D21: Other benign neoplasms of connective and other soft tissue
The group of conditions known as other benign neoplasms of connective and other soft tissue refers to non-cancerous growths that develop in the body’s connective or soft tissues. Neoplasms, or new growths, are caused when cells multiply abnormally and excessively. In this case, the growths occur in the connective tissues that hold together and support various structures in your body, such as muscles, fat, fibrous tissues, blood vessels, and nerves. They can occur anywhere in the body as these tissues are found everywhere. Signs and symptoms associated with these benign neoplasms can vary widely depending on their location, size, and impact on nearby tissue. Some may present no noticeable symptoms while others might lead to swelling or a lump, discomfort, pain or functional disturbances. Despite not being cancerous, these growths can still cause complications, particularly if they press against vital organs, nerves, blood vessels, or other structures.
