title: [Elements of photoreceptors in retinoblastomas (author's transl)].
abstract: In 3 cases of 29 retinoblastomas (roughly 10%) structures similar to processes of photoreceptors were found. In each of them so-called fleurette cells were seen. In one case, described in detail, many lamellar structures appeared corresponding to the outer segment of the photoreceptor.
