Muscle tumours, also known as soft tissue tumours, can occur in various parts of the body, including the tendons, muscles, ligaments, cartilage, nerves, blood vessels, fat, and other tissues. They can be either benign or malignant. Benign tumours, such as leiomyomas, are typically slow-growing and do not invade or spread to other body parts, while malignant tumours like rhabdomyosarcomas can grow and spread aggressively. Muscle tumours can affect people of all ages, but certain types, such as skeletal muscle sarcomas, are more prevalent in children and young adults. Diagnosis and treatment options vary depending on the specific type, location, and biological characteristics of the tumour.

Soft tissue tumours can emerge anywhere in the body, including muscles, tendons, ligaments, and nerves
Soft tissue tumours can emerge in any part of the body, including muscles, tendons, ligaments, nerves, cartilage, blood vessels, fat, and other tissues. These tumours are known as soft tissue sarcomas and can be either benign or cancerous. Benign tumours are more frequently discovered than malignant tumours, which are referred to as sarcomas. Malignant tumours grow faster and spread to other body parts, whereas benign tumours stay at the tumour site and do not invade other tissues.
Skeletal muscle sarcomas are a type of soft tissue sarcoma that can form anywhere in the body, although they are most common in the arms and legs. They are classified into four main forms: embryonal rhabdomyosarcoma, alveolar rhabdomyosarcoma, spindle cell/sclerosing rhabdomyosarcoma, and pleomorphic rhabdomyosarcoma. These tumours are further classified into two types: rhabdomyomas, which are usually benign, and rhabdomyosarcomas, which are malignant. Rhabdomyomas are typically found in the heart and are soft, occurring in nodes, flat masses, round clusters, or polyps. On the other hand, rhabdomyosarcomas are usually located in the leg or arm muscles and can recur even after amputation.
Smooth muscle sarcomas can also occur anywhere in the body but are most common in the uterus and abdomen. Leiomyosarcoma is a malignant form of smooth muscle sarcoma, while leiomyoma is a benign tumour that commonly occurs in premenopausal women. Angioleiomyoma is another benign smooth muscle tumour that often occurs near the foot and ankle. It is slow-growing and challenging to diagnose.
The symptoms and diagnostic tests for soft tissue tumours depend on their location in the body. For example, a tumour on the foot or pressing against a nerve could reduce mobility. Tumours in the head and neck area may cause specific symptoms, and diagnostic tests may vary based on the tumour's location. Soft tissue masses are often initially misdiagnosed as muscle sprains or old traumas, leading to delayed diagnoses. It is important to consult a physician if any abnormal lumps or concerning symptoms are present.

Leiomyomas are benign tumours of smooth muscles, most frequently located in the uterus
Leiomyomas are benign tumours composed of smooth muscles and connective tissue. They are most frequently located in the uterus, where they are also known as uterine fibroids. Leiomyomas can also occur in other parts of the body, such as the ovaries, fallopian tubes, bladder, ureters, and intestines. These tumours are usually firm or rubbery in texture and can be easily removed through surgery. While leiomyomas are typically benign, there are rare cases where they may become malignant or cancerous.
Uterine leiomyomas are the most common type of benign mesenchymal tumours, arising from the overgrowth of smooth muscle and connective tissue in the uterus. They are well-circumscribed but non-encapsulated and usually multiple, varying in size and distorting the contour of the uterus. Most leiomyomas do not produce symptoms, but they can cause abnormal bleeding patterns, urinary incontinence due to pressure on the bladder, constipation from pressure on the rectum, and in rare cases, edema or varicosity of the legs if the tumours are extremely large.
Leiomyomas are commonly found in women, with a median age of presentation of 40 years. While most women are asymptomatic, some may experience symptoms such as vaginal bleeding or discharge, lower abdominal or vaginal pain, dyspareunia, frequency, dysuria, urinary retention, or a noticeable vaginal mass. It is important to note that leiomyomas can enlarge during pregnancy and partially involute postpartum.
Although leiomyomas are typically benign, they can cause significant health concerns. For example, they may lead to excessive menstrual bleeding (menorrhagia), often resulting in anaemia and, in some cases, infertility. In extremely rare cases, a form of leiomyoma known as uterine lipoleiomyoma, which consists of a mixture of adipocytes and smooth muscle cells, has been observed to develop into liposarcoma. Additionally, metastatic leiomyoma, a rare complication after surgery to remove the uterus for uterine fibroids, has been reported with the most frequent sites of occurrence being the lungs and pelvis.
While leiomyomas themselves are benign, it is important to monitor them and seek medical advice if any unusual symptoms or changes occur. In some cases, surgical excision may be recommended to remove the tumour and alleviate associated symptoms. Overall, leiomyomas are a common occurrence, particularly in the uterus, and can be managed effectively through proper diagnosis and treatment.

Rhabdomyomas are usually benign tumours of striated muscles, commonly occurring in the heart
Rhabdomyomas are rare, usually benign tumours of striated muscles. They are most commonly found in the heart, with some forms spreading to other parts of the body. When rhabdomyomas occur in the heart, they grow in the wall and may project into the heart cavities. They are often found in patients with tuberous sclerosis, a genetic condition causing multiple tumours, and are typically detected in patients under the age of one.
Rhabdomyomas are soft tumours that may occur in nodes, flat masses, round clusters, or polyps. When found in the heart, they are known as cardiac rhabdomyomas and are typically located in the ventricular walls or on the valves. These tumours can be detected prenatally or in infants using imaging techniques such as ultrasound and magnetic resonance imaging (MRI). If symptomatic, patients may present with heart failure or an arrhythmia, such as ventricular tachycardia or heart block.
While rhabdomyomas are usually benign, some forms can spread to other parts of the body, including the uterus, bladder, prostate, oesophagus, digestive tract, and kidneys. When rhabdomyomas affect other parts of the body beyond the heart, they commonly involve both smooth and striated muscles. These mixed tumours are more likely to be malignant and can grow to significant proportions. For example, tumours in the uterus, vagina, or prostate may be large, polyp-shaped masses that protrude and cause obstruction or invasion of adjacent tissues.
The treatment of rhabdomyomas depends on their location and symptoms. Cardiac rhabdomyomas, especially in asymptomatic cases, can be monitored with routine imaging as they may spontaneously regress. Symptomatic tumours can be treated with resection, and in fetuses, maternal sirolimus administration has been shown to reduce tumour size. For rhabdomyomas in other parts of the body, treatment options may include surgery, radiation, clinical trials, or targeted therapy, depending on the patient's needs.

Rhabdomyosarcoma is a malignant tumour that arises in skeletal muscles, often in the arms or legs
Rhabdomyosarcoma (RMS) is a rare soft tissue cancer that arises in skeletal muscles. It is a malignant tumour that usually affects children and teenagers but can also develop in adults. RMS is often found in the arms or legs, but it can occur anywhere in the body, even in areas without skeletal muscle.
RMS originates from rhabdomyoblasts, cells that typically develop into skeletal muscles. These cells form during embryogenesis, which is why RMS is more common in children. However, it can sometimes occur in adults, with certain subtypes like anaplastic rhabdomyosarcoma primarily affecting adults and rarely occurring in children.
The symptoms of RMS depend on the tumour's location. For example, a tumour in the arm or leg muscle may present as a mass, lump, or swelling that could be painful. Tumours in the abdomen may cause belly pain, constipation, or vomiting, while those in the nasal cavity may lead to nosebleeds or sinus infections.
RMS treatment options vary and may include traditional methods such as surgery and radiation therapy, as well as newer approaches like clinical trials and targeted therapy. While oncologists can treat and sometimes cure RMS, the condition can recur even after amputation of the affected limb. Therefore, early detection and comprehensive treatment plans are crucial for managing this rare cancer effectively.
It is important to note that soft tissue masses can be benign or malignant, and a medical evaluation is necessary to determine their nature. While benign masses are typically round, cancerous growths can be elliptical or elongated. Masses larger than 5 cm carry a higher risk of being malignant and warrant medical attention.

Skeletal muscle sarcomas are typically found in children, but can also occur in adults
Skeletal muscle sarcomas are a type of soft tissue sarcoma that typically affects children but can also occur in adults. Soft tissue sarcomas are cell growths that emerge in muscles, tendons, ligaments, nerves, blood vessels, fat, and other tissues. They can be benign or malignant. While skeletal muscle sarcomas are rare in adults, they can be malignant and spread quickly to other parts of the body when they do occur.
In children, skeletal muscle sarcomas occur mostly in the paratesticular region, followed by the head and neck. Embryonal rhabdomyosarcoma is a common type of skeletal muscle sarcoma that mainly affects children under five years of age and occurs in the head and neck area, bladder, vagina, or near the prostate and testicles. Symptoms of this type of sarcoma include sinusitis, unilateral deafness, urinary retention, and jaundice.
In adults, alveolar rhabdomyosarcoma is a type of skeletal muscle sarcoma that occurs in the large muscles of the trunk, arms, and legs. Pleomorphic rhabdomyosarcoma is a rare subtype that occurs in older adults (60–70 years) in the lower extremities, such as the leg, ankle, and foot. Spindle cell/sclerosing rhabdomyosarcoma is another rare subtype that can affect all age groups, developing mainly in the head and neck of adults.
Diagnosing skeletal muscle sarcomas involves a physical examination, neurological assessment, and diagnostic tests such as MRI, ultrasound, X-rays, and PET scans. Treatment options include surgery, radiation therapy, chemotherapy, clinical trials, and targeted therapy. While limb-sparing surgery is effective in treating over 90% of children with soft tissue sarcomas, amputation may be necessary in rare cases.
