[34 epibulbar malignant tumours (author's transl)]

Based on a study of 34 cases, the authors make therapeutical and diagnostical references concerning the epibulbar malignant tumours. These were met with a frequency of 10% of the total amount of the malignant tumours of the visual apparatus. The most frequent setting were at the level of the bulbar conjunctiva and of the sclero-corneal limb, especially in front of the opening of the palpebral slit and in the temporal area. The histological examination of the tumours pointed out the following morphological types; epitheliomas (61%), especially spino-cellular, malignant melanomas (32%) and sarcomas (6%). The therapeutical attitude was the surgical one -- the accurate extirpation -- in the limited tumours, followed by radiotherapy when neoplasic lesions were found at the limit of section. In the invaded tumours, the exenteration of the orbit was performed followed by radiotherapy. On the terms of such a therapeutical conduct, the distant prognosis proved to be dependent on two factors: a. The early diagnosis, that is the stage of the therapeutical action. It is insisted upon the importance of the signs of malignization of some benign tumors: papillomas or naevi. b. The nature and origin of the tumour: the secondary tumours are more severe from the beginning.
