The infectionmust have travelled up the thoracic duct. A year later hewas in good health. The dermoid or teratomatous tumour of the testis isvery rare, and as striking in its general naked-eye featuresas the cystic form, for it contains hair and teeth {Fig. 285).It is the rarest form of all tumours of the testis. In orderto give some idea of its rarity, it may be mentioned thatduring the last thirty years only five examples have been. Fig. 285.—Embryoma of the testis in section. From a Chinese boy aged 19, inwhom it was congenital. {Muse/on, Royal College of Surgeons.) recorded by British surgeons : DArcy Power, 1887 ; JacksonClarke, 1896; Bland-Sutton, 1903; Kuhne, 1908; andBarrington, 1910. The sources of these tumours are inter-esting. Clarkes specimen was removed from a Hindu C. M. J. Giles; my specimen was removed byR. T. Booth from a Chinese student in Hankow (CentralChina); and Kuhnes came from a Chinese boy aged 4 atTungkau (China). The cavity of the teratoma (Fig. 285) contained theusual embryonal rudiment embedded in sebaceous matterand loose hair. The rudiment was composed of bone, hyalin BJSRMOIDS 543 cartilage, and a miilticuspidate tooth. The testicular tissueformed a flattened stratum outside the wall of the cyst. In its gross anatomy and structural details this tumourreveals the usual features of
