[Thrombotic thrombocytopenic purpura: report of seven cases].

From May 1999 to January 2002 we observed 7 patients (4 females and 3 males, median age 55 years, range 31-81 years) with thrombotic thrombocytopenic purpura (TTP). Six patients has been previously undiagnosed and 1 patient was at second relapse. Trigger factors of TTP were identified in 6 patients: ticlopidine treatment (2 patients); an acute cutaneous infection episode immediately before the features of TTP (1 patient); presence of devices: orthodontic (1 patient) and intrauterine contraceptive (1 patient), Mycoplasma urealyticum vaginal infection (1 patient).

Primary pancreatic lymphoma. Report of five cases.

Primary pancreatic lymphoma (PPL) is a very rare disease. We report five cases of PPL (4 men and 1 woman, mean age 65 years) diagnosed and treated at our Institution from 1987 to 1997. None of these patients had evidence of extrapancreatic disease and they were categorized as PPL involving pancreas only (stage IE, 3 patients) or pancreas and peripancreatic lymph nodes (stage IIE, 2 patients).

Safety and efficacy of enoxaparin treatment in venous thromboembolic disease during acute leukemia.

Background: Venous thromboembolism (VTE) is a quite common complication in acute leukemia, although its real incidence is unknown. The best treatment of this complication is still a matter of debate due to the very high risk of hemorrhage in this group of patients.

Patients And Methods: From December 2000 to December 2002 four Caucasian patients with acute leukemia developed VTE complications.

Advanced waldenström's macroglobulinemia: a case of possible cure after systemic chemotherapy, splenic radiation and splenectomy.

A 41-year-old man with advanced Waldenström's macroglobulinemia (WM) associated with the hyperviscosity syndrome, massive splenomegaly and with IgM concentration of 10 g/dl, was treated in January 1984 with plasmapheresis, systemic chemotherapy (M2 protocol) and splenic radiotherapy. He rapidly improved and was discharged 1 month later. Fourteen months later he underwent splenectomy since a mild splenomegaly persisted though the normalization of bone marrow, peripheral blood and electrophoresis with an IgM concentration of 140 mg/dl.
