Hairy cell leukemia typically presents with pancytopenia and often mimics aplastic anemia. Making an accurate diagnosis is crucial, as treatment with the purine analogues cladribine and pentostatin brings about durable complete remission in the majority of patients. Surface kappa and lambda flow cytometric analyses of peripheral blood or bone marrow are a powerful screening tool, although routi...

Myeloid sarcoma is a rare tumor consisting of myeloid blasts that involve anatomic sites outside the bone marrow. Fatal prognosis is inevitable in patients with extramedullary relapse after hematopoietic stem cell transplantation (HSCT), and no standard treatments are available yet. We report the first case of extramedullary relapse after HSCT treated with a combination of daunorubicin, cytarab...

Rebound disease following cessation of disease modifying treatment (DMT) has been reported in people with both relapsing and progressive multiple sclerosis (pwRMS, pwPMS) questioning strict separation between these two phenotypes. While licensed DMT is available for pwRMS to counter rebound disease, no such option exists for pwPMS. We report on a pwPMS who developed rebound disease, with 45 Gad...

We describe a 35-year-old woman who presented with proteinuria and microscopic haematuria. Blood tests revealed a low C3 complement level, with no evidence of cryoglobulin. Renal biopsy showed a Type 1 membranoproliferative glomerulonephritis (MPGN) with isolated C3 deposits on immunofluorescence study. Bone marrow aspirate, done for monocytopenia, was consistent with a diagnosis of hairy cell ...
