Benign smooth muscle or skeletal muscle tumours are usually caused by genetic mutations. They can also be caused by certain environmental factors, such as exposure to certain chemicals, radiation, or certain viruses.
Diagnosis is usually made through physical examination and imaging studies, such as an MRI or CT scan. Biopsy of the tumour may be necessary to confirm the diagnosis.
Differential diagnosis of benign smooth muscle or skeletal muscle tumours includes other benign and malignant tumours, metastatic carcinomas, inflammatory conditions, and infections.
Treatment options include surgical excision, radiation therapy, and chemotherapy. If the tumour is small and asymptomatic, it may not need to be treated.
Benign smooth muscle or skeletal muscle tumours usually have a good prognosis, with a low risk of recurrence and metastasis. However, the prognosis depends on the size and location of the tumour, as well as the type of treatment that is used.
