The translocation (8;21)(q22;q22) is frequently associated with M2 subtype of AML. The authors herein present a case of AML-M2 in a nine-year-old boy without hepatosplenomegaly, lymphadenopathy or any bleeding diathesis. Bone marrow examination revealed high number of eosinophilic precursors (60%) among the total nucleated bone marrow cells. Cytogenetic study with G- banding method showed 46, XY, t (8;21)(q22;q22). The morphological abnormalities in eosinophils observed in AML suggested that eosinophils may be a part of leukemic process.

Background: Hereditary leiomyomatosis and renal cell carcinoma syndrome (HLRCC) is an autosomal dominant tumor predisposition syndrome with germline fumarate hydratase (FH) pathogenic variants. We describe the unusual clinical presentation, morphologic, and immunohistochemical features of bilateral renal cell carcinoma (RCC) occurring in polycystic kidneys in a 15-year-old male with HLRCC.
Case Presentation: The patient was diagnosed with bilateral polycystic kidneys at 1-year old.

The small intestine is a complex assembly of different cell types, such as enterocytes, secretory, immune, stromal and nervous cells. Due to this complexity, studying human tissue function is challenging. As surrogate systems, co-culture models have been proven to be reliable and affordable.

Rationale: Langerhans cell histiocytosis (LCH) is a rare disease involving neoplastic proliferation of myeloid precursor cells, primarily affecting bones such as ribs, pelvis, femur, and mandible with rare simultaneous involvement of the maxilla and mandible.
Patient Concerns And Diagnosis: A 48-year-old male presented with swelling and tooth mobility since 6 months. Orthopantomogram revealed extensive destruction in the mandible and right maxillary posterior region.

Hypereosinophilia is uncommon in the pediatric population and may be associated with either primary or secondary conditions. In a very small proportion of cases (less than 1%), it forms part of the initial presentation of acute lymphoblastic leukemia (ALL). More frequently, hypereosinophilia appears before overt leukemia symptoms develop, which can delay diagnosis and place affected children at increased risk due to the lack of early intervention.

Introduction: As a part of the innate immune system, eosinophils are recruited during infectious diseases, to release their characteristic cytotoxic granules and catch pathogens in extracellular traps. Moreover, eosinophils have a crucial role in autoimmune diseases, for example allergies. The isolation of these densest and lowest abundant leukocytes is cost-and labor intense.
