Hepatosplenic T-cell lymphoma (HSTCL) is a rare form of extranodal non-Hodgkin lymphoma derived from cytotoxic T-cells, usually manifesting by sinusoidal infiltration of spleen, liver and bone marrow. In 1997 World Health Organization classified malignant lymphomas and placed HSTCL among peripheral T-cell neoplasms. The course of the diseases is usually very agressive with a median survival time of 8 to 16 moths despite multiagent chemotherapy. We present a case of a 48-year-old male patient whose initial symptoms were fatigue, weight loss and night sweats, which were followed by splenomegaly and pancytopenia. After clinical examination we suspected him to have HSTCL which was proved pathohistologically upon splenectomy and it is the first case of this lymphoma diagnosed in "Merkur" Clinical Hospital. As a first line of lymphoma therapy we decided to apply FED course (fludarabine, cyclophosphamide, prednisone), being aware of the published poor results the standard CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisolone) yields. As far as we know, the results of this chemotherapy course in the therapy of this tumor have never been published. The patient underwent 6 courses of FED therapy, which he tolerated well and was in good clinical condition. Upon the completion of the 6th course of therapy he was diagnosed with lung anaplastic microcellular carcinoma and was treated with 3 course of PE therapy (cisplatin, etoposide).

A 63 year old woman with non-Hodgkin lymphoma presented with unilateral pleural effusion, which when aspirated revealed CD19 and CD20 positive malignant cells. Prior to this, the patient had received several lines of chemotherapy (CHOP, VAD, FED) with no effect on pleural effusion. Repeated percutaneous drainage procedures were unable to control the effusion either. Rituximab was therefore instilled in a dose escalating manner via repeated pleurocenteses. Fifty days after the application of rituximab, pleural effusion was still present but reduced in size. Flow cytometry and immunocytochemistry performed on the same day showed CD19 positive cells which were lacking CD20 epitope, which could be explained by either engagement or destruction of the CD20 epitope upon interaction with rituximab making the detection of the CD20 molecule impossible by routine flow cytometry. What is especially interesting is the fact that even 50 days after the application of rituximab intrapleurally no new CD20 positive cells could be found in the pleural effusion by immunochemistry or flow cytometry, opening an interesting issue concerning the length of rituximab's activity when applied locally. Although our patient had no adverse effects, further analysis of rituximab's activity and safety when applied intrapleurally is warranted.
