Experiences With Tumors of the Retina

Radiographic abnormalities in eyes with retinoblastoma and other disorders.

“…For more than a century calcareous concretions have been recognised in this neoplasm (Knapp, 1869). Depending upon the method of detection, the reported incidence of calcification within retinoblastomas varies considerably (Pfeiffer, 1936;Fulton, 1950;Merriam, 1950;Swan and Hyman, 1952;Zeiter, 1962;Bullock et al, 1977) (Table 1). Bullock et al (1977) reported radiodensities in only 19% of cases on standard preoperative roentgenograms, but in ashed tissue blocks with 8 retinoblastomas they found the calcium content in all instances to be much higher than in 4 normal eyes.…”

“…Le naevocarcinome ou mélanome malin d'origine naevique est une tumeur rare (Mériyot de Treigng, 1939;Swan, 1948;Kesinger, 1950;Reese, 1951). 11 a souvent été classé parmi les sarcomes de la conjonctive : c'est ainsi que Lies ko (1922) a écrit que ces derniers peuvent se développer à partir des vaisseaux, mais également à partir des naevi.…”
