[Orbital location of Kaposi's sarcoma]. / A propos d'une localisation orbitaire du sarcome de Kaposi.

Kaposi's sarcoma is a proliferative disease, probably induced by human herpes virus type 8 (HHV8). Its expression is cutaneous and visceral, with four clinical forms. An orbital location of Kaposi's sarcoma remains exceptional. In order to evaluate the epidemiological, clinical, and therapeutic objectives of this tumor location, we report a case of a 58-year-old patient hospitalized in the ophthalmology department for a surgically treated right orbital tumor.

[An unusual case of major restriction of eye motility: severe myopia]. / Une cause inhabituelle de restriction majeure de la motilité oculaire: la myopie forte.

Severe restrictive disorders of ocular motility are rarely described in high myopia. Their cause is still unknown. Several theories have been suggested: structural changes in the ocular muscles, sixth-nerve palsy or an elongation of the ocular globe. We report the case of a 44 years old man with high myopia of the left eye and disturbed ocular motility. Medical imaging techniques (echography, CT, MRI) allowed us to objectify the cause of ocular motility problem.

[Olfactory esthesioneuroblastoma with an ophtalmological presentation: a case report]. / Esthésioneuroblastome olfactif de révélation ophtalmologique.

Esthesioneuroblastoma (ENB) is a rare malignant tumor, which develops from the olfactory neuroepithelium and is one of the rarest tumors of the nasal cavity. Revelation by ocular signs is unusual. We report the original observation of a case of ENB of the olfactive placodes in a 28-year-old adult discovered during exophthalmia. The authors studied the clinical, radiological, pathological, and therapeutic aspects. ENB should not be forgotten in case of unilateral tumorous exophthalmia associating rhinological signs.
