Tumours are abnormal tissue growths that can occur in any part of the body. Muscle tumours are a specific type of tumour that can either originate in muscle tissue or spread to it. While some muscle tumours are benign, others are malignant and can grow to great proportions. One such type of malignant muscle tumour is leiomyosarcoma (LMS), a rare and aggressive cancer that grows in smooth muscles, including those in the abdomen and uterus. LMS is a type of soft tissue sarcoma, a rare cancerous tumour that develops in the tissues supporting and surrounding bones and organs. Soft tissue sarcomas can be challenging to diagnose and often require imaging scans and biopsies for accurate detection. Treatment options include surgery, radiation therapy, and chemotherapy.

What You'll Learn
Leiomyosarcoma: a rare cancer that grows in smooth muscles
Leiomyosarcoma, or LMS, is a rare type of cancer that grows in smooth muscles. Smooth muscles are found in the hollow organs of the body, including the intestines, stomach, bladder, and blood vessels. Females also have smooth muscle tissue in the uterus. These smooth muscle tissues help move blood, food, and other materials through the body without us being aware.
LMS is an aggressive cancer, meaning it can grow quickly. It is most commonly found in the abdomen or uterus. It is a type of soft tissue sarcoma and makes up between 10% and 20% of soft tissue sarcoma cases. Soft tissue sarcomas are rare cancerous tumours that develop in the tissues supporting and surrounding bones and organs, including muscles, tendons, and fat cells. They usually appear in the arms, legs, chest, and back of the belly or retroperitoneum.
LMS tumours can be large, and they may spread to other parts of the body. Symptoms depend on the tumour's location and size. Diagnosis of LMS involves imaging scans such as MRI, CT, angiography, and PET to determine the tumour's size and location. A biopsy is also performed to confirm LMS, where a small sample is taken from the tumour and studied under a microscope.
The best treatment option for LMS is surgery, with a good chance of cure if the entire tumour is removed. Radiation therapy can be used around the time of surgery to prevent tumour regrowth. Chemotherapy is employed when LMS tumours are large or have spread to other body parts.

Liposarcomas: malignant tumours of fat tissue
Liposarcomas are malignant tumours of fat tissue. They are a type of soft tissue sarcoma, a rare form of cancer that develops in the tissues supporting and surrounding bones and organs. Soft tissue sarcomas can develop in muscles, tendons, fat cells, nerves, fibrous tissues, blood vessels, and deep skin tissues. Liposarcomas, in particular, are malignant tumours that arise from fat cells and can develop anywhere in the body. However, they are most commonly found in the thigh, behind the knee, and inside the abdomen.
Liposarcomas are typically observed in adults between the ages of 50 and 65. They are characterised as round or oval-shaped lumps or bumps that emerge slowly or quickly in any part of the body. These lumps are generally painless unless they compress a nerve or irritate other tissues. While liposarcomas are malignant, it is important to note that benign masses are believed to occur ten times more frequently than cancerous growths.
The diagnosis and treatment of liposarcomas are crucial. While a newly discovered soft tissue mass is rarely an emergency, any suspected cancerous growth should be promptly evaluated and biopsied. Imaging scans such as MRI, CT, angiography, and PET are used to determine the location and size of the tumour and to check for signs of spread to other body parts. A biopsy involves taking a small sample from the tumour to confirm the presence of liposarcoma.
The treatment options for liposarcomas include surgery, radiation therapy, and chemotherapy. Surgery offers the best chance of cure when the entire tumour is removed. Radiation therapy is employed to prevent tumour recurrence after surgery. Chemotherapy is used in combination with surgery when the tumour is large or when cancer cells have spread to other areas.
It is important to consult a healthcare provider if you identify any potential symptoms or risk factors associated with liposarcomas or soft tissue sarcomas. Early detection and treatment improve the chances of successful management.

Leiomyomas: benign tumours of smooth muscle
Leiomyomas are benign tumours of smooth muscle. They can be found anywhere in the body but are very common in the walls of the uterus, where they are known as fibroids. Leiomyomas are also found in the ovaries, fallopian tubes, the alimentary canal, bladder, and ureters. Smooth muscle tissues help move blood, food, and other materials through the body.
Leiomyomas are firm or rubbery tumours that can be easily removed. Although part of the tumour may become malignant, it usually does not spread nor recur once removed. Leiomyomas are one of the three major types of muscle tumours, the other two being rhabdomyomas and rhabdomyosarcomas.
Rhabdomyomas are rare, usually benign tumours of striated (striped) muscles. They most commonly occur in the heart. Some forms of this tumour spread, with metastases occurring in the uterus, bladder, prostate, oesophagus, digestive tract, and kidneys. Rhabdomyomas affecting other parts of the body commonly involve both smooth and striated muscles. Many of these mixed tumours are likely to be malignant and may grow to great proportions.
Rhabdomyosarcomas are malignant tumours that arise in skeletal muscles. Most tumours of this type are located in the leg or arm muscles. A rhabdomyosarcoma may recur even after amputation of the involved extremity. The only symptom may be a slowly growing mass, which usually has been growing for 10 or more years before it is discovered.
Soft tissue sarcomas are rare cancerous tumours that develop in the tissues that support and surround bones and organs. They can develop in muscles, tendons, fat cells, nerves, fibrous tissues, blood vessels, or deep skin tissues. They usually develop in the arms, legs, chest, and back of the belly. Soft tissue sarcomas can be serious and are more successfully treated if diagnosed before they spread.

Rhabdomyomas: benign tumours of skeletal and heart muscle
Soft tissue tumours are cell growths that can appear anywhere in the body, including muscles, tendons, ligaments, cartilage, nerves, blood vessels, fat, and other tissues. They can be benign or cancerous.
Rhabdomyomas are a type of rare, usually benign tumour of skeletal and heart muscle. They are one of the three major types of muscle tumours, the other two being leiomyomas and rhabdomyosarcomas. Rhabdomyomas are tumours of striated (striped) muscles. They most commonly occur in the heart, growing in the wall and projecting into the heart cavities. However, they can also affect other parts of the body, involving both smooth and striated muscles.
While most rhabdomyomas are benign, some may spread and become metastatic, forming secondary tumours in distant sites such as the uterus, bladder, prostate, oesophagus, digestive tract, and kidneys. These mixed tumours are likely to be malignant and may grow to large sizes. In the prostate, for example, they can obstruct the bladder and invade the adjacent pelvic tissue.
Rhabdomyosarcomas, on the other hand, are malignant tumours that arise in the skeletal muscles. They are often found in the leg or arm muscles and may recur even after amputation of the affected limb. These tumours typically appear as slowly growing masses in individuals in their fifth or sixth decade of life and often go undetected for 10 or more years.
It is important to note that any suspected cancerous growth should be promptly evaluated and biopsied for further treatment considerations. Additionally, any sprain or hematoma lasting longer than six weeks warrants additional medical scrutiny to rule out the possibility of a soft tissue tumour.

Soft tissue sarcomas: rare cancerous tumours in muscles, tendons and fat cells
Soft tissue sarcomas are rare cancerous tumours that develop in the tissues supporting and surrounding bones and organs. They can emerge in muscles, tendons, fat cells, nerves, fibrous tissues, blood vessels, or deep skin tissues. Soft tissue sarcomas usually appear in the arms, legs, chest, and back of the belly, but they can develop anywhere in the body.
There are over 50 different types of soft tissue sarcomas, and they can be fast-growing or slow-growing. Some types of soft tissue sarcomas include clear cell sarcoma, desmoplastic small round cell tumours, epithelioid sarcoma, fibromyxoid sarcoma, gastrointestinal stromal tumours, Kaposi sarcoma, leiomyosarcoma, liposarcoma, malignant mesenchymoma, and undifferentiated pleomorphic sarcoma.
The emergence of a soft tissue sarcoma is typically indicated by the appearance of a lump or bump, which may be painless. Other symptoms include a lump that starts to hurt, worsening belly pain, blood in stool, nausea and vomiting, and unexplained weight loss. It is important to note that many soft tissue sarcoma symptoms are similar to less serious conditions. Therefore, it is crucial to consult a healthcare provider for an accurate diagnosis and treatment plan.
While there is no known way to prevent soft tissue sarcoma, early detection can improve treatment outcomes. If you notice any unusual lumps or experience concerning symptoms, it is essential to seek medical advice promptly.

Frequently asked questions
A muscle tumour is an abnormal tissue growth located in or originating from muscle tissue. Tumours may either arise in muscle tissue or spread to it.
The three major types of muscle tumours are leiomyomas, rhabdomyomas, and rhabdomyosarcomas. Leiomyomas are benign tumours of smooth muscles, while rhabdomyomas are usually benign tumours of striated (striped) muscles. Rhabdomyosarcomas are malignant tumours that arise in the skeletal muscles.
Muscle tumours can emerge as a lump or bump slowly or quickly in any part of the body. They are usually painless, causing discomfort only when they compress a nerve or irritate other tissues.
The treatment for muscle tumours depends on the size and location of the tumour. Surgery is the best option, and radiation therapy can be used around the time of surgery to prevent the tumour from growing back. Chemotherapy is used when the tumours are large or when the cancer cells have spread to other parts of the body.
