Cases of Larynx Disease and Ventricular Carcinoma that were Difficult Diagnosis

Abstract

Among laryngeal cancers, which are often difficult to identify and diagnose, there is the possibility for cases of glottic cancer, similar to laryngeal polyps or cysts, and ventricular carcinoma of the larynx with swelling of the false fold. In the present case, we treated a patient with a lesion ventricular carcinoma, that was difficult to detect and diagnosed. The mass did not exhibit the characteristics of ventricular carcinoma to in the larynx and was instead located in the deep portion of the laryngeal ventricle; therefore, its discovery was delayed . In addi-tion, only swelling of the false fold was observed under an endoscope and the lesion may progress, requiring la-ryngectomy, during follow up. Ventricular carcinomas often progress in the top and bottom of the glottis region within the paraglottic space, making it difficult to detect such tumors early. In addition, ventricular carcinomas easily develop lymph node and distant metastaseis. We herein report the cases of the patient with false fold swelling who were found to have ventricular carcinoma of the larynx, and discuss the clinical and pathological characteristics of the tumor.
