Bronchogenic Cervical Cyst

Clinical Findings :

A 39-yr-old man with nodular painless mass in the anterior paratracheal region of the neck. This lesion was present for several months and at ultrasonography it suggested a bronchogenic cyst.


Cytological features (Fig.1-3): In the background of clear serous material, are present non atypical ciliated columnar cells and degenerative fragments of cytoplasm, some of this containing pyknotic nuclear debris and tufts of cilia (ciliocytoforia).

Suggestion: bronchogenic cyst.

Histological picture (Fig.4-5):

Cyst, filled with serous and mucoid material, have a thin wall lined by ciliated, pseudo stratified columnar epithelium and goblet cells.
