Sato and associates report 3 cases of nasal cyst with review of literature on reports of other similar cases. Judging from the locality in which these lesions occur, the connection which they have to dental and osseous tissues and from the character of inflammatory processes found in sub-epithelial structures, the authors come to a conclusion that nasal vestibular cysts are de-rivative of developmental anormaly established during fetal life. Dental abcesses may be a cau-se by which stimulation is afforded for the size increase of cysts in postnatal life.
