- BACKGROUND
The purpose of this study was to investigate the prognostic significance of the Epstein-Barr virus (EBV) infected non-neoplastic lymphocytes in patients with Hodgkin lymphoma (HL).
METHODS
Seventy-seven cases of HL were evaluated by immunohistochemical analysis and EBV-encoded RNA in situ hybridization. The cases were divided into three groups according to the EBV status. EBV was negative in 48 cases (group 1), EBV was located in the Hodgkin/Reed-Sternberg (HRS) cells, but not in the non-neoplastic lymphocytes in 20 cases (26%) (group 2) and EBV was located in both the HRS cells and the non-neoplastic lymphocytes in 9 cases (12%) (group 3).
RESULTS
The groups differed with respect to the age distribution, the clinical presentation and the prognosis.
The median ages were 30 (group 1), 47.5 (group 2) and 23 years (group 3) (p = 0.011). B symptoms (p = 0.007) and the histologic subtype of mixed cellularity classical HL (p = 0.001) were more common in the EBV-positive patients than in their EBV-negative counterparts. Two patients from group 3 had associated chronic EBV infection syndrome. The five-year survival rate was 97.56% in group 1, 75.76% in group 2 and 100% in group 3 (p = 0.0178).
CONCLUSIONS
HL with EBV located in both the HRS cells and the non-neoplastic lymphocytes is a distinct prognostic subgroup that has better survival than the HL with EBV located in only the HRS cells.

Abstract
PDF
- Herein, we describe cases of pulmonary acute graft-versus-host disease (aGVHD) in two patients occurring after allogeneic hematopoietic stem cell transplantation (HSCT) due to precursor B-cell acute lymphoblastic leukemia in a 6-year-old patient and in acute myeloid leukemia in a 14-year-old boy. In both cases, chest CT revealed confluent ground-glass attenuation along the bronchovascular bundles, as well as some bronchial dilatation. Microscopically, in both cases we noted a characteristic bronchiolocentric pattern and bronchiolar epithelial changes, which included denudation of the bronchiolar epithelium, regenerating atypical cells, and wall thickening with subepithelial or transmural fibroblast proliferation, along with some lymphocytic infiltration. One patient died on day 86 after allogeneic HSCT due to sudden acute respiratory distress syndrome, and the other patient currently remains alive without active aGVHD. The authors' experiences in these two cases demonstrate that intense awareness of the pathologic findings of GVHD is mandatory after allogeneic HSCT.
