Clinics and Pathology

Disease

B cell non Hodgkin lymphoma (NHL)

Epidemiology

Clinics

The 3 patients had diffuse large B cell lymphoma (DLBCL); 2 of 2 patients were male patients, one presented with a history of follicular small cleaved cell lymphoma 15 yrs ago, when aged 47 yr. This patient died 6 mths later of progressive disease.
