Lymphoma and other lymphoid lesions of the orbit. Preliminary report

The orbit differs from the rest of the organism, excluding the central nervous system, as concerns lymph drainage. This may possible explain some of the peculiar features in lymphoid orbital lesions. The lymphoid tumours of the orbit are discussed on the basis of the classification most widely applied. An illustrative case is reported and it is concluded that even if local therapy may prove successful, patients in whom orbital lymphoid tumours have been diagnosed should be kept under constant observation with a view to prompt institution of treatment upon evidence of generalized disease.
