One of the reasons for the development of such conditions is acquired hemophilia. Aim: Identification of the mechanisms of development of the acquired inhibitory form of hemophilia A in elderly patients using the example of our own clinical observation. Material and methods: Analysis of a clinical case and analysis of current scientific literature. Results: The presented clinical case allowed us to study the pathogenesis, principles of diagnosis and treatment of acquired coagulopathy. Conclusions: Knowledge about the development mechanisms and features of the course of the acquired inhibitory form of hemophilia A should help the clinician in the early diagnosis of this coagulopathy and, as a consequence, the timely initiation of treatment aimed at preserving the patient’s life.</p></abstract><trans-abstract xml:lang="ru"><p>Образование циркулирующих аутоантител, способных ингибировать факторы свертывающей системы крови, сопровождается возникновением спонтанных и/или посттравматических кровотечений у больных без предшествующих нарушений системы гемостаза в анамнезе.
