We describe cases of true and false median cleft combined with polyps. The polyp in the true median cleft was microscopically a skin polyp consisting of fatty tissue and was considered to be subsequent compensatory partial excess caused by impediment at the embryonic stage. The polyp in the false median cleft was considered to be a failure of the nasal septum derived from the nasal (ectethmoid) capsule. The features of these cases were considered of interest because they exhibited transient forms of the cleft. The histological findings of each polyp reflected the distinctive features of each median cleft.
