title: [Primary choroidal alveolar soft part sarcoma. Ophthalmopathology and histogenesis].
abstract: This is the first report on a primary choroidal alveolar soft part sarcoma in a 37-year-old male, who died 1 1/2 years following enucleation secondary to multiple metastases. Histology and differential diagnosis of this tumour are discussed. Histogenetically, because of the localization in the choroid, as far as the origin of these tumour cells is concerned, they supposedly stem from cell systems of the neuroectoderm. Since from these cell systems the malignant melanoma of the choroid arises too, a close relationship of these tumours is concluded.
