Non Malignant Lymphoproliferative Disorders in Children: A Case Series.

Lymphoproliferative disorders occurs due to uncontrolled proliferation of lymphocytes that causes lymphocytosis, lymphadenopathy, and involvement of extra nodal sites (bone marrow, liver and spleen) and occur primarily due to immune dysfunction. We describe series of cases with non malignant LPD encountered in our practice and their varied clinical presentation, difficulties in diagnosis, underlying etiology, treatment and outcome. Many of these disorders are self limiting, however some are associated with significant morbidity, hence treatment must be tailored based on the underlying immune dysfunction and aggressiveness of the clone.

Targeted Next Generation Sequencing (NGS) to Diagnose Hereditary Hemolytic Anemias.

Hereditary hemolytic anemias present a unique diagnostic challenge due to their wide phenotypic and genotypic spectrum. Accurate diagnosis is essential to ensure appropriate treatment. We report two cases, which presented as hemolytic anemias, but initial workup was inconclusive and they were finally diagnosed with the help of Next Generation Sequencing (Dehydrated Hereditary Stomatocytosis and Kӧln Hemoglobinopathy).

Primary pulmonary diffuse large B-cell non-Hodgkin's lymphoma in a child.

A 3-year-old girl presented with a history of intermittent fever of six months duration associated with respiratory symptoms consisting of recurrent cough, fever, wheeze and a suspected history of contact with tuberculosis (TB). Chest radiograph revealed pulmonary infiltrates mimicking miliary TB. She was started on anti-tuberculous treatment, but in view of clinical deterioration, a further work-up including a lung biopsy revealed non-Hodgkin's lymphoma (NHL).
