In this stalk were numerous blood vessels, agreat many hair follicles and many sebaceous gland cells surrounded by fat(Fig. 11). Most of the hair follicles pointed directly toward the interior ofthe tumor, evidently to discharge their hairs within it, although in addition tothe hairs seen in cross section, inside the tumor there were others which hadbeen cut across as they lay in the wall. At one point in the outer connectivetissue layer a small area of osteoid tissue was present (Fig. 12). 17. For areas in tumor where microphotographs were taken, compareFigure 14.
