854 lesions involving the eye and adnexa in the Sudan were studied as regards their frequency, sex and age incidence, site, pathologic types and geographic and racial distribution. Of 279 primary malignant tumors (frequency ratio 4.3%), conjunctival squamous carcinoma was the commonest (50.4%) while retinoblastoma formed 20.8%, basal cell carcinoma 6.1% and malignant melanoma 4.6%. Conjunctival carcinoma and allied epithelial lesions occurred much more predominently in Northern than in Southern Sudan and no basal cell carcinoma of the eyelids was recorded in the latter. Retinoblastoma and melanoma showed certain tribal predilections. Most cases of Burkitt's lymphoma occurred in Southern Sudan. It is concluded that geographic and racial factors play important roles in determining the frequency and pattern of eye neoplasms in the Sudan.
对苏丹854例累及眼及附属器的病变进行了研究，涉及发病频率、性别和年龄发病率、部位、病理类型以及地理和种族分布。在279例原发性恶性肿瘤中（频率比为4.3%），结膜鳞状细胞癌最为常见（50.4%），而成视网膜细胞瘤占20.8%，基底细胞癌占6.1%，恶性黑色素瘤占4.6%。结膜癌及相关上皮病变在苏丹北部比南部更为多见，苏丹南部未记录到眼睑基底细胞癌。成视网膜细胞瘤和黑色素瘤表现出一定的部落偏好。大多数伯基特淋巴瘤病例发生在苏丹南部。结论是地理和种族因素在决定苏丹眼部肿瘤的发病频率和模式方面发挥着重要作用。
