[Ophthalmic arteries originating from external carotid arteries].

The ophthalmic artery arises from the internal carotid at the level of the carotid siphon; in 3.5-5% of the population, it arises from the middle meningeal artery, a branch of the internal maxillary artery, terminal of the external carotid artery. We report a rare case of bilateral malformation in a 28-year-old patient. Our study covers the possible dual origin of orbital blood vascularization. This variation in the anatomic distribution is important to know, particularly if embolization is intended as inadvertent occlusion of the ophthalmic artery, because it may lead to permanent loss of vision.

[Tumors of the eyelids in the elderly].

The clinical aspect of tumors of the eyelids is polymorphous; however, the most frequent are benign tumors such as papillomas, basal cell carcinoma, squamous cell carcinoma, meibomian gland carcinoma, and melanomas. An important step in the management of the malignant types is to try to establish clear margins through histopathologic techniques: the Mohs technique, the rapid fixation technique, and the frozen section method are the most frequent technical tools used today. For the most malignant tumors such as malignant melanoma and Merkel cell tumor, lymph sentinel biopsy is a recent, valuable tool, but its benefit needs to be confirmed in large series.
