Owing to its heterogeneous and often indolent initial presentation, diagnosis is frequently delayed, potentially worsening prognosis. We report the case of a 55\u2010year\u2010old man with long\u2010standing underrecognized cutaneous and nodal lesions that eventually evolved into disseminated BPDCN. The patient was successfully treated with intensive chemotherapy (CHT) using a hyper\u2010CVAD regimen combined with intrathecal therapy (IT), achieving complete remission (CR). Consolidation with allogeneic hematopoietic stem cell transplantation (allo\u2010HSCT) from a matched sibling donor resulted in sustained minimal residual disease (MRD)\u2013negative CR. At 23\u2009months post transplant, the patient remains disease\u2010free with full donor chimerism and no evidence of graft\u2010versus\u2010host disease (GvHD). This case highlights the diagnostic challenges of BPDCN, the importance of early recognition of atypical cutaneous lesions, and supports the role of intensive CHT followed by allo\u2010HSCT as an effective therapeutic strategy in eligible patients.<\/jats:p>","DOI":"10.1155\/crh\/4591883","type":"journal-article","created":{"date-parts":[[2026,7,18]],"date-time":"2026-07-18T09:05:04Z","timestamp":1784365504000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impressive
