Abstract:

Purpose: Conjunctiva; It is a region where various neoplastic or nonneoplastic lesions can develop. The aim of this study is to analyze the conjunctival lesions histopathologically and to determine their prevalence. Materials and methods: Conjunctival biopsies of 401 cases who came to the pathology laboratory between 2009 and 2019 were retrospectively analyzed. The cases were histopathologically divided into 2 groups as nonneoplastic and neoplastic lesions. Neoplastic lesions were subdivided into benign, premalignant and malignant lesions. The incidence of lesions and the distribution of age and gender according to the groups were analyzed. Results: In our series of 401 cases, the mean age was 49.89±21.75 years, with 209 (52.1%) males and 192 (47.9%) females. Nonneoplastic in 296 (73.8%) cases, 105 (26%. 2) Neoplastic injury was detected in the case.  The average age in nonneoplastic lesions was 50.79±19.34, and in neoplastic lesions 47.34±27.39. Of the neoplastic lesions, 64 (60.2%) were benign, 17 (16.2%) premalign, 24 (22.6%) malign. Pterygium (n:220; 54.78) was the most common nonneoplastic injury, neurotic injury and other pigment injury (n:38; 9.5%) and the most common benign injury, and squamous cell carcinoma (n:14; 3.5%) was the most common malign injury. The incidence of neoplastic injury increased significantly over the age of 45 (p<0.05). Result: In the current study, the conjunctival lesions that have been diagnosed in our laboratory for 10 years were reviewed and a histopathological analysis was carried out. The recognition of conjunctive lesions, the recognition of nonneoplastic lesions and benign lesions and the rates of premalign and malign lesions, the planning of treatment and the preservation of visual functions, are extremely important.
