Background: Acquired haemophilia A is caused by the development of an autoantibody to factor VIII in a person with previously normal haemostasis. The most common clinical presentation in hereditary haemophilia is intra-articular bleeding. In contrast, acquired haemophilia more commonly presents with skin, soft tissue and mucosal haemorrhages.
Methods: We present a case of a patient with idiopathic acquired haemophilia A, whose initial presentation was that of spontaneous submental and submandibular haematoma which rapidly progressed to involve multiple sites in the airway, ultimately necessitating an emergent tracheotomy. In view of the extremely rare occurrence of this phenomenon, a systematic review and summary of all previously reported cases is also presented.
Results: The diagnostic and management dilemmas encountered in this case are presented from an otolaryngologist's perspective.
Conclusions: Otolaryngologists' awareness of underlying haematological pathologies and their natural course of disease in cases of severe airway haemorrhage is of paramount importance in anticipating evolving issues in management of these patients.

Hemophilia A is a clotting disorder due to factor VIII deficiency, leading to prolonged bleeding. Acquired hemophilia A results from the immune system attacking factor VIII, typically occurring later in life. Factor V Leiden is a genetic mutation causing abnormal blood clot formation, primarily in veins.

Katharine Dormandy Haemophilia and Thrombosis Unit, Royal Free Hospital, London, UK.
Background: Acquired haemophilia A (AHA) is an acquired bleeding disorder resulting from autoantibodies against Factor VIII (FVIII). Previous studies have reported differences in FVIII inhibitor kinetics (type I or type II) in AHA compared to severe haemophilia A.
Aim: To characterise inhibitor kinetics in AHA and evaluate the proportions displaying type I, II or indeterminate kinetics.
Acquired factor V inhibitor in a case of pediatric venous thrombosis.
Res Pract Thromb Haemost
January 2025
Department of Pediatric Hematology, Innovative Hematology, Indiana Hemophilia and Thrombosis Center, Indianapolis, Indiana, USA.
Background: The development of acquired factor (F)V with inhibitor (AFVwI) is rare, resulting mainly in bleeding complications, although sporadic cases of thrombosis in adults have been reported.
Key Clinical Question: How do you diagnose and manage a pediatric case of acute deep venous thrombosis associated with the concurrent finding of AFVwI?
Clinical Approach: A 13-year-old female with Crohn's Disease and May-Thurner anatomy developed extensive deep venous thrombosis of the left lower extremity, complicated by the finding of AFVwI, discovered during the evaluation of a prolonged prothrombin time and a low FV activity. Anticoagulation was initiated with low-molecular-weight heparin followed by a direct oral anticoagulant, rivaroxaban, without any complications.

This perspective discusses the critical role of laboratory assessments in assessing factor VIII (FVIII) inhibitors. These are auto- and alloantibodies that can develop against both endogenous and exogenous FVIII, respectively. Assessment for inhibitors represents a key part of the management of both congenital hemophilia A (CHA), an inherited deficiency, and acquired hemophilia A (AHA), an autoimmune condition.
