Tumor cells at different progressive stages and in the mixed cultures with or without Con A stimulation also varied in the sensitivity to lymphocyte adhesion and emperipolesis. Tumor adhesiveness anl emperipolesis of theymus lymphocytes and their PNA-, PNA+ subgroups were shown to be different significantly from splenic lymphocytes. Thymosin exhibited certain promotive effect on lymphocyte-tumor adhesion and emperipolesis.展开更多

It is a rare histiocytic disorder worldwide, less than 1000 reported cases. It is of unknown etiology and is characterized in its classical form by multiple adenomegalia, especially localized at cervical area, but also at mediastinal, axillary and inguinal areas. It is a benign condition, even if it is deforming, with spontaneously resolving evolution. We report a case of DRD disease in a 13-year-old girl, hospitalized in the Department of Pediatrics of the Yalgado Ouédraogo University Hospital Center in Ouagadougou, in March 2015. She was admitted for a voluminous bilateral painless cervical swelling, with no sign of local compression, having been operating for about a year. Biological tests showed signs of chronic inflammation;the imagery specified the benign character of these formations: adenomegalia. Confirmation of the diagnosis was made by pathological examination, describing the aspect of emperipolesis to histology and, immunohistochemistry, polytypic plasmacytosis and PS100 positive/CD1a histiocytosis negative. The treatment could not be properly carried out, in view of the early discharge, against medical advice from the patient. The evolution would have been marked, according to the parents, by a slight involution of swelling.展开更多
