Malignant pleural mesothelioma with scalp, cerebellar, and finger metastases: a rare case.

Malignant pleural mesothelioma (MPM) is a rare and asbestosis-associated tumor. MPM commonly invades locally, mostly in the lung, heart, pericardium, chest wall, and vertebrae. Distant metastasis of MPM is very rare. Here we report a patient with MPM who presented with multiple unusual distant metastases. The patient’s thorax tomography demonstrated right-sided, irregularly-thickened pleura with nodular masses and invasion of the chest wall into the subcutaneous area. The patient underwent biopsy for a subcutaneous mass in the right anterior chest wall. Pathologic examination revealed a malignant mesenchymal tumor. During follow-up, he suffered from a painful nodule on the scalp and nodules on the fingers, as well as weakness in his right arm. Cranial magnetic resonance imaging illustrated a 1 cm nodule in the left cerebellar hemisphere. Histopathologic examination of the biopsy from the nodule on the scalp revealed a typical mixed type of MPM, with calretinin, vimentin and creatine 5/6 positivity. Distant metastases can be seen in MPM and a biopsy of metastatic regions can yield the diagnosis.

Long-term survival following bronchotomy for polypoid bronchial carcinoid tumours

OBJECTIVE Typical bronchial carcinoids are very low grade neuroendocrine neoplasm of the tracheobronchial tree and have very good results in surgical treatment. Surgical treatment varies from bronchotomy-excision to major resective procedures. We presented our results of bronchotomy, simple excision and long-term follow-up. METHODS In Atatürk Centre for Chest Disease and Chest Surgery, 16 patients with bronchial carcinoid tumour underwent bronchotomy-excision over a 23-year-period. In all of the cases tumours were in polypoid type. Except these 16 cases 51 patients with bronchial carcinoids underwent operations in the same period. Presenting symptoms were haemoptysis, cough, recurrent pulmonary infection, dyspnea and chest pain. Rigid bronchoscopies were performed on all of the patients preoperatively for diagnosis of the tumour and to determine the surgical procedure and we performed control bronchoscopies on all of the patients in their follow-up period. RESULTS Patients were checked for periods ranging from 2 to 23 years both radiologically and bronchoscopically. We did not find any recurrences and death related to surgery and morbidity rate were minimal. CONCLUSION We think that bronchotomy and simple excision are effective and safe procedures for the treatment of bronchial carcinoid tumours with low morbidity in selected cases like polypoid type lesions and have as good a long-term survival rate as the other surgical treatment methods have.

Disseminated cryptococcosis in a human immunodeficiency virus-negative patient: a case report.

Cryptococcus neoformans is a widely distributed saprophytic fungus that may cause opportunistic infections in normal and immunocompromised individuals particularly in patients with HIV infection. Disseminated infection in HIV‐negative individuals is occasionally seen: a 57‐year‐old HIV‐negative Turkish female initially presented with enlarged mediastinal lymph nodes and a large pulmonary parenchymal nodule, eventually diagnosed with disseminated cryptococcosis and tuberculosis.

Surgical Management of Pulmonary Aspergilloma

Records of 59 patients (41 males and 18 females) who underwent 70 operations for pulmonary aspergilloma in a 23-year period were examined retrospectively. Sixty-three operations were for primary treatment of pulmonary aspergilloma, and 7 were for complications of surgery. Twenty-six postoperative complications occurred in 19 patients. Three lobectomies that resulted in bronchopleural fistula were managed by intercostal muscle-flap closure and partial thoracomyoplasty. Two patients died within the first week of surgery. Surgery is the treatment of choice for most patients with pulmonary aspergilloma. Selective bronchial artery embolization is helpful only in combating hemoptysis, and this has been considered a temporary measure in most reports. Thus, open thoracotomy and anatomical resection are recommended as early as possible after the diagnosis is established.

Endobronchial Lipomatous Hamartoma

Pulmonary hamartomas are the most common benign neoplasm of the lung, occurring in the parenchyma or sometimes within the bronchi. Reported is a case of a 64-year-old male patient with an endobronchial tumor. Sleeve left upper lobectomy was performed and histhopathological examination revealed multiple growths of endobronchial hamartomatous foci. This report demonstrates that endobronchial hamartomas may develop from multiple foci.

Tracheal adenoid cystic carcinoma masquerading asthma: A case report

BackgroundTracheal tumors are often misdiagnosed as asthma and are treated with inhaled steroids and bronchodilators without resolution.Case PresentationHere, a patient with tracheal adenoid cystic carcinoma who had been previously diagnosed with difficult asthma was reported. The possibility of the presence of localized airway obstruction was raised when the flow-volume curve suggesting fixed airway obstruction, was obtained.ConclusionThe presenting case report emphasizes the fact that not all wheezes are asthma. It is critical to bear in mind that if a patient does not respond to appropriate anti-asthma therapy, localized obstructions should be ruled out before establishing the diagnosis of asthma.

Hungry bone syndrome after parathyroidectomy caused by an ectopic parathyroid adenoma

Hungry bone syndrome (HBS), i.e., persistent hypocalcemia and hypophosphatemia as a result of extensive remineralization, is rarely encountered in children after parathyroid surgery. Herein, we report a 12-year-old girl who was diagnosed to have an ectopic parathyroid adenoma, and HBS was observed in the postsurgical follow-up. The diagnosis and the risk factors are discussed in the light of the literature.

Surgical treatment of tracheal hamartoma

Tracheal hamartoma is a rare tumor and difficult to diagnose. A case is presented in which tracheal hamartoma was misdiagnosed and treated for four years as asthma. The tumor was curatively excised via posterolateral thoracotomy.

Giant Bronchogenic Cyst Mimicking Tension Pneumothorax

An 18-month-old girl presented with high fever and vomiting. Pneumothorax and a cystic formation in the right hemithorax were found on a chest radiograph. The cyst measuring 10 × 10 × 8 cm was resected by a simple wedge resection. Histology revealed a complicated bronchogenic cyst with abscess formation.

18F-FDG uptake in focal organising pneumonia mimicking bronchial carcinoma

Organising pneumonia (OP) is not a well‐known cause of increased 18F‐FDG uptake, and the relationship of the increased 18F‐FDG uptake to clinical parameters has not been clearly identified. This study aims to assess the role of positron emission tomography–computed tomography (PET‐CT) for the diagnosis of focal organised pneumonia that may mimic malignity because of mass‐like lesions on the radiological images it causes.
