Muscle pain can be a symptom of melanoma, although this is rare. The vast majority of melanoma cases appear as visible lesions on the skin. However, in some cases, melanoma can spread to the muscles, causing pain. This is known as skeletal muscle metastasis, and it occurs when melanoma cells metastasize to the skeletal muscle, resulting in painful and tender masses. If you experience persistent muscle pain or other concerning symptoms, it is important to consult a doctor for a definitive diagnosis.

What You'll Learn
Muscle metastases from melanoma are rare
There have been a few reported cases of malignant melanoma metastasizing to skeletal muscle. In one case, a 43-year-old man with no history of skin surgery presented with progressively worsening dyspnea and a painful swelling in the right buttock. A computed tomography scan revealed a tissue mass at the expense of the gluteus maximus muscle, which was later confirmed to be a stage IV malignant melanoma with lymph node metastases and extension to the right gluteus maximus.
Another case involved a 41-year-old female who presented with a pigmented nodule on her right forearm and a painless lump in her right armpit. A biopsy confirmed malignant melanoma with metastasis to the skeletal muscle. In yet another case, a young female patient presented with malignant melanoma metastasis in the thigh musculature.
While muscle metastases from melanoma are uncommon, they can occur and cause pain. Therefore, it is essential to be vigilant and seek medical advice if you experience persistent muscle pain or other concerning symptoms.
Although muscle metastases from melanoma are rare, it is important to note that melanoma can spread to other areas of the body, including the skin, lymph nodes, lungs, liver, brain, bone, and intestine. The symptoms of advanced melanoma depend on the location of the metastasis, and early detection and intervention are crucial for successful treatment.

Melanoma can cause bone pain
Melanoma is a particularly aggressive form of skin cancer that can affect various parts of the body beyond the primary tumour site. It is usually discovered from an irregular skin patch or a modification of a pre-existing patch. While it rarely spreads to the muscles, it can spread to the bones, causing bone pain.
Melanoma can spread to the bones
When melanoma advances, it can spread to the bones, causing severe and hard-to-treat pain. Bone metastases often occur at a late stage of advancing melanoma. In some cases, a metastasis in the bones may be palpable, or capable of being felt, especially in people with thin skin and little body fat.
If melanoma spreads to the bones of the spine, it can put pressure on the nerves of the spinal cord, a condition known as malignant spinal cord compression (MSCC). Symptoms of MSCC include back or neck pain, which might feel like a band around the chest or tummy. It is important to seek immediate medical attention if you experience symptoms of spinal cord compression, as you may require urgent surgery or radiotherapy.
Melanoma can cause muscle pain, but it is rare
While muscle metastases from melanoma are rare, they can occur, and when they do, they often manifest as a painful mass. The paravertebral and proximal limb muscles are the most affected, with the thigh muscles, iliopsoas, and paraspinous muscles being the most frequent sites of clinical involvement.
In some cases, muscle metastases from melanoma may be misdiagnosed as a lipoma or soft tissue sarcoma, which has different treatment and prognosis. Therefore, it is important to seek medical attention for persistent pain, lumps, or bumps, and to advocate for yourself if a diagnosis seems inconsistent with your symptoms.
General symptoms of advanced melanoma
In addition to bone pain and muscle pain, advanced melanoma can cause various other symptoms, depending on where the cancer has spread. For example, if melanoma spreads to the liver, it can cause pain and tenderness in the mid-section. If it spreads to the lungs, patients may experience chronic chest pain, shortness of breath, or a persistent cough. Melanoma that has spread to the brain may cause persistent headaches, memory problems, vision issues, or even personality changes.
It is important to remember that the presence of any of these symptoms does not necessarily indicate advanced cancer, as they can also be caused by other conditions. However, if you are experiencing any concerning symptoms, it is crucial to consult your doctor or specialist nurse, especially if the symptoms persist for more than a few days.

Muscle pain may be a symptom of advanced melanoma
Melanoma is a type of skin cancer that can spread to other areas of the skin or soft tissues, which include muscles, nerves, fat, and blood vessels. It can also spread to other parts of the body, including the liver, lungs, bones, and brain. When melanoma spreads to the bones, it can cause severe and hard-to-treat pain. Bone metastases often occur at a late stage of advancing melanoma. Metastases to the skeletal muscle are frequently painful.
There have been a few reported cases of malignant melanoma metastasizing to the skeletal muscle. In one case, a 43-year-old man presented with dyspnea and was found to have melanoma with infiltration of the gluteus maximus muscle. Another case reported a young female patient with a pigmented lesion on her forearm and a painless lump in her right axilla, which was diagnosed as malignant melanoma with skeletal muscle metastasis.
It is important to note that muscle pain can be caused by various other conditions and does not always indicate melanoma. However, if you experience persistent muscle pain or other concerning symptoms, it is crucial to consult a doctor for a definitive diagnosis. Early detection and intervention are essential in the treatment of melanoma.

Melanoma can spread to the lungs, causing chronic chest pain
Melanoma is a type of skin cancer that develops when the cells that give skin its colour (called melanocytes) start to grow out of control. When cancer cells spread, it is called metastasis or metastatic melanoma. Melanoma can spread from the original site on the skin and form a tumour in any organ or body tissue.
Metastatic melanoma is a disease that occurs when the cancerous cells from the original tumour (primary tumour) get loose, spread by travelling through the lymph or blood circulation, and start a new tumour (metastatic tumour) somewhere else. Melanoma can spread to other areas of the skin or to soft tissue, which includes muscles, nerves, fat, and blood vessels.
Muscle metastases are rare and solitary forms occur in 0.8% of cases. However, melanoma can spread to the lungs, causing chronic chest pain. A persistent cough, recurring chest infections, and shortness of breath can be signs that melanoma has spread to the lungs. Melanoma tumours in the lungs can also cause changes in calcium levels, which may result in sleepiness, confusion, or changes in bowel habits.
If you notice any of these symptoms, it is important to consult a doctor right away.

Melanoma can spread to the liver, causing pain in the mid-section
Melanoma is a type of skin cancer that develops when the cells that give skin its colour (called melanocytes) start to grow out of control. When these cancer cells spread, it is called metastasis or metastatic melanoma. Metastatic melanoma is a disease that occurs when cancerous cells from the original tumour spread by travelling through the lymph or blood circulation and start a new tumour somewhere else.
Melanoma can spread from the skin to other organs or body tissues, but it is most likely to spread to the lymph nodes, liver, brain, lungs, and less commonly, the bones. When melanoma spreads to the bones, it can cause bone pain.
The liver is a common site for metastatic melanoma. Symptoms of melanoma that has spread to the liver include an enlarged, hard, or tender liver and pain in the upper right area of the abdomen, just below the ribs. This pain in the mid-section can be caused by the secondary cancer pressing on the liver and blocking or partially blocking it, which is called bowel obstruction. Bowel obstruction is an emergency and can cause cramping abdominal pain that comes in waves, alongside nausea, bloating, and an inability to pass wind or have a bowel movement.
Muscle metastases from melanoma are rare, occurring in only 0.8% of cases. However, when melanoma does spread to the muscles, it often manifests as a palpable and painful mass.

Frequently asked questions
Although rare, melanoma can cause muscle pain if it spreads to the muscles.
The symptoms of advanced melanoma depend on where the cancer has spread to. Some people may not experience any symptoms at all. General symptoms may include swollen lymph nodes, weight loss, loss of appetite, and flu-like symptoms such as fever and chills.
The most common sites of melanoma metastasis are the skin, subcutaneous tissue, and lymph nodes, followed by the lungs, liver, brain, bone, and intestine.
Treatment options for metastatic melanoma include surgery, radiotherapy, chemotherapy, and hyperthermia. The treatment chosen depends on factors such as the number and site of metastatic lesions, the patient's age and health, previous treatments, and the patient's wishes.
Melanoma usually presents as an irregular skin patch or a modification of a pre-existing mole. If you notice any persistent pain, lumps, bumps, or spots that are changing in size, colour, or shape, consult your doctor immediately.
