What is myofibroblastic sarcoma?
Low-grade myofibroblastic sarcoma (LGMS) is a malignant lesion composed of myofibroblasts. It is an uncommon tumor of unknown etiology that mainly develops in the bone or soft tissue and is most often reported in the head and neck, particularly in the tongue and oral cavity.
Is myofibroblastic sarcoma cancerous?
IMT is usually benign, meaning that it is not cancer and these tumor cells usually do not travel to other parts the body. However, IMT can invade nearby tissue and cause a lot of problems. IMT can grow in the way of important organs such as the lung or stomach. In very rare cases, IMT can spread to distant organs.

What is nodular fasciitis?

What kind of tumor is low grade myofibroblastic sarcoma?
Low-Grade Myofibroblastic Sarcoma (LGMS) is low-grade malignant tumor often seen in adults. The tumors are mostly present in the extremities (arms and legs) or head and neck region. Low-Grade Myofibroblastic Sarcoma does not present pain in many cases.
Where does inflammatory myofibroblastic tumor usually occur?
It usually develops in children or young adults, but can affect people of any age. An IMT can occur in almost any part of the body but is most commonly found in the lung, orbit (eye socket), peritoneum (lining of the abdominal cavity and internal organs ), and mesentery. Signs and symptoms vary depending on the site of the tumor.

How is Inflammatory myofibroblastic tumor ( IMT ) treated?
This helps them decide which treatment is best for you. How is inflammatory myofibroblastic tumor treated?
