Laryngeal neoplasms represent 2% of all human cancers. They befall mainly the male sex, especially between 50 and 70 years of age, but exceptionally may occur in infancy or extreme old age. Their occurrence has increased considerably inclusively due to progressive population again. The present work aims at establishing a relation between this infirmity and its prognosis in patients submitted to...

tuberculosis is a major health problem in iran and its laryngeal involvement is not uncommon. laryngeal tuberculosis is so infectious and delay in diagnosis and treatment could result spread of disease and causes divesting complications. we reviewed clinical and para-clinical characteristics of patients with laryngeal tuberculosis in iran. in a cross sectional study, patients with laryngeal tub...

From 1965-1978 over 2,700 patients were admitted to the Massachusetts Eye and Ear Infirmary or the Massachusetts General Hospital with carcinoma of the oropharynx, larynx or nasopharynx; only 36 of these patients were less than 40 years of age. Twelve patients had oropharyngeal carcinoma, 13 patients had laryngeal or hypopharyngeal carcinoma, and 11 patients had nasopharyngeal carcinoma. Analys...

Sarcomas represent less than 1% of malignant laryngeal tumors and giant cell malignant fibrous histiocytoma is exceptionally rare. Diagnosis is histologically based and immunohistochemistry allows differentiation from other fibro-histiocytic neoplasms. We present the case of a 53-year-old male patient with positive medical history for trichinellosis and tuberculosis, and a laryngeal tumor invad...

Conflict of interest: non-existent One of the reasons why this procedure is sometimes necessary when a person remains without these important structures is when cancer occurs1. According to data from INCA-National Cancer Institute, Brazil has a high incidence of laryngeal mal...

Laryngeal carcinomas are aggressive neoplasms with controversial association with the human papillomavirus (HPV) and Epstein-Barr virus (EBV). So far, the impairment of p53 protein function and its impact on cellular proliferation has not been studied adequately in these tumors. In this work, molecular biologic techniques were used to assess the frequency of HPV and EBV in 110 squamous cell car...

Introduction Granulocytic sarcomas, also referred to as chloromas or myeloid sarcomas, are extramedullary neoplasms that are composed of immature myeloidcells.Thetermchloromareferstothegreencolorthat is imparted to the tissues as a result of the high concentration of myeloperoxidase foundwithinthetumorcells. These tumors typicallyoccur inassociation with nonlymphocytic leukemias or myelodysplas...

Neuroendocrine tumors are the most common nonsquamous types of laryngeal neoplasms. They are classified as typical carcinoids, atypical carcinoids, small-cell neuroendocrine carcinomas, and paragangliomas. The aim of the paper is to present four patients with small-cell neuroendocrine tumor arising in larynx. There were one woman and three men whose ages were 47-77 years; all of them had metast...
