Invasive aspergillosis is a common form of fungal infection in patients with hematological malignancies. Because Aspergillus species have angioinvasive properties, they frequently disseminate from the lung to a variety of organs via hematogenous spread. Extra-pulmonary involvement occurs at an advanced stage of invasive aspergillosis, and represents an ominous sign. However, few reports have been published on extra-pulmonary involvement in cases of aspergillosis. Its clinical features have not been fully clarified. We experienced a patient who developed thyrotoxicosis and fatal airway obstruction caused by invasive aspergillosis of the thyroid. A 26-year-old man was admitted to our hospital for the treatment of non-Hodgkin's lymphoma. During myelosuppression following the chemotherapy, he developed cervical swelling and hyperthyroidism. We suspected lymphoma infiltration to the thyroid, and irradiated it with a total of 26 Gy. However, the cervical lesion enlarged rapidly, and he complained of wheezing and dyspnea. We underwent immediate tracheostomy to secure the airway, but he died. Autopsy findings were striking. Extensive necrosis with diffuse infiltration of Aspergillus hyphae was observed in the thyroid gland. Necrotic tissues of the thyroid protruded into the tracheal lumen, causing airway obstruction. This case demonstrated that invasive aspergillosis of the thyroid can lead to medical emergency.

Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency characterized by reduced levels of all major immunoglobuline classes and recurrent c infections. The risk of non-Hodgkin's lymphoma (NHL) among patients with CVID was found to be increased in different studies. Mucosa-associated lymphoid tissue (MALT) lymphomas are a recently recognized sub-set of low-grade B-cell NHL composed of marginal zone-related cells. MALT lymphomas appear in the lymphoid tissues as a result of chronic inflammatory or autoimmune stimulation. This study briefly reviews previously published cases and reports a patient suffering from CVID with a history of chronic diarrhea and recurrent sinopulmonary infections. Despite treatment with intravenous immunoglobulin, chronic cough and wheezing progressed. Open lung biopsy showed a MALT lymphoma. Although a rare complication, pulmonary low grade B-cell lymphoma is a diagnosis that must be kept in mind in CVID patients with chronic pulmonary symptoms unresponsive to conventional therapies.

Primary pulmonary lymphoma (PPL) is an uncommon type of non-Hodgkin's lymphoma. The majority of PPLs are of low-grade, mucosa-associated lymphoid tissue type. Primary pulmonary diffuse large B-cell lymphoma (DLBCL) is extremely rare, and prompt diagnosis may be challenging since its clinical symptoms and signs are nonspecific. Although the clinical features, diagnostic procedures, optimal management and prognostic factors of this disease have not yet been well defined, open thoracotomy and chest computed tomography (CT)-guided percutaneous biopsy are the preferred methods used in previous studies. In the present case report, the diagnosis and management of a patient with primary pulmonary DLBCL is reported. A 68-year-old patient was admitted to hospital in May 2013, with complaints of shortness of breath and intermittent wheezing and a cough associated with the production of small amounts of phlegm. Following admission, chest CT scans revealed a mass in the right middle lobe with ground-glass opacities at the lesion margins, as well as air bronchograms in the areas of consolidation. Bronchoscopy was performed and revealed an endobronchial lesion and partial stenosis in the distal end of the middle segment bronchus. Transbronchial needle aspiration (TBNA) of the right hilar lymph node, as well as endobronchial biopsy, was performed. The patient was diagnosed with primary pulmonary DLBCL by subsequent histopathological and immunohistochemical analysis of biopsy specimens collected via TBNA. Following the final diagnosis, standard treatment with CHOP chemotherapy resulted in significant clinical and radiological response and the patient remained in remission 8 months later. These results indicate that TBNA may be an effective method for the diagnosis of primary pulmonary DLBCL.

A 2-year-old patient with a history of non-Hodgkin's lymphoma (NHL) was presented to our hospital with the complaint of shortness of breath and wheezing. Posteroanterior chest radiograph revealed hyperlucency and hyperexpansion of the right hemithorax. We performed computed tomography (CT) because of a suspicion of foreign body aspiration. CT revealed right main bronchus occlusion by a hypodense lesion. Bronchoscopy revealed a mass lesion in the right main bronchus which was histopathologically diagnosed as NHL. Only a few cases of endobronchial recurrence of lymphoma have been reported in the current literature, but there is no reported case in a pediatric patient.
