    Notes: Summary We describe four lymph node based tumours in which numerous neoplastic cells and some mitotic figures were characterized by staining affinity for Lectin I of Ulex europaeus (UEA-I). The patients had no vascular or epithelial tumours and presented symptoms suggestive of a systemic lymphoproliferative disease. Histologically, the tumours were composed of large, cohesive, cells which were mainly located in the paracortex. UEA-I reactivity was more evident in the Golgi area and was present in large mononucleated cells often arranged to delimit vascular-like spaces. The neoplastic cells were weakly muramidase-positive in one case, and were ANAE+/AP + in two other cases. Large dots of UEA-I reactivity were detected in S-100+/muramidase-negative Langerhans-like cells present in one case of Letterer-Siwe disease. UEA-I staining was consistently negative in 20 cases of B cell- or T cell lymphoma and in 9 other cases of histiocytic lymphoma. It is suggested that UEA-I+ tumours of the lymph nodes are part of a distinct subset of histiocytic malignancies whose neoplastic cells present some morphological and phenotypic properties normally associated with endothelial cells.

    Notes: Abstract An increased incidence of different malignancies associated to chroniclymphocytic leukemia (CLL) has been reported. The association of CLL and acuteleukemia is a rare event described in 〈1% of CLL, the type of acuteleukemia being either from the lymphoid or more often from the myeloidlineage. The coexistence of acute myeloid leukemia (AML) and CLL in the samepatient has been occasionally reported. Most of these cases have beenassociated with the administration of chemotherapy or radioterapy for CLL,suggesting that the former may be a secondary leukemia. On the other hand, CLLcould precede, but could also be diagnosed at the same, or delayed time asAML, suggesting the presence of other leukemogenic factors. We describe theexceptional development of AML and lung cancer in a patient with previouslydiagnosed CLL in minimal residual disease status after fludarabine treatmentfollowed by autologous peripheral blood stem-cell transplantation.
