Muscle tumors of the soft tissue are uncommon. It is difficult to establish their prevalence, but it is estimated that benign muscle tumors make up less than 2% of all benign soft tissue tumors (), while rhabdomyosarcoma and leiomyosarcoma account for approximately 2% to 12% and 8% to 9%, respectively, of all classified soft tissue sarcomas (2, 3, 4).

Oct 9, 2014 A recent Memorial Sloan Kettering study suggests new ways to control malignant peripheral nerve sheath tumors (MPNSTs), a rare, aggressive

However, adjuvant chemotherapy might be an appropriate therapeutic modality. Smooth muscle tumor of uncertain malignant potential, abbreviated STUMP, is an uncommon tumor of the uterine smooth muscle that may behave like a benign tumor or a cancerous tumor. This tumor should not be confused with the prostatic stromal tumor of uncertain malignant potential which may be abbreviated the same way (STUMP). 1980-07-01 · On microscopy the tumor consisted of interlacing smooth muscle bundles.

Malignant tumor of smooth muscle

Liposarcomas are malignant tumors of fat tissue. Leiomyosarcoma are malignant tumors of smooth muscle. They may be cutaneous and presumably arise from the arrector pilorum muscle, or subcutaneous, where they are believed to arise from vascular smooth muscle. Cutaneous leiomyosarcomas frequently reoccur following excision, but rarely metastasize. Pleomorphic or epithelioid cases may require desmin or caldesmon reactivity to support smooth muscle differentiation Any one of the following is sufficient to diagnose a smooth muscle tumor as malignant for the stated sites Cytologic pleomorphism or atypia A uterine leiomyosarcoma is a rare malignant (cancerous) tumor that arises from the smooth muscle lining the walls of the uterus (myometrium). There are essentially two types of muscles in the body: voluntary and involuntary.

While leiomyosarcoma has been studied at length, smooth muscle tumors of uncertain malignant potential (STUMPs) still have ambiguous and unresolved issues, with a risk of relapse and evolution largely undefined. Cutaneous leiomyomas (leiomyoma cutis) are the most common group of benign smooth muscle tumors, with two types. Those arising from the pilar arrector muscles of the skin are often multiple and associated with significant pain. Purpose.
