[Traumatic cyst of the mandible. From development to therapy - a case report].

Abstract

Traumatic bone cysts, also referred to as simple bone cysts, solitary bone cysts and haemorrhagic bone cysts, are intraosseous pseudocysts and are categorized by the WHO (2005) as benign, bone-related lesions. Most often young patients under the age of twenty are affected. Symptoms are uncommon and normally the lesion is found in routine radiographic examinations in the mandible. The etiology is still unknown and it has been discussed that trauma, benign tumours or abnormal bone growth might be the cause. Surgical treatment is recommended and recurrence is rare. Histologic features of pseudocysts are a lack of lining epithelium and often an empty bone cavity can be found. The following case report presents a traumatic cyst in the mandible of a 14-year old female patient. Clinical, radiological and histopathological characteristics of this entity will be discussed as well as therapy and follow-up.
