Acute Myeloid Leukemia (AML) is a heterogeneous group of hematologic malignancies characterized by the rapid proliferation of abnormal myeloid cells within the bone marrow and peripheral blood. Its clinical presentation can vary widely, with symptoms often mimicking those of other more common illnesses. This case study presents a unique and rare manifestation of AML, highlighting the importance of early diagnosis and tailored treatment approaches. AML is classified into various subtypes based on morphological, cytogenetic, and molecular characteristics. Despite this classification, AML remains a heterogeneous disease with a wide range of clinical presentations. The identification of unusual clinical manifestations is essential for timely diagnosis and the formulation of appropriate treatment strategies. Through a comprehensive examination of the patient's clinical history, physical examination, and diagnostic workup, we aim to shed light on the challenges and complexities encountered in diagnosing and managing AML with uncommon clinical features. The case underscores the importance of considering AML as a potential diagnosis in cases where atypical symptoms and laboratory results raise suspicion. Such instances require a multidisciplinary approach, including hematologic oncologists, pathologists, and geneticists, to guide diagnostic investigations and develop personalized treatment regimens. This report serves as a testament to the value of tailored care in optimizing patient outcomes in the context of rare presentations of AML [1].

Clinical examination

The patient, a 42-year-old male, presented to our tertiary care hospital with a two-month history of progressively worsening symptoms. He reported extreme fatigue, unexplained weight loss, night sweats, and recurrent infections. His medical history was unremarkable, with no known predisposing factors for AML, such as prior exposure to chemotherapy or radiation. Upon physical examination, the patient appeared pale, and there were palpable subcutaneous nodules on his arms and legs. Laboratory investigations revealed severe anemia, thrombocytopenia, and leukocytosis. Notably, the peripheral blood smear showed an unusual finding of circulating blast cells with irregular nuclear morphology. Further diagnostic workup, including bone marrow aspiration and biopsy, was performed. The bone marrow aspirate showed hypercellularity with a predominance of blast cells, and flow cytometry analysis confirmed the presence of myeloid blasts expressing CD34 and CD117 markers. Cytogenetic analysis revealed a complex karyotype with several abnormalities, including a rare translocation involving chromosomes 3 and 21 [2].

Treatment and outcome

The patient was promptly diagnosed with Acute Myeloid Leukemia (AML) based on the clinical presentation, laboratory findings, and bone marrow analysis. Due to the unusual cytogenetic abnormalities, a personalized treatment plan was devised in consultation with our hematologic oncology team. The patient initiated induction chemotherapy with a regimen tailored to his specific cytogenetic profile. He experienced severe cytopenias during the course of treatment, requiring supportive care measures such as red blood cell and platelet transfusions. Despite the challenges, the patient achieved remission after the first cycle of chemotherapy [3].

Subsequent consolidation therapy and hematopoietic stem cell transplantation were recommended to reduce the risk of relapse. The patient responded well to treatment, and during follow-up visits, his blood counts gradually normalized, and he regained his energy and well-being. This case highlights the importance of recognizing unusual clinical manifestations of Acute Myeloid Leukemia, as early diagnosis and appropriate treatment are critical for improving patient outcomes. The patient's presentation with subcutaneous nodules and unusual blast cell morphology in the peripheral blood smear posed diagnostic challenges, necessitating a comprehensive workup, including bone marrow analysis and cytogenetic studies. Cytogenetic abnormalities in AML are known to influence prognosis and guide treatment decisions. In this case, the complex karyotype with the rare translocation of chromosomes 3 and 21 added complexity to the management strategy. Tailoring treatment to the patient's specific genetic profile helped achieve remission and improve the overall prognosis [4][5].


This case report emphasizes the need for a high index of suspicion when encountering patients with uncommon clinical presentations, even in the absence of traditional risk factors for AML. Timely diagnosis, accurate cytogenetic profiling, and personalized treatment plans are crucial in managing AML cases with unusual clinical manifestations, ultimately offering patients the best chance for a successful outcome. Further research is warranted to explore the molecular mechanisms underlying such rare presentations of AML and to optimize treatment approaches.While AML is known for its heterogeneity, the case presented herein underscores the need for healthcare providers to remain alert to rare and atypical manifestations, as early recognition can significantly impact patient outcomes. The case serves as a testament to the significance of individualized care in managing rare presentations of AML and highlights the need for ongoing research to deepen our understanding of the molecular mechanisms driving these atypical clinical courses. Further investigations are essential to refine diagnostic criteria, identify potential genetic markers, and explore innovative therapeutic strategies that can enhance the management of AML in all its diverse manifestations. In conclusion, this case underscores the critical role of clinical acumen and collaborative healthcare teams in unraveling the complexities of AML, even when faced with rare and unusual clinical presentations. Timely diagnosis and tailored treatment are paramount in providing the best possible outcomes for patients confronting this challenging hematologic malignancy.
