Abstract

Primary benign orbital tumors are more common in adults, some of them may have malignant potential after 60 years. Histopathologically, benign tumors can be: congenital, fibroosseous, vascular, from nervous structures, lymphoproliferative, histiocytic, muscular, conjunctival, parasitic. In children, the most common are: dermoid cyst, epidermoid, lymphangioma, hemangioma, glioma NO. Located intra or extraconally, benign orbital tumors are clinically manifested by: irreducible exophthalmos, ophthalmoplegia, fundus changes due to tumor compression of NO. Paraclinical investigations CT, MRI, ultrasound are necessary to highlight the tumor and neighboring structures, orientation in the surgical treatment of tumor excision performed depending on the local evolution, but also on the possible malignancy. Sometimes decompression is necessary for unresectable tumors. Primary benign (and malignant) tumors may develop in the orbit secondary to tumors in the vicinity (meningioma, nasopharyngeal fibroma, mucocele). Mucocele (most commonly frontal) present in adults and the elderly requires complete excision with restoration of normal sinus drainage. The prognosis of benign orbital tumors is generally good and is related to the origin of the tumor and its location.
