Myeloid sarcoma (MS) is a proliferation of immature myeloid cells that occurs extramedullary, often accompanying acute myeloid leukemia (AML). It typically presents in areas such as lymph nodes, skin, and the head and neck regions. The emergence of MS within the temporal bone is rare, and it can manifest through nonspecific symptoms. In this paper, we reported a case of A 47-year-old female presented with right-sided otalgia, otorrhea, tinnitus, reduced hearing, and ear fullness, and developed facial asymmetry. She was initially diagnosed with necrotizing otitis externa and was treated accordingly. Further investigations were conducted, leading to the diagnosis of MS. She began treatment with induction chemotherapy followed by consolidation therapy. And we reviewed the literature and included 14 MS cases with the same anatomical localization, discussing the primary presentation, immunohistochemistry, and treatment approaches of these patients. In conclusion, temporal bone MS should be considered in patients with a history of AML presenting with nonspecific symptoms. Diagnostic modalities for MS include computed tomography and magnetic resonance imaging scans. Systemic chemotherapy remains the preferred treatment approach. The complexity and diversity of temporal bone MS presentations necessitate further comprehensive research to enhance understanding and improve management strategies for this rare condition., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: It is common for the liver to be supplied blood by a hepatic artery branching off the coeliac trunk. Occasionally, a replaced common hepatic artery (RCHA), emerges from the superior mesenteric artery (SMA), can supply the liver in 1.5-4.0% of cases. Computed tomography (CT) angiography is a highly accurate method for identifying arterial anomalies, which may remain undetected until the time of surgery, leading to unexpected complications., Case Presentation: A 53-year-old male exhibiting symptoms of decreased appetite, weight loss, vomiting, and altered sclera, urine, and stool colour, underwent a contrast-enhanced CT scan revealing biliary tract dilatation and pancreatic abnormalities, leading to a pancreaticoduodenectomy. During the surgery, an uncommon arterial finding-CHA from SMA-was noted. Pancreatic cancer was confirmed. The patient was discharged a week post-surgery without issues, emphasizing perioperative care progress., Discussion: The authors' study focused on the detection conditions of the same hepatic artery anomaly in eight cases reported between 2017 and 2023. In two of them the anomaly was discovered in cadaver by routine autopsy. In three cases, this variation was identified before the surgery, but in three other cases it wasn't detected until the surgical procedure. In the authors' case, due to multiple reasons, the anomaly remained undetectable until the surgery., Conclusion: This study underscores the importance of thorough preoperative evaluation to grasp vascular variations for better patient care. Also, a noteworthy observation in our case is that the surgeon identified an expanded hepatic vessel, prompting further investigation into this anomaly., Competing Interests: The authors declare that they have no conflicts of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2024 The Author(s).

Acquired hemophilia A is a rare bleeding disorder. Rapid diagnosis with prolonged aPTT and low FVIII, and immediate use of bypassing agents and steroids are crucial for better outcomes, highlighting the importance of early recognition and management., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.
