In a future publication fromthe Departments of Urology and Surgical Pathology, a careful pathologicalstudy of a series of cases will be reported with a view to adding to theevidence gradually accumulating in this discussion. Occurrence in ChUdrcn.—Five of Chevassus 6i cases of teratomata. Fig. y —Left parietal pleura showing tlie spindle-shaped tumor cells. occurred in children and none of his 59 seminomes. Kober (1899) review-ing the English and German literature collected 107 cases of sarcoma ofthe testicle. In 97 of these the age was stated and only 10 occurred inchildren under ten years. (His article included one case reported in thiscountry by Deaver.) The comparatively few cases of tumor of the testisin children found after a fairly exhaustive search of the literature attest theirrelative infrequency as compared with their occurrence in adults. A few der-moids have been reported in children (Kelley). Ewing regards these asteratomatdus in nature. Steflfen and Gerhardt state that in children tumors- 7?G MALIGXAXT TUMORS OF THE TESTICLE IX CHILDREN of the testis occur chiefly in earhest infancy, generally within the first sixmonths or year, gradually diminishing in the second, third, and fourth years,and seldom occurring in later childhood.
