[Spontaneous growth inhibition in retinoblastoma].

Report on 8 cases with spontaneous arrest of retinoblastoma. The incidence was 3.2% which is approximately 1000 times more than in other malignant tumors. Multifocal lesions suggesting that this form of "regression" may not be a regression at all. Spontaneous arrest of retinoblastoma is obviously a lesion of low malignant potential. The presence of a spontaneous arrest of retinoblastoma necessitates genetic counselling and examinations of the eyes in the offspring. Synonymous names are: 1. Spontane Rückbildung eines Retinoblastoms (spontaneous regression of retinoblastoma), 2. Retinoma, 3. Retinocytoma, 4. benign variant of retinoblastoma, 5. spontaneous arrest of retinoblastoma, 6. spontaneous cure of retinoblastoma.
