiation therapy, must be further studied to improve the prognoses of patients.     

Role of surgery in the treatment of pulmonary aspergillosis

INTRODUCTION: This article reviews the different forms of pulmonary disease caused by aspergillus and discusses the possible surgical treatments. The most well known is the classic aspergilloma which develops as a fungal ball in the centre of a pre-existing pulmonary cavity. STATE OF KNOWLEDGE: One can distinguish simple (few symptoms, thin walled cavity without immediate complications) and complex forms (patient generally unwell, thick cavity, complications). In the complex form, surgical intervention must be considered as a last resort. In the simple form, surgery is relatively benign and prevents disease progression. Pleural aspergillosis can occur, usually following the surgical removal of a cavity either in the short or medium term. Given the loss of lung parenchyma thoracoplasty is often the only option. OUTLINES: Two different scenarios occur in acute invasive aspergillosis where surgery may be indicated: firstly, surgery can be considered in the event of haemoptysis related to vascular erosion; secondly, resection of mycotic sequestrations before intensification or resumption of therapy may prevent a relapse. Semi-invasive aspergillosis usually occurs in territories of post-radiation fibrosis: after a phase of invasion equivalent to a lobar pneumonia, a secondary cavity appears containing a small fungal ball. Thoracoplasty is often the only surgical option. Ulcerating tracheobronchial aspergillosis has been observed following (cardio-) pulmonary transplant and this may progress to a characteristic invasive aspergillosis. CONCLUSIONS: Finally, rare observations of parietal aspergillosis could be treated by surgical resection and associated with systemic antifungal therapy. Optimum management of these patients requires a multidisciplinary approach.
