Hodgkin lymphoma with cutaneous involvement.
ABSTRACT We report a case of a 54-year-old previously healthy man with Hodgkin lymphoma who presented initially with a solitary cutaneous ulcer. Unlike non-Hodgkin lymphoma subtypes, skin involvement of Hodgkin lymphoma is extremely rare. Furthermore, the prognosis of Hodgkin lymphoma with skin infiltration is felt to be extremely poor. Contrary to other reports, this case demonstrates that a good response with standard therapy is possible.

ABSTRACT: We report a case of a 22-year-old previously healthy woman with Hodgkin's lymphoma who presented initially with multiple lymphadenopathy and later, with a solitary cutaneous ulcer. Unlike Non-Hodgkin's lymphoma subtypes, skin involvement of Hodgkin's lymphoma is extremely rare. The prognosis of Hodgkin's lymphoma with skin infiltration is felt to be extremely poor. Contrary to other reports, this case demonstrates that a good response with standard therapy is possible.Case Reports 11/2012; 2012. DOI:10.1136/bcr-2012-007599

ABSTRACT: About 15% of patients diagnosed with classical Hodgkin's lymphoma (cHL) are considered high risk with unfavorable prognosis. The biology of the disease bears a direct relationship to its clinical course. However, some aspects of the disease are still being debated. Related topics include origin of neoplastic cells as circulating precursor versus germinal center B cell, and disease metastasis via hematogenous routes and the effect of HL circulation on relapse potential and further spread of the disease. The terminally differentiated giant neoplastic Hodgkin Reed-Sternberg (HRS) cells (HRSC) have limited proliferation and lack mobility. Therefore, they are unable to penetrate epithelium. Thus, the clinical aggressiveness of HRSCs that disseminate via both lymphatic and hematogenous may be determined by their molecular composition. This review discusses in detail the historical perspectives on scientific and clinical evidences of precursors of circulating HL cells and the prognostic importance of these circulating cells for predicting outcome.Critical reviews in oncology/hematology 10/2013; 89(3).

ABSTRACT: Psoriasis is a chronic inflammatory disease with a prevalence of approximately 2-3% in the general population. The majority of diagnosed patients have plaque psoriasis, and about 20% have moderate-to-severe disease. Itolizumab, a new monoclonal antibody specific for the CD6 molecule mainly expressed on T lymphocytes, has demonstrated to inhibit in vitro ligand-induced proliferation and pro-inflammatory cytokine production. We assessed the immunological and histopathological effect of the antibody using clinical samples taken from 26 patients with moderate-to-severe psoriasis included in a clinical trial. The precursor frequency of lymphocytes activated with anti-CD2/CD3/CD28 beads, as well as the number of interferon (IFN)-γ-secreting T cells after stimulation, were measured at different time points of the study. Serum cytokine levels and anti-idiotypic antibody response to itolizumab were also evaluated. Additionally, lymphocyte infiltration and epidermis hyperplasia were studied in five patients. A significant reduction in T cell proliferation capacity and number of IFN-γ-producing T cells was found in treated patients. Serum levels of interleukin-6, tumor necrosis factor and IFN-γ showed an overall trend toward reduction. No anti-idiotypic antibody response was detected. A significant reduction in the epidermis hyperplasia was observed in analyzed patients. These results support the relevance of the CD6 molecule as a therapeutic target for the treatment of this disease.mAbs 03/2014; 6(3). DOI:10.4161/mabs.28376 · 4.73 Impact Factor
