This paper discusses the factors responsible for delayed diagnosis of malignant tumors of ethmoidal sinuses. It presents 9 cases: keratinizing type (6 cases) and nonkeratinizing type (1 case) of squamous cell carcinoma, nasopharyngeal poorly differentiated carcinoma (1 case), esthesioneuroblastoma (1 case). The diagnosis was made on the basis of a detailed study of case histories (spontaneous nasal bleeding and recurrent polyposis) and X-raying (total, contrast and tomographic). The clinical investigation was supplemented with operational green filter optics that helped detect tumor specific lesions. The final diagnosis was made on the basis of histological examinations.
本文探讨了筛窦恶性肿瘤延迟诊断的相关因素。文中介绍了9例病例：角化型（6例）和非角化型（1例）鳞状细胞癌、鼻咽低分化癌（1例）、嗅神经母细胞瘤（1例）。诊断基于对病史（自发性鼻出血和复发性息肉病）的详细研究以及X线检查（全景、造影和断层扫描）。临床检查辅以手术用绿色滤光镜，有助于发现肿瘤特异性病变。最终诊断基于组织学检查。
