[Hematic cyst of the masseter. Apropos of 2 cases].

An isolated swelling of the masseter raises an aetiopathogenic problem which may be encountered by any stomatologist. There are a number of diagnostic possibilities, in particular tumours. The authors report two cases with a special clinical picture: hematic cyst of the masseter. Treatment is surgical: excision via an endobuccal approach. Histological examination of the operative specimen reveals vascular dystrophy.
