Mediastinal lymph node amyloidosis in a patient with sarcoidosis.

Transbronchial needle aspiration in the diagnosis of mediastinal amyloidosis.

We read with interest the pulmonary puzzle by Khor et al on mediastinal lymph node amyloidosis diagnosed by direct real-time endobronchial ultrasound-guided (EBUS) transbronchial needle aspiration (TBNA). The development of EBUS-TBNA is improving the diagnostic yield of mediastinal lymphadenopathy. However, we offer some comments about the diagnostic approach used in the case described. First, ...

Massive amyloidosis of mediastinal lymph nodes in a patient with multiple myeloma.

Lung Sarcoidosis in Etanercept Treated Rheumatoid Arthritis Patient: A Case Report and Review of the Literature

We report a 55-year-old female with seropositive rheumatoid arthritis for 10 years who developed large mediastinal and hilar adenopathy while receiving etanercept therapy. Chest high resolution computed tomography (HRCT) showed mediastinal lymph nodes with size of 2.3 × 3.1 centimeters. Right paratracheal lymph node biopsy showed nonnecrotizing epithelioid granulomata. All infectious studies of...

Lung Cancer Associated with Sarcoidosis - A case report -

Sarcoidosis is a somewhat common pulmonary disease, but the concurrence of lung cancer and sarcoidosis in the same patient is very rare. Because sarcoidosis usually presents as mediastinal lymphadenopathies, this concurrence in a lung cancer patient detected radiologically is apt to be misunderstood to be mediastinal metastases, and it is thus considered to be an unresectable disease. We report...

Paraneoplastic Sarcoidosis in Multiple Myeloma

Sarcoidosis predominantly affects the lungs, intrathoracic lymph nodes, and eyes; it less frequently affects the musculoskeletal system. We herein report a case of paraneoplastic sarcoidosis in a patient presenting with multiple myeloma. The patient developed ocular sarcoidosis and showed an increased 18F-fluorodeoxyglucose uptake in the mediastinal lymph nodes and vertebral column. A lymph nod...
