The lower part of the tumoui- contained teeth-germs in early stages of development, h, Tuft of hair. It is impossible to determine in many cases, from amere naked-eye examination, whether an ouphoronic tumourshould be regarded as an adenoma or a dermoid. In practice 494 TUMOURS OF THE OVABY the presence of a tuft of hair or a tooth is a useful and. ready-way of settling the question. Failing this, a careful micro-scopical examination is necessary. For instance, the tumourrepresented (nearly natural size) in Fig. 262 consists of twoparts; one a thin-walled cyst (filled with sebaceous materialwhen fresh) lined with piliferous skin. The lower and largerportion resembled, on superficial examiDation, an adenoma,and was nearly solid. A small tuft of lanugo-like hair in-duced me to make a careful histologic examination of theadjacent tissue. The sections revealed an extraordinarydiversity of tissues and organs, such as sebaceous and sweat-glands, hair-germs, ski
