It occurs when a fetal capillary bed fails to fully involute, allowing direct connection between arteries and veins.<b>&nbsp;</b>They can also happen as a result of trauma or a hormonal changes. Clinically along with swelling, they are associated with signs of warmth, palpable thrill or bruit. Management of the lesion is challenging and follows a multimodal laser therapy approach followed by embolization and surgical resection. Complete excision is required as incomplete excision leads to recurrence. A detailed clinical background combined with imaging generally clearly delineates the lesion and allows for a careful therapeutic option. A case report of a post-traumatic/acquired AVM on the upper lip is presented in this report which was diagnosed on contrast tomography Angiogram and MRI in a 7year old female and treated with intra-lesional corticosteroids followed by surgical excision.</span></span></span></span></p> Vascular anomalies, Arteriovenous malformation, Phleboliths 458 462 http://journal.zums.ac.ir/browse.php?a_code=A-10-5914-1&slc_lang=en&sid=1 Swathi Siripurapu swathisiri696@gmail.com 5200319475328460073633 5200319475328460073633 Yes Dept. of Oral Pathology, Vishnu Dental College, Bhimavaram, India Swetha Pasupuleti swetha.p@vdc.edu.in 5200319475328460073634 5200319475328460073634 No Dept. of Oral Pathology, Vishnu Dental College, Bhimavaram, India Ravikanth Manyam ravikanth.m@vdc.edu.in 5200319475328460073635 5200319475328460073635 No Dept. of Oral Pathology, Vishnu Dental College, Bhimavaram, India Kishore Moturi kishoremoturi@vdc.edu.in 5200319475328460073636 5200319475328460073636 No Dept. of Oral and Maxillofacial Surgery, Vishnu Dental College, Bhimavaram, India Divya Naga Lakshmi Puvvada puvvadadivya@vdc.edu.in 5200319475328460073637 5200319475328460073637 No Dept. of Oral and Maxillofacial Surgery, Vishnu Dental College, Bhimavaram, India
