Diverticula from the centralspinal canal forming cysts aresometimes displaced laterally, as in a case operated upon by Wolff ^- (after Hutchinson). in Central Africa, the specimen of which was examined by refers to two dermoid tumors situated in the loose connectivetissue between the peritoneum and the levator ani. Konig observedin a young girl a case of suppurating dermoid in the same location;from the tumor numerous pieces of bone, teeth, and hair 642 PATHOLOGY AND TREATMENT OF TUMORS. In rare cases such tumors are also found between the bladder and therectum. Thyroid-dermoids in the coccygeal region acquire a large size (). Middeldorpf first associated them with the post-anal gut. In theinterior of the tumor are spaces or cysts lined by columnar epithelium;these spaces contain a ropy mucus. Dermoid cysts between the rectum and the sacrum often attain greatsize, and frequently they suppurate. They are found as frequently inmen as in women. Interesting cases of dermoids in this location havebeen reported by Bryant, Ord, and Page. Open dermoids of the rectum and bladder were first described in1874 by Danzel and Martini (Fig. 465). The tumors are furnished
