s : Pyothorax-associated lymphoma (PAL) is an EBV-associated lymphoma, which develops in the pleural cavity of immunocompetent patients with an over-20-year history of pyothorax. PAL tumor cells taken from a 72-year-old man revealed having mismatch repair (MMR) phenotype and expression of all Epstein-Barr virus latent genes except EBNA-3B. EBNA-3B gene in the derived cell line had frameshift mu...

Primary lymphoma of adrenal glands is rare, and non-B-cell lymphoma associated with pyothorax is also very rare. Here we report the first autopsy case of non-B-cell lymphoma in bilateral adrenal glands of a 79-year-old woman with pyothorax who had an aggressive clinical course. Immunohistochemically, tumor cells showed CD3+, CD45RO+, CD5-, CD7-, CD4-, CD8-, CD10-, CD20-, CD30-, CD79a-, CD138-, ...

We report a case of pyothorax caused by Nocardia (N.) otitidiscaviarum infection in a 69-year-old man with rheumatoid vasculitis, who was regularly treated with prednisolone in our hospital. Initially, the patient responded poorly to intravenous imipenem/cilastatin (IPM/CS), minocyclin (MINO), and oral trimethoprim-sulfamethoxazole (TMP-SMX), but later improved after treatment with levofloxacin...

Pleural sepsis in children is common in most developing countries. It may present as total pyothorax, pyopneumothorax, or localised thoracic empyema. In most cases, it follows an attack of bronchopneumonia, but other debilitating conditions such as measles, malnutrition, and sickle cell anaemia form part of the clinical syndrome. In a review of 60 cases of pleural sepsis in children aged betwee...

Our previous study suggested a close relationship between a preceding chronic tuberculous pyothorax and the development of non-Hodgkin's lymphoma (NHL) in the pleural cavity. To confirm this further, 37 cases were collected, their clinical and pathological findings summarized. The age at first admission for lymphoma of patients ranged from 46 to 81 (mean 63) years, the male to female ratio bein...

A high incidence of non-Hodgkin's lymphoma of the pleural cavity has developed in Japanese patients with long-standing pyothorax (38 years on average) resulting from artificial pneumothorax for the treatment of pulmonary tuberculosis or tuberculous pleuritis. Patients with pyothorax-associated lymphoma (PAL) have long been exposed to antituberculous drugs, antibiotics, bacterial or viral produc...

Background: Pyothorax in cats is routinely managed, at least initially, with thoracic tube placement associated systemic antimicrobial administration. Traditionally, large-bore trocar-type thoracostomy tubes have preferentially been used for the drainage of thick material from pleural space. In recent years, use small-bore wire-guided drains has increased both small animals and humans. Few stud...

A 34-year-old man was referred to our institution for treatment of pyothorax that had proven to be incurable with antibiotics. His symptom was acute left chest pain. Abnormal findings were absent in the laboratory data and an electrocardiogram. A chest radiograph showed a left pericardial shadow and pleural effusion (Picture A). Chest CT revealed a mass adjacent to the thickened pericardium wit...
