Cutaneous B-cell lymphomas constitute approximately 20% of primary cutaneous lymphomas. Most histologic subtypes of nodal B-cell lymphomas also occur primarily in the skin. The recently described T-cell-rich B-cell lymphomas (TCRBCLs) manifest mainly in the lymph nodes. This article presents a case of TCRBCL arising primarily in the skin, the origin of which could be traced back 13 years. The patient is a 59-year-old man. Plaque-like and nodular skin infiltrates had first appeared in the left preauricular region. Repeated examinations never found any extracutaneous involvement. A skin biopsy and a retrospectively studied 10-year-old skin specimen showed identical histologic features. Immunohistochemistry identified the TCRBCL previously considered as cutaneous Hodgkin's disease or a diffuse centroblastic centrocytic non-Hodgkin's lymphoma. A clonal B-cell population was detected by polymerase chain reaction, showing a rearrangement of IgH gene. The case of this patient shows that primary cutaneous TCRBCLs, similarly to other B-cell lymphomas in the skin, may have a good prognosis, in contrast to their nodal counterparts.

The objectives of this study were to assess the prevalence of oral manifestations of HIV infection, the periodontal health status and the oral health behaviour of a group of 51 HIV infected adults. The design was a cross-sectional descriptive study which took place in a community dental clinic in south London dedicated to treatment of this group of patients. Data were collected through a self-administrated questionnaire, interview and clinical examination and results showed that 76.5 per cent had one or more oral manifestations of HIV infection. Intra-oral herpes, papilloma and non-Hodgkin's lymphoma were not identified. A very positive attitude towards oral hygiene was identified. Plaque levels were low. All individuals studied had some evidence of bleeding gums.

The aim of this study was to examine whether the severe prolonged deficiency in marrow clonogenic progenitor cells reported after autologous stem cell transplantation (ASCT) is associated with impairment of the primitive progenitor cell compartment. We performed Dexter-type marrow cultures and limiting dilution assays with CD34(+) cells from patients 1 year and/or later after autografting with peripheral blood stem cells for non-Hodgkin's lymphoma (NHL). Flow cytometric analysis was used to assess the CD38 antigen expression and apoptotic state (7-ADD(-)/annexin-V(+) cells) of the CD34(+) cell population. We found a dramatic decrease in both clonogenic progenitor cell production and frequency of long term culture-initiating cells (LTC-IC) in all the patients tested at 1 year, even in those displaying normal progenitor cell frequency. Surprisingly, the clonogenic capacity of each LTC-IC was not increased. Flow cytometric analysis of the CD34(+) cell population confirmed this quantitative defect, with a reduction in the CD38(dim/neg) cell population but no increase in apoptosis. This defect did not improve over time up to 4 years after transplantation. In addition, qualitative abnormalities were revealed, demonstrated by decreased CD34 antigen expression, together with impaired differentiating properties of LTC-IC toward erythroid lineage at 1 year. This study indicates that both quantitative and qualitative abnormalities of the primitive progenitor cell compartment are a constant feature up to 4 years after autologous stem cell transplantation.
