Review of 36 cases of colonic leiomyosarcoma in the literature and our case demonstrate that most patients complain of an abdominal mass and a change in bowel habits of short duration. No physical finding has prognostic value. The mitotic activity of the tumor is the best index of survival time.

Leiomyosarcoma and Pleomorphic Dermal Sarcoma: Guidelines for Diagnosis and Treatment.
Actas Dermo-Sifiliográficas, 2019There are 3 types of leiomyosarcoma of the skin: dermal, subcutaneous, and metastatic cutaneous. Dermal leiomyosarcoma arises from smooth muscle fibers in arrector pili muscles, genital dartos muscles, and the nipple-areola complex. It is an intermediate-

Clinical outcomes of surgical resection for leiomyosarcoma of the inferior vena cava.
Annals of Vascular Surgery, 2019BACKGROUND Leiomyosarcoma of the inferior vena cava (IVC) is a rare mesenchymal tumor with poor prognosis. Surgical resection is currently the only potential curative treatment.

In adults, rectal leiomyosarcoma is uncommon, and anal leiomyosarcoma is even more rare. We report one patient with anal leiomyosarcoma and one patient with a biphasic clinical history, with three occurrences of perineal leiomyosarcomas after surgically resected rectal leiomyoma. We discuss the characteristics of these rare entities based upon a review

Leiomyosarcoma of the skin is a rare tumor that cannot be diagnosed clinically because its gross appearance is nonspecific. The primary skin tumor usually appears as a solitary nodule. It may arise de novo in the dermis or in the subcutaneous tissue, or as a metastatic lesion from an internal neoplasm.

Histopathology, 1985
A series of 13 myxoid leiomyosarcomas (LS) is presented. Seven were from genital and six from extragenital sites and most tumours were large. The myxoid matrix in some tumours separated individual tumour cells; occasionally the myxoid areas were trabecular in shape, resulting in a plexiform tumour pattern; in other tumours there were many closely ...

Leiomyosarcoma of the rectum is a rare malignant tumor with an incidence of 0.1%, occurring more frequently in men than in women and in the fifth, sixth, and seventh decades of life. Microscopically it has a characteristic appearance of interlaced bundles of spindle cells with abundant mitosis and cellular pleomorphism.

Leiomyosarcomas are rare, aggressive tumors, which exhibit a poor prognosis regardless of stage. Pre-operative diagnosis can be difficult as leiomyosarcoma can mimic features of the more common, benign uterine leiomyoma.

Uterine Leiomyosarcoma: Can MRI Differentiate Leiomyosarcoma From Benign Leiomyoma Before Treatment?
AJR. American journal of roentgenology, 2018OBJECTIVE The purpose of this article is to provide background on the epidemiologic, clinical, and economic impact of uterine leiomyomas, summarize the concerns associated with treating women with potential occult leiomyosarcomas (LMSs), and review the ...
