Arteriovenous malformations (AVMs) are uncommon vascular lesions. AVMs are the most serious type of vascular malformations, causing substantial deformity and functional disability. AVMs of the acquired type are rarely confronted in the head and neck region. They may present as a medical emergency while performing dental procedures due to their potential for uncontrollable haemorrhage. Dental professionals should be aware of their potentially fatal complications and management. Accurate diagnosis of AVMs is critical and their management remains challenging. Vascular anomalies involving the lips can negatively impact the functionality and facial appearance. In this article, we discuss a very rare case of acquired AVM of the lower lip triggered by hormonal variation occurring during menopause in a female patient, 58 years of age. There are no reported cases of acquired AVM of the lip with hormonal variation occurring during menopause as the trigger for proliferation of the lesion. An overview of the clinical, etiological, diagnostic and management aspects of head and neck region-acquired AVMs is also presented in this paper. https://biomedpharmajournal.org/vol17no2/acquired-high-flow-arteriovenous-malformation-of-the-lower-lip-induced-by-hormonal-variation-report-of-a-rare-case-and-review/ Acquired arteriovenous malformation Lower lip Menopause Sclerotherapy Vascular malformation
