Clinical features of giardiasis vary greatly between individuals and may range from asymptomatic infection to severe malab− sorption syndrome. Whereas individuals with various forms of hypogammaglobu− linemia may show more severe disease and damage to the intestinal villi, AIDS patients do not appear to be at increased risk of severe giardiasis [1]. We present a case of duodenal giardiasis in a...

A study of consecutive bone marrow aspirates from 365 patients without lymphoproliferative disorder, ten patients with chronic lymphocytic leukemia (CLL), and 25 patients with malignant lymphoma disclosed a clear separation of normal from abnormal lymphoid nodules (LN). Normal LN were found in 47% of patients and were classified into lymphoici follicles and Iymphoid infiltrates. A new entity, n...

Abnormalities of serum immunoglobulin levels are frequently associated with such haematological disorders as primary aregenerative anaemia, haemolytic anaemia, neutropenia, thrombocytopenia, and leukaemia (Good et al., 1962). Recently, Hermans et al. (1966) reported a group of patients with nodular intestinal lymphoid hyperplasia and hypoy-globulinaemia. We have now seen thrombocytopenia, immun...

Nodular lymphoid hyperplasia of the stomach is a rare lymphoproliferative disorder. Here, we report a 38-year-old man who presented with multiple submucosal tumors of the stomach. Histologically, the lesions were characterized by multiple discrete submucosal nodules of lymphoid cells. The infiltrates between the lymphoid follicles were composed mainly of medium-sized lymphoid cells with abundan...
