[20 years later. Or, the long-term outcome of so-called mixed tumors of the lacrimal gland].

A report on two cases of long-term recurrence of mixed tumours of the lacrimal glands. The authors assess the problem of the protracted evolution of these tumours and their possible degeneration, and attempt to distinguish the degeneration which follows multiple recurrences of co-existing mixed carcinomatous tumours. They insist on the necessity in these cases of an initial wide neurosurgical exposure of the orbit, so as to perform the widest excision possible.
