Bilateral Pulmonary Arteriovenous Malformations: Challenges in a Rare and Complex Case.

Pulmonary arteriovenous malformations (PAVMs) are abnormal vascular connections between the pulmonary arteries and pulmonary veins. Despite their relatively uncommon incidence, PAVMs should be considered in the differential diagnosis of children presenting with cyanosis due to the life-threatening complications posed by paradoxical emboli. The primary management approach involves eliminating the abnormal connections, either through surgical or endovascular methods.

Pure Erythroleukemia (Variant Acute Myeloid Leukemia-vAML-M6) with Deletion of Chromosome 20, Mainly Presenting as Late Erythroblasts, a Unique Case Report with Review of Literature.

Acute erythroleukemia is characterized by a predominant immature erythroid population and accounts for approximately 2-5 % of all cases of acute leukemia. Two subtypes are recognized based on the presence or absence of a significant myeloid component: erythroleukemia and pure erythroid leukemia. Erythroleukemia is predominantly a disease of adults, while pure erythroid leukemia can be seen in any age including children.
