Clinical, epidemiological and anatomopathological aspects of palpebral-conjunctival tumours in the Ophthalmology department of the Amirou Boubacar Diallo National Hospital in Niamey

Palpebro-conjunctival tumors are not negligible in frequency, their clinical presentation is ambiguous, and their diagnosis relies on determination of their anatomopathological nature by biopsy. The aim was to study the clinical, epidemiological and anatomopathological aspects of palpebro-conjunctival tumours in the Ophthalmology Department of the Niamey HNABD. Methodology: this was a prospective descriptive and analytical study, conducted over a 5-year period from 01 January 2019 to 31 December 2023. Cases of palpebro-conjunctival tumors received in the ophthalmology department of the Niamey HNABD during this period were included. Results: The overall incidence was 1.33%. The most common age group was 0-9 years, with an average of 25.11 ± 24.45 years, and extremes of 10 days and 96 years. 52.92% of patients were female. Nearly a quarter of patients (31.02%) were students. The left eye was most affected in 51.76% of cases. The upper eyelids were affected in 48.60%. Tumours were benign in 80.28%, malignant in 14.79%, indeterminate malignant in 4.58% and precancerous in 0.35%. Squamous cell carcinomas accounted for 33.33% of malignant tumours. Chalazions accounted for 40% of benign tumours. The tumors were palpebral in 86.97% and conjunctival in 13.03%. Conclusion: Palpebroconjunctival tumours are relatively common, with a wide variety of histological characteristics in our context. Keywords: palpebral-conjunctival tumors, Niger.
