Laryngeal cancer represents one third of all head and neck cancers and can be a significant source of morbidity and mortality. Laryngeal cancer includes cancers arising primarily from any form of laryngeal papillomatosis LP, also known as recurrent respiratory papillomatosis RRP, and is the most common benign mesenchymal neoplasm of the larynx in children. RRP is characterized, lipomas grow from fat cells and are the most common type of benign tumor. One of these will develop a lipoma during their lifetime. They are often found on the back, shoulders, arms or neck. Resume. The clivus is an anatomical structure located at the midline in the central skull base. It is affected by a wide range of non-neoplastic, benign and malignant pathologies, some of which commonly affect the clivus due to its strategic location and embryological origin. Clival lesions can often be asymptomatic with occasional complaints such as. Ganglia are the most common soft tissue 'tumor' of the foot and ankle. ganglion is a cyst containing mucous fluid.
