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...

Schwannoma of the larynx is a rare entity, accounting for less than 0.1% of all benign laryngeal neoplasms. In particular, schwannoma of the epiglottis is much more rare. We report a case of schwannoma located on the laryngeal surface of the epiglottis which mimicked epiglottic cyst. A 39-year-old female presented with a 5-month history of dry cough. Laryngostroboscopy examination revealed a sm...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma ...

The incidence of laryngeal histoplasmosis is low when compared to the total number of cases. Less than 100 cases of laryngeal histoplasmosis have been described in the medical literature. Isolated laryngeal involvement may lead to the misdiagnosis and mistreatment of tuberculosis or laryngeal cancer, according to some reports. The development of hoarseness in a patient with histoplasmosis or a ...

Laryngeal sarcocystosis is an uncommon zoonotic coccidian protozoal infestation of human beings. The authors reviewed the pathology of 1,063 laryngeal biopsies over the past 10 years (2000 to 2009). Only one case of laryngeal sarcocystosis accompanying laryngeal squamous cell carcinoma was identified. The overall prevalence of laryngeal sarcocystosis was 0.094%. The case was a 66-year-old man w...

Laryngeal carcinoma and laryngeal papilloma are the most commonly encountered tumorous lesions in the larynx. Herein, we report a case of the mass arising from the left vocal cord in a 49-year-old Japanese man. Endoscopic examination suggested that the mass is a tumor such as carcinoma and papilloma. Pathological examination showed that the specimen demonstrated actinomycosis in the left vocal ...

We observed laryngeal movements in throat singing using physiological methods: the simultaneous recording of singing sounds, EGG, and high-speed digital images. We observed vocal fold and false vocal fold vibration and estimated the vibration patterns. We also estimated the laryngeal voices by using an inverse filtering method and simulated the vibration pattern using a new physical model: 2× 2...

This paper overviews studies on the production mechanism of the laryngeal voices in throat singing. Physiological observations of the larynx have clarified that ventricular fold vibration essentially contributes to the generation of the unique laryngeal voices. A physical model simulation using a two-by-two mass model supports the observed vibratory patterns of the vocal and ventricular folds. ...

Lipomas are the most common mesenchymal tumors. Laryngeal lipomas represent 1% of all lipomas but unlike other locations may cause life-threatening symptoms by obstruction of the respiratory tract. In this study, the case of a 32-year old woman with laryngeal lipoma is discussed. The lesion was detected on the left aryepiglottic fold, presented as a stalked and dynamic mass of 2 centimeters dia...

Primary laryngeal lymphoma occurs very rarely, accounting for far less than 1% of primary malignant laryngeal neoplasms. To the best of our knowledge, primary laryngeal composite lymphoma has not been reported in the literature. Herein, we report the first case of primary laryngeal composite lymphoma composed of diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma, not otherwise...
