Unlabelled: Lung infiltration still causes differential diagnostic difficulties, which may delay the start of definitive treatment., Case Report: The examination of a 30-year-old man began due intermittent, remittent and permanent fever. Chest X-ray confirmed infiltration in the right upper lobe, which was accompanied by elevated CRP and physiological levels of procalcitonin. Most likely atypical pneumonia, tuberculosis, Wegener's granulomatosis or a malignant process was suspected. Throughout his examination infection could not be verified, repeated CT guided transthoracic needle biopsy suggested the possibility of a malignant process. Through surgical exploration the intraoperative histology was not informative; thus, the pneumonitis-remodelled right lung was removed due to the possibility of malignant transformation. Histological examination revealed lymphocyte rich classical Hodgkin lymphoma, which was found to be stage IV/B based on the 18FDG-PET/CT scan; therefore, eight cycles of ABVD (adriablastin, bleomycin, vinblastine, and dacarbazine) therapy was administered successfully. The patient is currently (for 30 months) in a complete metabolic remission., Conclusion: Primary pulmonary Hodgkin lymphoma is a rare disease entity (in this case it might be the original process), in which the diagnosis is often difficult. 18FDG-PET/CT may be a useful early diagnostic tool investigating fever of unknown origin.

Unlabelled: Hodgkin lymphoma shows a well-known geographic pattern, but temporal changes have been found recently as well., Patients and Methods: The Authors analyzed 439 Hodgkin lymphoma patients' clinicopathological and treatment data. Patients were treated at our department from 1980 until the end of 2008., Results: The first period contained 117 patients, the second 147 and third 115 Hodgkin lymphoma patients. The mean age of the patients was 40.1, 35.9 and 36.8 years in order. The male/female ratio: 1.42, 1.45, 1.04 in order. The incidence of mixed cellularity histological subtype is decreasing; nodular sclerosis shows an increasing tendency. The number of early stage patients (59.12%) is beyond the advanced stage (40%) in the last decade. The 10-year overall survival data were progressing 44.1%, 70.6% and 90.5% (survival prognosis) in the last decade., Conclusions: Changes can be explained by the altered nature of Hodgkin lymphoma, the changes in socioeconomic status and the development of diagnostic and therapy methods.

Unlabelled: Recovery have been achieved in the majority of Hodgkin-lymphoma patients. Unfortunately some of the patients refracter and about third of the patients relapsed after the first-line treatment., Aim and Methods: We investigated the frequency and treatment of refracter or relapsed Hodgkin lymphoma patients between 1996 and 2006., Results: We examined 76 women and 71 men, who had HL in this period. 141 patients (95,9%) had remission after first-line therapy. 6 women were primary refracter, 4 of them had high-dose therapy and autolog stem cell transplantation. They died in spite of the multiple treatment. 31 patients - 13 men and 18 women - had relapse (16 cases were in one year). 14 patients had high-dose therapy and autolog stem cell transplantation, 11 patients had only chemotherapy, 3 had only radiotherapy and 3 patients were treated by combined modality treatment. 6 of the relapsed patients were died, 5 because of the progression of lymphoma and one because of secunder myelodysplasia., Conclusions: Relapsed patients have a good prognosis, but refracter patients have long chance despite autolog or allogen hemopoietic stem cell transplantation. Searching for new therapeutical modalities for these patients is extremely important.
