Overview
Leiomyosarcoma is a type of sarcoma which is a neoplasm of smooth muscle. (When benign, it is called a leiomyoma.) Smooth muscle cells make up the involuntary muscles, which are found in most parts of the body: in uterus, stomach and intestines, walls of all blood vessels, and skin. Leiomyosarcoma is a very rare cancer. It makes up 7% of soft tissue sarcomas.[1] The symptoms of a leiomyosarcoma vary depending upon the exact location, size, and spread of the tumor. A leiomyosarcoma, especially in the early stages, may not be associated with any obvious symptoms (asymptomatic). General symptoms associated with cancer may occur including fatigue, fever, weight loss, a general feeling of ill health (malaise), and nausea and vomiting.
Pain may occur in the affected area but is uncommon. Swelling usually occurs and a mass is commonly detected. Additional symptoms are specific to the exact location of the tumor. The tumors may cause bleeding in the gastrointestinal tract and cause black, tarry, foul-smelling stools (melena), or vomiting of blood (hematemesis) or abdominal discomforts). A leiomyosarcoma of the uterus may cause abnormal bleeding from the uterus into and the vagina, with abnormal vaginal discharge, and a change in bladder or bowel habits.
