[Solitary bone cyst of the jaws].

The solitary maxillomandibular bone cyst is a benign bone lesion with a nontumoral osteolysis and a progressive growth potential. It is considered as a pseudocyst because of the absence of epithelium and accounts for 1% of bone cysts. Most facial solitary bone cysts are observed in the mandible, especially in the corpus, and in young patients. Its etiopathogeny is unknown. The solitary bone cyst is asymptomatic. It is often discovered accidentally by radiolucent lacuna. Adjacent teeth vitality is preserved. The differential diagnosis is that of mandibular radiolucent lacuna etiologies. The diagnosis is confirmed by the surgical approach. Treatment is based on wall cavity curettage. It is usually relatively benign but the issue is discussed in publications because of the up to 26% of recurrence, requiring radiographic follow-up.
