Pyothorax-associated Lymphoma

Pyothorax-associated lymphoma.

In Japan, EBV positive rate in immunocompetent patients with nodal lymphomas is less than 10% in B-cell and 20-50% in T cell lymphoma. Among extranodal lymphomas, EBV positive rate is higher in pyothorax-associated lymphoma (PAL), nasal NK/T-cell lymphoma, and adrenal lymphoma. PAL is non-Hodgkin's lymphoma that develops from chronic pyothorax resulted from artificial pneumothorax for the treat...

Extrapleural pneumonectomy for pyothorax-associated lymphoma.

Pyothorax-associated lymphoma (PAL) is a non-Hodgkin's lymphoma that occurs in the pleural cavity of patients with a long-standing history of pyothorax. Here, we report a left pleuropneumonectomy performed for PAL in a 76-year-old male patient with a 60-year history of pyothorax due to tuberculosis.

Lymphoma associated with Epstein-Barr virus-positive pyothorax.

[Usefulness of gallium-67 scintigraphy in diagnosing pyothorax-associated lymphoma].

Two cases of pyothorax-associated malignant lymphoma were reported. The presence of chronic tuberculous pyothorax after thoracoplasty and the development of non-Hodgkin's lymphoma on the chest wall are closely related. Both patients had suffered from tuberculous pyothorax for more than thirty years, and developed new painful chest wall tumors. CT and MRI delineated both malignant lymphoma and p...

Expression profile of human herpesvirus 8 (HHV-8) in pyothorax associated lymphoma and in effusion lymphoma.

AIMS Pyothorax associated lymphoma (PAL) occurs in a clinical setting of longstanding pyothorax or chronic inflammation of the pleura. Like primary effusion lymphoma, it has an association with Epstein-Barr virus (EBV), and is confined to the pleural cavity, but has differing morphological and phenotypic features. Human herpesvirus 8 (HHV-8) has been consistently reported in primary effusion ly...
