Non-Hodgkin's lymphoma very rarely involves the esophagus, occurring in less than 1% of patients with gastrointestinal lymphoma. A few cases of mucosa-associated lymphoid tissue (MALT) lymphoma of the esophagus have been reported in the English literature. To our knowledge, there has been no report of MALT lymphoma of the esophagus coexistent with bronchus-associated lymphoid tissue lymphoma (BALT) of the lung. This report details the radiological and clinical findings of this first concurrent case.

CT and MRI are utilized to differentiate between different types of masses and to determine the extent of lesions involving the lacrimal gland and the fossa. Although many diseases that affect the lacrimal gland and fossa are specifically diagnosed by imaging, it is frequently very difficult to differentiate each specific disease on the basis of image characteristics alone due to intrinsic similarities. In lacrimal gland epithelial tumors, benign pleomorphic adenomas are seen most commonly with a well defined benign appearance, and a malignant adenoid cystic carcinoma is seen with a typical invasive malignant appearance. However, a malignant myoepithelial carcinoma is seen with a benign looking appearance. Lymphomatous lesions of the lacrimal gland include a broad spectrum ranging from reactive hyperplasia to malignant lymphoma. These lesions can be very difficult to differentiate both radiologically and pathologically. Generally, lymphomas tend to occur in older patients. The developmental cystic lesions found in the lacrimal fossa such as dermoid and epidermoid cysts can be diagnosed when the cyst involves the superior temporal quadrant of the orbit and manifests as a non-enhancing cystic mass and, in case of a lipoma, it is diagnosed as a total fatty mass. However, masses of granulocytic sarcoma and xanthogranuloma, as well as vascular masses, such as a hemangiopericytoma, are difficult to diagnose correctly on the basis of preoperative imaging findings alone. A careful clinical evaluation and moreover, a pathologic verification, are needed. In this pictorial review, the various imaging spectrums of pathologic masses involving the lacrimal gland and fossa are presented, along with appropriate anatomy and pathology reviews.

Extranodal marginal zone lymphoma is a low-grade B cell lymphoma that presents with an indolent clinicopathologic nature. Although this tumor can occur in various sites, including the gastrointestinal tract and lungs, it develops and spreads extremely rarely along the trachea and central airway. We report a case of extranodal lymphoma of mucosa-associated lymphoid tissue with tracheobronchial involvement. An 83-year-old woman presented with a cough and dyspnea. Bronchoscopic evaluation confirmed diffuse, multiple nodular lesions in both the trachea and large bronchi, and she was diagnosed with an extranodal marginal zone lymphoma of the tracheobronchial tree. After systemic chemotherapy, she survived for more than 18 months.

5.Sonographic and CT Findings of Sialadenosis in a Child with Leukemia.
Korean Journal of Radiology 2012;13(5):634-636
Sialadenosis is characterized by asymptomatic bilateral enlargement of the parotid glands. It is uncommon, especially in children. Diagnosis and analysis of sialadenosis based on imaging modalities have been rarely reported. Here, we report a case of sialadenosis in a child with leukemia, in which the diagnosis was made based on sonography and CT findings.

PURPOSE: Primary pulmonary lymphoma(PPL) arising in the lung as the initial site is very rare. Authors experienced two cases of PPL and report the radiologic findings and clinical characteristics with a brief reviewof the literature. METHODS AND MATERIALS: Plain chest radiograph and enhanced axial CT scan of the chest were taken. We analyzed radiologic findings of the two cases and correlated with broncoscopic and pathologic findings. RESULTS: Plain chest radiograph showed a mass like consolidative lesion on RML without peripheral atelectasis. Chest CT scan revealed a mass like consolidation with airbronchogram and the absence of a hilar mass or thoracic adenopathy. Percutaneous needle aspiration and biopsy(PCNA and PCNB) of the RML mass confirmed B-cell lymphoma, in both cases. CONCLUSION: PPL must be included in the differential diagnosis of chronic alveolar consolidation such as bronchioloalveolar cell carcinoma.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of cutaneous lymphoma. There have been a few case reports describing the radiologic imaging findings of SPTCL. We report a case of SPTCL, rarely presented with a breast mass. Here, we review her clinical history and radiologic (mammography and ultrasound) findings.

A 39-year-old man infected with human immunodeficiency virus (HIV) was admitted to our hospital because of sudden onset of chest pain. Chest radiography revealed pneumothorax of the right lung. Computed tomographic scans disclosed a 5.8-cm-sized emphysematous bulla in the right middle lobe of the lung. Histologically, the wedge-resected lung showed medium to large atypical cells within the bullous cavity of the Pneumocystis jirovecii pneumonia, without solid mass formation. These atypical cells were confirmed to be large B-cell lymphoma, Epstein-Barr virus-positive and human herpesvirus 8-negative. Therefore, this case was not diagnosed as primary effusion lymphoma, but effusion-based lymphoma arising in an emphysematous cavity of an HIV-infected patient. This type of effusion-based lymphoma has never been reported, and, although rare, it should be noted in order to clinically diagnose this lymphoma.

Bronchus-associated lymphoid tissue (BALT) lymphoma is a rare disorder and it is a characteristic subgroup of low-grade B-cell extranodal non-Hodgkin's lymphoma that is classified as marginal zone lymphoma. We report here on a patient with rheumatoid arthritis who developed BALT lymphoma. She had no pulmonary symptoms and the pulmonary nodules were incidentally detected by routine chest radiography. Chest CT showed a 2.8cm sized ill-defined focal consolidation of homogenous attenuation in the posterobasal segment of the right lower lobe. The histological diagnosis from the wedge resection specimen revealed low grade B cell lymphoma of BALT. To the best of our knowledge, this case is the first to report BALT lymphoma that developed in a Korean patient with rheumatoid arthritis. BALT lymphoma should be included in the differential diagnosis of the pulmonary nodules in patients with rheumatoid arthritis.

BALT(bronchial associated lymphoid tissue) lymphomas are a distinct subgroup of low-grade B-cell extranodal non-Hodgkin's lymphoma, which are classified as a marginal-zone lymphomas. The majority of the patients are asymptomatic or their pulmonary lesions is often discovered incidentally on a routine chest radiograph. A 50-year-old man was admitted for an the evaluation of cough, dyspnea and fever. His chest CT showed ground glass appearance with interlobular septal thickening in both lower lobes, right middle lobe and left lingular division. He had been initially diagnosed with lipoid pneumonia and was kept under observation. However, his chest lesion showed continuous progression and a video-associated thoracoscopy was performed His pulmonary lesion was confirmed histologically to be a BALT(bronchial associated lymphoid tissue) lymphoma. We report a case of a BALT lymphoma, which was initially misdiagnosed as lipoid pneumonia.
