[Clinical analysis of 10 cases of true histiocytic lymphoma].
OBJECTIVE
To explore the clinical and pathological characteristics of true histiocytic lymphoma.


METHODS
The clinical and pathological data of 10 true histiocytic lymphoma patients admitted between 1986 and 1996 to our hospital was retrospectively reviewed.


RESULTS
True histiocytic lymphoma accounted for 0.6% of non-Hodgkin's lymphoma(NHL) admitted in this period to our hospital. Enzymes associated with true histiocytic lymphoma were detected in all the 10 cases. The tumor cells were excluded from T/B lymphoid origin in 6 cases by immunohistochemistry. Eight cases received chemotherapy + irradiation +/- excision of primary lesion, 1 simply received irradiation and 1 received bone marrow transplantation. The response rate was 100%, with a 1, 3 and 5 year survival rate of 100%, 90% and 70%, respectively. The expected 10 year disease free survival rate is 40%.


CONCLUSIONS
True histiocytic lymphoma is a rare subset of NHL. Those originated from lymph node are sensitive to chemotherapy and irradiation with a favorable prognosis.
