Pancytopenia due to iron deficiency worsened by iron infusion: a case report

<p>Abstract</p> <p>Introduction</p> <p>Iron deficiency anemia is commonly associated with thrombocytosis, although thrombocytopenia has been reported in occasional patients with iron-deficiency anemia. Much less common is the development of thrombocytopenia following replenishment of iron stores.</p> <p>Case Presentation</p> <p>We present the unusual case of a 39 year old African American female Jehovah's Witness who presented with a 10 month history of menorrhagia and pancytopenia. Laboratory investigations confirmed a severe iron deficiency. Since blood transfusion was unacceptable to her, she was started on intravenous iron replacement therapy. This precipitated a sudden drop in both her platelet and white blood cell counts. Histopathological examination of the bone marrow revealed a hypercellular marrow with orderly trilineage hematopoiesis, iron deficiency anemia, granulocytic hyperplasia, and mild megakaryocytic hypoplasia. Both her white blood cell and platelet counts recovered uneventfully with continuing iron supplementation. The possible mechanism for this phenomenon is discussed in this report.</p> <p>Conclusion</p> <p>This case illustrates two rather uncommon associations of a very common problem. Severe iron deficiency anemia may be associated with pancytopenia and iron replacement may cause a transient decline in megakaryopoiesis and leukopoiesis. Severe iron deficiency should be added to the list of conditions leading to thrombocytopenia.</p

Two Different Renal Cell Carcinomas and Multiple Angiomyolipomas in a Patient with Tuberous Sclerosis

We report a case of tuberous sclerosis associated with two histologically different renal cell carcinomas (RCCs) and multiple angiomyolipomas (AMLs) in the same kidney. A 43-year-old female was admitted to our hospital with left flank pain and a huge palpable mass in the left flank area. Abdominal computed tomography revealed two concurrent RCCs and multiple AMLs in the left kidney. Because of the clinical suspicion of RCC, the patient underwent left radical nephrectomy. On gross examination, the total size of the resected left kidney was 30.5×17×8 cm. Microscopically, the upper pole tumor features were consistent with chromophobe RCC and the midpole tumor was a clear-cell RCC. The multifocal masses in the remaining remnant parenchyma were AMLs. Six months after surgery, the patient is healthy without signs of tumor recurrence

Chronic neutrophilic leukaemia and plasma cell-related neutrophilic leukaemoid reactions

Many cases reported as ‘chronic neutrophilic leukaemia’ have had an associated plasma cell neoplasm. Recent evidence suggests that the great majority of such cases represent a neutrophilic leukaemoid reaction to the underlying multiple myeloma or monoclonal gammopathy of undetermined significance. We have analysed all accessible reported cases to clarify the likely diagnosis and to ascertain whether toxic granulation, Döhle bodies and an increased neutrophil alkaline phosphatase score were useful in making a distinction between chronic neutrophilic leukaemia and a neutrophilic leukaemoid reaction. We established that all these changes occur in both conditions. Toxic granulation and Döhle bodies are more consistently present in leukaemoid reactions but also occur quite frequently in chronic neutrophilic leukaemia. The neutrophil alkaline phosphatase score is increased in both conditions and is of no value in making a distinction

Coexistence of chronic neutrophilic leukemia with multiple myeloma

A case report of simultaneous presentation of chronic neutrophilic leukemia and multiple myeloma (IgG kappa) in a 71-year-old male is described. The patient showed mature neutrophilic leukocytosis, hepatosplenomegaly, high neutrophil alkaline phosphatase score, hyperuricemia, neutrophils with toxic granulation and Dohle bodies, absence of Philadelphia chromosome and of the bcr-abl fusion gene. Moreover, a monoclonal IgG kappa paraproteinemia (36.93 g l(-1)) was detected. Bence-Jones proteinuria was 3.84 g l(-1). The bone marrow was grossly hypercellular with marked myeloid hyperplasia and aggregates of plasma cells. The patient died of severe bronchopneumonia after the transformation of chronic neutrophilic leukemia to acute myelomonocytic leukemia, 1.5 years following diagnosis

Clonality of acquired primary pure red cell aplasia: Effectiveness of antithymocyte globulin

Primary pure red cell aplasia (PRCA) was diagnosed in two male patients, 65 and 69 years old respectively. In both, surface markers of peripheral blood nuclear cells revealed the presence of TCRalphabeta+ phenotype. Clonality of T cells was confirmed by the polymerase chain reaction in both patients, in whom, prednisone at a dose of 1 mg/kg/day improved the anemia and lower doses caused its renewal, resulting in the reappearance of the patient's transfusion requirement. On the other hand, the anemia seems to have been treated permanently (second case) with horse antithymocyte globulin (ATG) (20 mg/kg/day 1 to 8 +) since his hemoglobin was about 15 g/dl at the time of writing. In the first patient, the hemoglobin level was 10.5 g/dl one month after the administration of ATG (15 mg/kg/ d 1 to 5 +), but unfortunately, the patient died because of a massive gastrointestinal bleeding on the fortieth day following this treatment. We, therefore, suggest that, patients with acquired primary PRCA should be screened to detect the presence of a T-cell clone and recommend that, treatment should start earlier with ATG, if the PRCA is due to a T-cell clonal disorder
