Flow cytometry analysis of T cell subsets in skin of patients with specific cutaneous manifestation of B non-Hodgkin lymphoma.

Cutaneous lesions may be the atypical initial manifestation of blood disorder. Monoclonal antibodies identify surface phenotype of lymphocytes present in specific cutaneous lesions. We studied cutaneous infiltrates with flow cytometry in 10 cases of non-Hodgkin lymphoma.

In vivo and in vitro HeNe laser effects on phagocyte functions.

The goal of this work was to evaluate the effect of helium-neon (HeNe) laser irradiation on immunocompetent cells. We used the in vivo skin window method and in vitro granulocyte function tests. The study of cellular migration showed a marked decrease in vitro and in vivo in a dose-independent manner.

[Breast and skin localization of non-Hodgkin's lymphoma. Description of a clinical case].

A clinical case of a patient suffering from non-Hodgkin lymphoma with breast localization and skin infiltration is reported. Skin lesion was the presenting feature: after diagnosis and chemotherapy the relapse of lymphoma was characterized by breast infiltration. These particular localizations are discussed in terms of their unfavourable prognostic significance in lymphoma.
