[A clinicopathological study on panniculitic T-cell lymphoma].
OBJECTIVE
To analyse the pathomorphology and clinical behavior of panniculitic T-cell lymphoma (PTCL) and to study the classification and name of PTCL.


METHODS
Routine pathological and immunohistochemical methods were utilized to analyse 4 cases of PTCL.


RESULTS
All patients presented with 1 to 3 cm diameter subcutaneous nodules accompanied by high fever. The clinical course of these patients was distinctive and progressive. All patients died within 4-9 months. Histologically, the lesions were composed of medium sized atypical cells (CD45RO+) infiltrating between fat cells, large numbers of bean bag cells (CD68+) could be observed.


CONCLUSIONS
PTCL is a type of peripheral T-cell lymphoma which is highly malignant.
