[Clinical picture and morphology of orbital rhabdomyosarcomas in children].

The clinical course of orbital rhabdomyosarcoma is described in seven male children. A survey of the literature on the subject is given. Particular attention is paid to certain diagnostic problems of this most frequent orbital malignant primary in childhood. An adequate combination therapy which results in cure in more than half of the patients should be employed provided that an exact morphological diagnosis is made; this still causes often great difficulty. Electron microscopy is of great value in distinguishing this type of tumor from other malignancies, including the so-called reticulosarcoma. In comparison with the case material of other authors, there was a relatively high rate of late deaths in our patients.
