A clinicopathological case of a 76-year-old male patient with a chronic inflammatory change of the inferior left eyelid is reported. The inflammation appeared as a reddish area of the inner part of the eyelid, without sharp limits, but with loss of lashes. Numerous local treatments did not to cure this condition. As some true eyelid tumors may mimic an inflammation during growth and, for example, sebaceous carcinoma may clinically present as chronic unilateral blepharitis, a surgical excisional biopsy was performed on this left eyelid. Its histopathological study showed a granulomatous inflammation, which was typical of a simple chalazion. This case clearly illustrates that the chalazion may not always appear as a limited nodular inflammation of the eyelid, but may have a more diffuse clinical presentation.

A clinicopathologic case of an 80-year-old male patient with a single cutaneous tumor on the upper part of the left eyelid is reported. It was a grayish and pigmented mass covered with a thick keratin layer, well circumscribed, and exophytic. After surgical removal, histopathology showed that the tumor had a papillomatous pattern and was growing under a thick layer of hyperkeratosis. It was a typical squamous cell papilloma. This tumor belongs to the benign eyelid tumor group and can be found on the eyelids of elderly people.

Introduction : Les kystes intra-vitréens congénitaux sont rares et ne causent en général pas de complications oculaires. Objectifs et Méthodes : Nous rapportons le cas d'un kyste intra-vitréen non pigmenté que nous avons suivi pendant six ans pour analyser son comportement de croissance. Observation : Il s'agit d'un patient de 62 ans suivi pour un syndrome de Morbihan qui a consulté à cause d'une ombre aperçue dans le champ visuel de l'OD. L'AV était à 1,0 corrigée. L'examen à la lampe à fente a montré la présence d'un kyste transparent flottant dans le vitré. L'ultrason a confirmé l'existence d'un kyste avec un diamètre de 4,37 mm. Ce kyste était entouré d'un deuxième kyste plus grand de 7,15 mm de diamètre. Un contrôle clinique après six ans a montré que les diamètres des kystes ont augmenté à 6.20 mm pour le petit, et 7.95 mm pour le grand kyste. Les volumes des kystes ont augmenté de 43.70 mm3 à 124,97 mm3 pour le petit et de 191.39 mm3 à 263.09 mm3 pour le grand kyste. Discussion : Étant donné que les kystes n'avaient pas d'influence sur l'acuité visuelle, aucun traitement n'a été proposé. Conclusion : Un kyste intra-vitréen non pigmenté peut augmenter considérablement en volume durant six ans d'observation.

Among corneal dystrophies, the keratoconus is one of the most frequently observed among young adults. A clinico pathological case is reported in a 13-year-old-girl of African origin. The diagnosis of bilateral keratoconus was established based on the obvious changes of the corneal curvature and thickness. After an unsuccessful attempt to improve vision with contact lenses, a keratoplasty was finally performed on one side to remove the pathological cornea. Its histopathological study found the characteristic changes of keratoconus: breaks of Bowman's layer and corneal thinning.
