Presternal Bronchogenic Cysts

A congenial cutaneous bronchogenic sinus of the abdominal wall in an infant

“…In our case, the lining epithelium was pseudostratified, columnar epithelium without definite cilia identified. Although ciliated columnar epithelium was not found, the surrounding smooth muscle bundles, mucous glands and a foci of cartilage in the sinus wall supported the diagnosis of a bronchogenic origin [3,7,13]. The absence of cilia may have been due to degeneration [3,13].…”

“…Bronchogenic cysts are congenital anomalies that develop from the tracheobronchial buds of the primitive foregut [6,7]. Most cases are noted shortly after birth or during early childhood [8].…”

Scapular bronchogenic cysts in children: case report and review of the literature

“…In one theory, the bronchogenic cyst, which already exists, is accepted to be left out of the thorax after sternal closure and migrates to the cutaneous region. In another theory, the cyst simply pinches off from the developing tracheal bud during the closure of the mesenchymal plates [5,6]. Except for a few cases, no connections have been found between the cyst and the thorax in CBC cases [3].…”

“…In most cases, hyaline cartilage, smooth muscle cells, elastic fibers, fibrous tissues, neural cells and seromucous glands can be seen [5,7]. The surface epithelium is usually ciliated pseudostratified columnar or cuboidal cells but in conditions of chronic infections these structures may be changed and lymphoid follicules may be seen [7].…”

“…In the differential diagnosis of scapular CBC, lymphangioma, epidermal cysts, sebaceous cysts and aneurysmal bone cysts should be ruled out [5,7,10]. Scapular CBC have been evaluated from the dermatological and pathological point of view in most of the studies in the literature.…”
