The two main forms of amyloidosis are systemic and localized; the latter is rare. No satisfactory treatment for systemic amyloidosis has been discovered, and mean survival is poor, ranging from 5 to 15 months dep...

UNLABELLED Lipomas are the most common benign soft tissue mesenchymal tumours composed of mature adipose tissue. They are uncommon in the oral and maxillofacial regions, with 15-20 % of cases involving the head and neck region and less than 5% of all benign oral lesions. Multiple symmetric lipomatosis is rare and characterized by diffuse growth and nonencapsulated lipomas. It is usually found i...
