A Case of Lingual Demoid Cyst

Abstract

Dermoid cysts are congenital lesions derived from the ectodermal differentiation of multipotential cells. A full-term baby boy was observed to have a firm, nontender lingual mass, present at birth. There was a thick-walled cyst measuring 1 cm on the inferior aspect of the tongue extending from the tip posteriorly. The child was gradually having difficulty in sucking and moving his tongue. At one month of age, the mass was surgically excised. After partial decompression by aspiration, the cyst, which was about 3 cm in diameter, was completely excised. The postoperative course was unremarkable. Pathology revealed a benign cyst, lined with squamaous epithelium and columnar epithelium that was partially ciliated, containing scattered mucinous cells.
