Phlebolith in arteriovenous malformation in buccal fat pad masquerading sialolith: A rare case report.

Arteriovenous malformations (AVMs) are rare vascular lesion in the buccal fat pad (BFP). One of the important complications associated with these lesions is phlebolith formation within it. To the best of authors' knowledge, there is no medical literature on AVM with phlebolith formation in BFP till date. The present case is a 12-year-old boy who presented with a swelling in the right side of the face, clinically diagnosed to be sialocele with sialolith. Excision of the mass was done, and histopathology revealed AVM with the formation of phlebolith. This rare entity needs to be kept in mind while evaluating a case of calcification in BFP. The first case of AVM with phlebolith formation in BFP is reported here along with brief review of literature.
