The authors describe a 13-month-old girl who presented with progressively worsening anasarca edema that developed over the last three weeks along with increasing fatigue. Over the last several months she was consuming progressively increasing amounts of fresh cow's milk. Laboratory examinations on admission showed severe microcytic and hypochromic anemia (hemoglobin 3.8 g/dl) and hypoferritenemia indicative of iron deficiency, while urinalyses showed no proteinuria. The child was transfused with 13ml/kg packed red blood cells and approximately 2g/kg intravenous albumin. On the second and fourth hospital days, she received 100 mg of iron sucrose intravenously that she tolerated well. Eight months after the described events, she is healthy with normal hemoglobin for age, while she has no laboratory evidence of cow's milk protein allergy. Pediatricians should be aware of the association of severe iron deficiency anemia (IDA) and anasarca edema, and should screen infants in their practice for anemia at the age of 12 months or sooner, if risk factors are present.

Objectives: To report a case of intravascular lymphoma (IVL) in a Caucasian patient who presented with anasarca as his sole clinical sign. Material and Methods: A man presented with anasarca-type oedema and fatigue. After excluding heart failure, hepatic cirrhosis, nephrotic syndrome, hypothyroidism, AL-amyloidosis and adverse drug reaction which can all cause oedema, we turned our attention to capillary permeability disorders. Results: Closer review of the bone marrow aspirate demonstrated haemophagocytic histiocytosis, while core, renal and duodenal biopsies showed a B-cell IVL. Conclusion: The differential diagnosis of anasarca, a relatively common clinical sign, should include IVL although the diagnosis may still be challenging.

Intravascular lymphoma (IVL) is a rare extra nodal subtype (usually of B-cell origin) presenting with infiltration of large neoplastic lymphocytes into lumina of blood vessels, leading to vascular occlusion. The early diagnosis is very crucial, however it is usually diagnosed postmortem investigation in most of the cases. A 56-year-old female presented with elevated creatinine level, and anasarca-type edema that superimposed with hard, indurated, erythematous plaques extending to inguinal region, abdomen, anterior aspect of chest, and face. B-cell IVL was confirmed with skin biopsy. The patient had some degree of clinical improvement following chemotherapy. B-cell IVL presenting with anasarca edema was not previously reported in the literature. Even if its rarity, IVL should be considered in the differential diagnosis of renal failure with anasarca edema. [ABSTRACT FROM AUTHOR]
