Immunophenotypically, the EBPs are commonly myeloid as compared to the lymphoid. Amongst the lymphoid EBPs, T\u2010lymphoblastic type is considerably rare. Furthermore, the occurrence of EBPs at the initial clinical presentation is extremely rare and such presentations almost always portend the occurrence of an imminent hematological blast crisis shortly.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case<\/jats:title><jats:p>A 25\u2010year\u2010old male presented with abdominal fullness for 1\u2009month. There was no history of abdominal pain, vomiting, jaundice, weight loss, or night sweats. On clinical examination, the patient was found to have pallor and was febrile. There was hepatosplenomegaly and a single, firm, mobile, left posterior cervical lymph node measuring 1.5\u2009\u00d7\u20091\u2009cm was palpable. Routine blood counts revealed anemia, leukocytosis, and thrombocytopenia. A fine\u2010needle aspiration (FNA) from the cervical revealed T\u2010lymphoid EBP, confirmed by flow cytometry. Subsequently, his bone marrow examination revealed a diagnosis of CML with <jats:italic>BCR::ABL1<\/jats:italic> fusion. Thus, a final diagnosis of CML with extramedullary T\u2010lymphoid blast crisis localized to the cervical lymph node was rendered.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The present report, besides highlighting the utility of FNA cytology in rendering such challenging diagnoses, also reiterates the significance of ancillary techniques, such as flow cytometry, which play a key role in early diagnosis and exact characterization of such rare and aggressive hematolymphoid neoplasms.<\/jats:p><\/jats:sec>","DOI":"10.1002\/dc.25372","type":"journal-article","created":{"date-parts":[[2024,6,18]],"date-time":"2024-06-18T06:30:57Z","timestamp":1718692257000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Extramedullary
