Acute Lymphoblastic Leukaemia Presenting as Bone Marrow Necrosis

Area of Science:

• Pediatric Hematology
• Oncology
• Clinical Diagnosis

Background:

• Recurrent anemia in children can be challenging to diagnose.
• Initial misattribution to malaria delayed definitive diagnosis.
• Generalized lymphadenopathy and hepatosplenomegaly are significant clinical findings.

Purpose of the Study:

• To present a case of acute lymphoblastic leukemia (ALL) with unusual presentation.
• To highlight diagnostic challenges in pediatric leukemia.
• To emphasize the importance of thorough investigation beyond initial presumptive diagnoses.

Main Methods:

• Case report detailing clinical presentation and diagnostic workup.
• Physical examination findings including lymphadenopathy and hepatosplenomegaly.
• Peripheral blood analysis, bone marrow aspirate, lymph node aspirate, and trephine biopsy.

Main Results:

• Patient presented with recurrent anemia, neutropenia, and bone marrow necrosis.
• Lymphoblasts were not evident in peripheral blood until after cytotoxic therapy initiation.
• Diagnosis of acute lymphoblastic leukemia confirmed via lymph node aspirate and bone marrow biopsy.

Conclusions:

• Acute lymphoblastic leukemia can present with atypical features, including bone marrow necrosis and delayed peripheral blood lymphoblast detection.
• Early and accurate diagnosis is crucial for effective pediatric leukemia management.
• Comprehensive hematological and pathological investigations are essential for complex pediatric cases.
