title: Large granular lymphocyte proliferative disease: 21 Belgian cases and review of the literature.
abstract: We report the findings in 21 Belgian patients (12 males and 9 females, median age 61 years) with LGLPD. Symptoms at presentation included infection (n = 9), weight loss (n = 5), asthenia (n = 9), pruritus (n = 2) and arthralgia (n = 7). Four patients were asymptomatic. The main clinical findings were hepatomegaly (n = 5), splenomegaly (n = 8), lymph node enlargement (n = 3) and arthritis (n = 5). All patients had an increased LGL count associated with anemia (n = 12), neutropenia (n = 17), often less than 0.5.10(9)/L (n = 10) and thrombocytopenia (n = 6). Three patterns of lymphocyte surface markers were observed: CD3+CD4-8+ (14 patients), CD3+CD4-8+ (5 patients) and CD3+CD4+8- (1 patient). An abnormal karyotype was found in 2 patients. T-cell receptor gene was rearranged in all cases tested (9/9).
