Abstract

Cyst is defined as a swelling consisting of a sac filled with fluid and lined by epithelium, endothelium or granulation tissue. It can be a true or false cyst depending on the lining. A true cyst is lined by epithelium or endothelium. A false cyst is a walled off collection (not lined by epithelium) generally lined by granulation tissue and is usually inflammatory or degenerative in origin, e.g. dental or radicular cyst, pancreatic pseudocyst. This chapter describes symptoms and clinical signs of cysts with the help of clinical photographs. Classification of cysts and clinical features of various cysts, their diagnosis, treatment, management and complications are given. Aneurysm is defined as localized dilatation of segment of an artery. Aneurysm can involve large arteries like aorta, subclavian, carotid and femoral arteries or medium sized arteries like cerebral, renal and splenic arteries. Carotid body tumor is a rare tumor arising from chemoreceptor cells present on carotid bulb. Sternomastoid tumor is due to trauma to the sternomastoid muscle during birth leading to a hematoma formation. Branchial cyst, branchial fistula, pharyngeal pouch, laryngocele, subhyoid bursal cyst, cysticercosis, meningocele, myelocele, and clinical examination and differential diagnosis of a neck swelling are discussed in this chapter.
