Leiomyosarcoma (Gr. smooth muscle connective tissue tumor) aka LMS is a malignant (cancer) smooth muscle tumor. (When such a neoplasm is benign it is a leiomyoma.) Leiomyosarcoma is a relatively rare form of cancer and accounts for between 5–10% of soft tissue sarcomas which are in themselves relatively rare. Leiomyosarcomas can be very unpredictable. They can remain dormant for long periods of time and recur after years.
