PERIPHERAL T-CELL LYMPHOMA WITH PULMONARY INVOLVEMENT
COMENTÁRIOS
According to the WHO classification, lymphomas are divided into T-cell non-Hodgkin's lymphomas, B-cell non-Hodgkin's lymphomas and Hodgkin's disease. The T-cell non-Hodgkin's lymphomas may be peripheral or central.
Peripheral T-cell lymphomas (PTCLs) are more common in oriental countries, accounting for 25% of all non-Hodgkin's lymphomas in Korea. They can be classified as:
Extranodal nasal T-cell lymphoma
T-cell lymphoma concomitant with enteropathy
Subcutaneous panniculitis-type T-cell lymphoma
Fungoid mycosis/Sezary syndrome
Anaplastic, cutaneous or disseminated large cell lymphoma
Hepatosplenic T-cell lymphoma
Angioimmunoblastic T-cell lymphoma
Nonspecific peripheral T-cell lymphoma
Most PTCL cases are aggressive, and the prognosis is poor. The case presented is that of a nonspecific peripheral T-cell lymphoma, with nodal abdominal involvement (palpable mass) and pulmonary alterations. Prognosis is poor, and five-year survival is low. Positron emission tomography is of great value in disease staging, treatment control, detection of recurrence, and restaging, especially when coupled with computed tomography.
