Carcinome épidermoïde conjonctival invasif: à propos de 2 cas / Invasive squamous cell carcinoma: about 2 cases

Les tumeurs conjonctivales sont fréquentes dans les zones tropicales,où l'exposition aux rayons ultraviolets est forte et quasi permanente. Les tumeurs malignes sont assez rares et la plus représentée est le carcinome épidermoïde de la conjonctive.Nous rapportons deux cas de carcinome épidermoïde invasif de la conjonctive reçus dans le service d'ophtalmologie de l'hôpital Sominé Dolo de Mopti au Mali. Il s'agissait de deux patientes de 25 et 51 ans, vivant en zone rurale et désertique exposées aux rayons solaires et à la poussière. Elles présentaient une masse développée dans l'aire de la fente palpébrale, envahissant la cornée et empêchant l'occlusion palpébrale. La masse était en relief, multi lobulée, bien circonscrite, de couleur blanc nacré et d'aspect papillomateux avec une dilatation des vaisseaux nourriciers. Une exérèse chirurgicale large à 4 - 5 mm des berges de tissu sain a été réalisée avec examen anatomopathologique de la pièce qui a confirmé un carcinome épidermoïde différencié mature et invasif de la conjonctive. Le bilan d'extension et la sérologie HIV étaient négatifs. L'évolution était favorable à moyen terme sans récidive

Conjunctival tumors are common in tropical areas, where exposure to ultraviolet radiation is high and almost permanent. Malignant tumors are quite rare and the most represented is conjunctival squamous cell carcinoma. We report two cases of invasive squamous cell carcinoma of the conjunctiva received in the ophthalmology department of the Sominé Dolo hospital in Mopti, Mali. The patients were 25 and 51 years old, living in a rural desert area exposed to sunlight and dust. They presented with a mass developed in the area of the palpebral fissure, invading the cornea and preventing palpebral occlusion. The mass was raised, multi-lobulated, well circumscribed, pearly white in color and papillomatous in appearance with dilation of the feeder vessels. A wide surgical excision at 4 - 5 mm from the healthy tissue edges was performed with anatomopathological examination of the specimen, which confirmed a mature and invasive differentiated squamous cell carcinoma of the conjunctiva. The extension workup and HIV serology were negative. The evolution was favorable in the medium term without recurrence

[Eye traumatism during the COVID-19 sanitary crisis at Iota-teaching hospital]. / Traumatismes oculaires pendant la crise sanitaire de COVID-19 au CHU de Iota.

INTRODUCTION: During the COVID-19 pandemic, we have witnessed a world-wide lock-down of the population. This government action combined with the application of social distancing should in principle reduce the frequency of occurrence of ocular injuries. The goal of our work is to try to understand the circumstances of the occurrence of ocular injuries at the IOTA Teaching Hospital during the lock-down period of the COVID-19 health crisis. METHODOLOGY: This was a cross-sectional, descriptive study. The data were collected prospectively. Our study covered the period from March to May 2020. All consenting patients seen at the IOTA Teaching Hospital for ocular trauma regardless of gender, age, circumstances in which the trauma occurred or the nature of the injuries were included by non-probability sampling. Excluded from the study were patients who did not consent or who consulted for a non-traumatic ophthalmologic condition. RESULTS: There were a total of 138 cases, of which 84 were male and 54 female, for a gender ratio of M/F=1.5. Children aged 0 to 5 years represented more than 3/4 (79.14%) of our sample. Trauma occurred in 45.83% of cases during leisure activities and 3.60% of cases involved domestic violence. DISCUSSION: According to the authors, measures aimed at limiting public movement, particularly the curfews introduced by the Malian government to contain the spread of the COVID-19 pandemic, may actually result in trauma. CONCLUSION: Raising public awareness of the social and psychological consequences of lock-down through audiovisual means might significantly reduce the frequency of these ocular traumas.
