Clinics and Pathology

Phenotype / cell stem origin Peripheral CD4+ T-cell lymphoma
Epidemiology The disease is rare
Clinics The patients present superficial lymph node involvement. The cervical areas are predominantly affected, whereas thoracic adenopathies and deep abdominal involvement occur unfrequently at presentation.
Pathology The disease cannot be separated from the broad category of peripheral T-cell lymphoma (PTL). PTL is characterized by a heterogeneous cellular composition with small and large cells with an inflammarory background. Lennert's lymphoma can be recognized by the presence of numerous epithelioid histiocytes usually grouped in small clusters. Lennert's lymphoma is not considered as a distinct clinicopathological entity.
Treatment The disease must be treated with multiagent chemotherapy and/or radiation therapy as for other PTL
Evolution The disease usually runs a relatively aggressive clinical course.
Prognosis Median survival of 16 to 32 months was reported in some studies


Note Clonal aberrations are reported in the vast majority of cases. Chromosome 3 is frequently involved: trisomy 3 ; 3q rearrangements (duplication of bands 3q22-24 or 3q22 breaks) are recurrent abnormalities ; A 6q- chromosome was also reported.
