Cystic tumors involving the mucous membrane of the nasal passages, i. e., true retention cysts, are very rare, if one must form his opinion from the meagre number of reported cases, and the treatment received by this subject—or not received—in most of the classical works upon rhinology. Many of our standard authorities make no mention of this subject, either under a special caption, or under the general subject of mucous polyps. Bosworth in his great work upon the nose devotes one page and a half to the consideration of this neoplasm. Watson and Sajous devote a small space to the consideration of this growth, both referring to its rarity. Wagner reports Leffert's case in extenso.
Seiler, in a few lines, speaks of having seen this form of neoplasm and describes it "as large sessile cysts filled with the watery mucous and springing from lower border of inferior turbinate." McKenzie, Brown,
