A case of a 78-year-old man with transitional cell carcinoma and a paraneoplastic leukemoid reaction. The leukocytosis was present at the diagnosis of carcinoma. It dissipated with complete tumor resection, was absent when a surveillance computed tomography scan showed no evidence of recurrence at 6 months, and had returned with tumor recurrence at 8 months. This case demonstrates that a paraneoplastic leukemoid reaction can be used as a tumor marker in cases of transitional cell carcinoma when a leukemoid reaction is found at presentation.

Background: Information on the etiology and prognosis for leukemoid reaction (LR) in children is still limited and little is known about the factors that distinguish LR from hematological malignancy (HM).

Methods: This was a single-center, case-control study. Pediatric patients (<18 years) with a white blood cell (WBC) count of 50,000/μL or more were included in the study.

Article Synopsis
  • Hemorrhagic fever with renal syndrome (HFRS), caused by Orthohantavirus hantanense, presents with symptoms like fever and kidney issues, but can also involve rare conditions like acute pancreatitis and leukemoid reaction.
  • A case study of a 20-year-old male showed severe symptoms that led to hospitalization and a positive HTNV antibody test, highlighting the challenges in diagnosing HFRS when symptoms are atypical.
  • The study stresses the need for healthcare professionals to identify unusual HFRS symptoms early and use a comprehensive treatment approach to enhance patient outcomes, especially in areas where the disease is common.

Article Synopsis
  • Transient abnormal myelopoiesis (TAM) in neonates with Down syndrome (DS) presents similarly to acute megakaryoblastic leukemia but usually resolves on its own within months postpartum.
  • Some cases of TAM can lead to severe health issues, impacting the patient's prognosis negatively.
  • An autopsy of a stillborn female with TAM and DS revealed GATA1s protein expression in unusual immature megakaryocytes, indicating that placental tissue can be useful for diagnosing TAM histologically.

In clinical practice, tetracycline antimicrobial agents often lead to adverse events with drug fever and leukemoid reaction (LR) being rare occurrences. Here, we present a case of tigecycline-induced LR in a burn patient, which we believe is the first reported case of tigecycline-induced drug fever and LR globally in a burn patient and second overall.
