Frequently in thecentres of round-celled polypi are found interspersed groups orentire strata of horny epidermic cells (Fig. 218, h), as well as alarge-meshed stroma in which such cells had existed at an earlierperiod. These so-called central cholesteatomata, which are chieflyfound in polypi growing from the upper segment of the tympaniccavity, may mostly be explained as sections of cornified cones sent.
