Cystic lesions of the maxilla are benign entities with both odontogenic and non-odontogenic origins. The maxillary cyst is a benign tumor of the bones of the jaw, which has a membrane and contains a fluid, semi-solid or mixed (liquid / semi-gaseous) material. These often lead to deformities in the jaw area. Cases are specific by framing pathological rarity, etiology, pathogenesis and clinical symptoms.
Considering the large entity of cystic formations that can be found in the maxilla region, we selected two patients with cystic formations of the upper jaw, which were part of different pathological etiology categories, with special rarity occurring, evolutionary appearance and difficult to classify in terms of pathognomonic signs.
