Muscle, neoplasm of, benign, 

Benign neoplasm of muscle is a non-cancerous growth that develops in muscle tissue. Benign soft tissue tumors are noncancerous lumps that develop anywhere in the body where there is soft tissue, such as muscles, tendons, and fat. 

Causes 

Here are some causes of benign neoplasm of muscle:

• Benign skeletal muscle neoplasm arises from skeletal muscle tissue.
• Intramuscular myxoma is a benign soft-tissue neoplasm that has a predilection for large muscles, being most frequently seen in the thigh.
• Leiomyomas are non-cancerous tumors that develop in smooth muscle and often happen as many painful lumps. They can start almost anywhere in the body but are most common in the gastrointestinal (GI) tract and uterus.
• Benign soft tissue tumors are noncancerous lumps that develop anywhere in the body where there is soft tissue, such as muscles, tendons, and fat. Among the most common tumors which can be classified as benign soft tissue tumors are lipoma, angiolipoma, fibroma, benign fibrous histiocytoma, neurofibroma, schwannoma, neurilemmona, hemangioma, giant cell tumor of tendon sheath, and myxoma.
• Muscle hernias are focal herniations of muscle tissue through a defect in its fascial sheath. They are most commonly found in the lower extremity. They are mostly underdiagnosed or misdiagnosed as muscle hematomas and varicosities. Chronic stress can cause muscle hernias.

Symptoms 

Benign neoplasms (non-cancerous growths) of muscle may not always cause noticeable symptoms. However, depending on their size, location, and proximity to surrounding structures, they can sometimes produce certain symptoms. Here are some possible symptoms associated with a benign neoplasm of muscle:

• Lump or mass: A visible or palpable lump or mass may be present at the site of the neoplasm. It may feel firm or rubbery to the touch.
• Pain: Some benign neoplasms can cause localized pain or discomfort, especially if they press against nerves or adjacent structures. The pain may be persistent or intermittent.
• Limited range of motion: Depending on the location of the neoplasm, it can restrict the normal movement of the affected muscle or joint. This may lead to stiffness or difficulty in performing certain movements.
• Weakness: In some cases, a benign neoplasm of muscle can cause weakness in the affected area. This weakness may affect muscle strength, leading to difficulty in performing tasks or activities that require muscular effort.
• Compression symptoms: If the neoplasm grows large enough or compresses nearby structures, it can lead to symptoms such as numbness, tingling, or a sensation of pins and needles in the surrounding area.
• Swelling or edema: In certain cases, a benign neoplasm may trigger localized swelling or edema due to its impact on lymphatic drainage or blood flow.

Diagnosis

Following are the ways to diagnose benign neoplasm of muscle:

• Intramuscular myxoma is diagnosed through imaging tests such as X-rays, MRI, and CT scans.
• Benign skeletal muscle neoplasm is diagnosed through imaging tests and biopsy.
