Localized laryngeal lymphoma is a rare entity with an incidence of less than 1% of all laryngeal neoplasms. Diffuse large B-cell lymphoma (DLBCL) is the most common type of laryngeal neoplasms. Here, we describe a case of a young 28-year-old female with large B-cell lymphoma who remained undiagnosed for a long time owing to a myriad of nonspecific presentation including "wheezing." Although pri...
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...
INTRODUCTION C-X-C chemokine receptor type 7 (CXCR7) has recently been characterised as a novel receptor for the C-X-C motif chemokine 12 (CXCL12)/stromal cell-derived factor 1-alpha. CXCR7 has been thought to play an important role in the pathogenesis of chronic rhinosinusitis, angiogenesis and tumour metastasis. The present study aimed to examine the expression of CXCR7 in tissue samples of l...
Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...
Sarcomas account for less than 1% of malignant neoplasms arising in the head and neck in adults. Laryngeal synovial sarcoma is an extremely rare form of laryngeal malignancy with less than 20 cases reported in the literature. We report the case of a 48-year-old man with synovial sarcoma of the larynx. He underwent excision of the tumor followed by radiation. He is alive in remission at 36 month...
cosal neural sheath tumors derived from Schwann’s cells. Approximately 25 to 45% of all schwannomas present in the head and neck with most occurring in the parapharyngeal space. However, schwannomas of the larynx arising from the aryepiglottic fold, epiglottis, false or true vocal cord are quite rare, accounting for approximately 0.1% of all laryngeal neoplasms (1). It is believed to arise from...
Metastatic neoplasms in the larynx from remote primary tumors are uncommon, and laryngeal metastasis originating from the colorectum is extremely rare. We herein report a case of metastatic laryngeal carcinoma originating from sigmoid colon cancer in a 54-year-old female. Curative partial laryngectomy was performed, and the patient remains alive with a good quality of life and no signs of recur...
Sixteen biopsies of laryngeal papillomas from patients 4-21 years old, as well as tissue from scarred areas of laryngeal mucosa which previously bore papillomas, were studied with the electron microscope and compared with normal laryngeal mucosa. Tissue blocks that contained cytoplasmic bodies by light microscopy were serially sectioned for electron microscopic examination. The bodies appeared ...
BACKGROUND The differential diagnosis of endolaryngeal mesenchymal neoplasms includes a wide spectrum of benign and malignant pathologies, which have been rarely photo-documented and assessed as a group. METHODS Non-epithelial neoplasms of the endolarynx seen at our centre from 2002 to 2011 (n = 38; 36 treated at our institution) were retrospectively reviewed, with attention to clinical prese...
An exhaustive literature review of the last two decades discloses 47 laryngeal malignant neoplasms in children and adolescents. The most frequent malignant neoplasm is the embryonal variant of rhabdomyosarcoma. The timely diagnosis of a laryngeal neoplasm depends on maintaining a high index of suspicion in a patient with progressive airway obstruction, dysphagia or dysphonia, and conducting an ...
