Histologically these are also composed of cartilage, smooth muscle, fibrous tissue and mucous glands. These cysts originate from the ventral foregut that forms the respiratory system. These cysts are located close to the trachea or main stem bronchi. Rarely there is communication of the cyst with the tracheobronchial tree. Clinical features These cysts are found most often in young adults and are rare in infancy. The usual symptoms are the result of compression by the cyst, e.g., dyspnoea, dysphagia, cough and chest pain. Malignant degeneration has been reported in these cysts on rare occasions. Chest x rays show a smooth density just in front of the trachae or main stem bronchi at the carinal level. When the cyst communicates with the tracheobronchial tree, the air fluid level may be seen within the cyst. CT scanning is useful in localising these cysts. Treatment wikt excision Excision provides definitive diagnosis and cure. Biopsy provides definitive diagnosis with less surgical risk. Observation provides minimal risk from the intervention, but carries some risk of bleeding or infection of the cyst at a later time, making excision more difficult if it occurs.

The cyst cavity is lined by epithelial cell s derived from the reduced Tooth enamel enamel epithelium of the tooth forming organ. Regarding its pathogenesis , it has been suggested that the pressure exerted by an erupting tooth on the follicle may obstruct venous flow inducing accumulation of exudate between the reduced enamel epithelium and the tooth crown . In addition to the developmental origin, some authors have suggested that periapical inflammation of non vital deciduous teeth in proximity to the follicles of unerupted permanent successors may be a factor for triggering this type of cyst formation. Histologically a normal dental follicle is lined by enamel epithelium, whereas a dentigerous cyst is lined by non keratinized stratified squamous epithelium. Since the dentigerous cyst develops from follicular epithelium it has more potential for growth, differentiation and degeneration than a radicular cyst. Occasionally the wall of a dentigerous cyst may give rise to a more ominous mucoepidermoid carcinoma. Due to the tendency for dentigerous cysts to expand rapidly, they may cause pathological fractures of jaw bones. The usual radiographic appearance is that of a well demarcated radiolucent lesion attached at an acute angle to the cervical area of an unerupted tooth. The border of the lesion may be radiopaque. The radiographic differentiation between a dentigerous cyst and a normal dental follicle is based merely on size. Radiographically, a dentigerous cyst should always be differentiated from a normal ... the cyst appears unilocular with well defined margins and often sclerotic boarders ... more details
