A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. [1] The word is from leio- 'smooth' myo- 'muscle' and sarcoma 'tumor of connective tissue'. The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
Chronic pain is an issue for as many as 63% of patients and may be debilitating and lead to reliance on pain medication. [ 25 ] [ 18 ] Pressure on vital organs or deformity may occur. [ 25 ] [ 15 ] Rarely, amputation may be necessary due to injury caused by the tumor or its treatments.
The diagnosis is made either by testing of the fumarate hydratase activity in cultured skin fibroblasts or lymphoblastoid cells and demonstrating reduced activity (≤60%) or by molecular genetic testing. [3] Special histologic features of fibroids may allow an early diagnosis in absence of other symptoms. [4]
Bone pain affects almost 70% of people with multiple myeloma and is one of the most common symptoms. [2]: 653 [23] Myeloma bone pain usually involves the spine and ribs and worsens with activity. Persistent, localized pain may indicate a pathological bone fracture. Involvement of the vertebrae may lead to spinal cord compression or kyphosis.
A myoma is a type of tumor that involves muscle cells. [1] There are two main types of myoma: Leiomyomas which occur in smooth muscle. [1] They most commonly occur as uterine fibroids, but may also form in other locations. Rhabdomyomas which occur in striated muscle. [1] [2] [3] They are rare tumors, occur in childhood and often become malignant.
In most cases, pain in the affected area or region is most common. For vaginal leiomyoma, vaginal bleeding and pain may occur. Uterine leiomyoma may exhibit pain in the area as well as painful bowel movement and/or sexual intercourse. Nipple pain, enlargement, and tenderness can be a symptom of nipple-areolar leiomyomas.

Pain is the most obvious symptom of angioleiomyomas. Wind and cold exposure can set off paroxysmal episodes of pain. It is believed to be caused by smooth muscle contractions that are active and cause localized ischemia. It seems that rest is a relieving aspect. [4]
