INTRODUCTION Smooth muscle tumors of uncertain malignant potential represent a histologically heterogeneous group of uterine smooth muscle tumors that cannot be diagnosed as either benign or malignant. Smooth muscle tumors of uncertain malignant potential are usually clinically benign, but should be considered tumors of low malignant potential because they can occasionally recur or metastasize ...
Leiomyosarcoma is a malignant smooth muscle tumor. It the second most common primary retroperitoneal tumor behind liposarcoma. The léiomyosarcoma represents 11% of all tumors. age discovery between 40 and 60 years.
•Clinical experience with smooth muscle tumors of the vulva is limited.•Some tumors present ambiguous histological features concerning for malignancy.•These include infiltration, mitotic activity, size, atypia and tumor cell necrosis.•A case of smooth muscle tumor of the vulva with cellular atypia is presented.•"Smooth Muscle Tumor of Uncertain Malignant Potential" of the vulva is advocated.
Leiomyomas are benign soft tissue tumors of smooth muscle origin, most found in the uterus [1-2]. Extra uterine leiomyomas presenting as an abdominal mass is a rare issue and often diagnostic challenge [3].
Ovarian smooth muscle tumors are a very rare type of ovarian tumor. In this paper, we report the case of a 62-year-old woman who had a huge smooth muscle tumor of the right ovary. The values of all the serum tumor markers were within normal limit. The tumor measured 25 cm in diameter and weighed 6,200 g. Histological examination revealed that coagulative cellular atypia was moderate to severe, ...
Colorectal mesenchymal tumors are rare. Therefore, distinguishing between gastrointestinal stromal (GIST) and smooth muscle tumors is important. This study aimed to delineate the immunophenotype and prognostic factors of 75 colorectal mesenchymal tumors. Fifty-three GIST and 22 smooth muscle tumor specimens were included from 1986 to 2007. Forty of 53 GIST were initially diagnosed as smooth mus...
introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...
objective(s): thyroid hormones play an essential role in fetal growth and maternal hypo-thyroidism which leads to cardiovascular deficiency in their offspring. considering this, we intended to investigate the impact of gestational hypothyroidism on offspring vascular contractibility and possible underlying mechanisms. materials and methods: hypothyroidism was induced in female rats by administ...
saffron, crocus sativus l. (c. sativus) is rich in carotenoids and used in traditional medicine for treatment of various conditions such as coughs, stomach disorders, amenorrhea, asthma and cardiovascular disorders. these therapeutic effects of the plant are suggested to be due to its relaxant effect on smooth muscles. the effect of c. sativus and its constituents on different smooth muscles an...
Differentiation between endometrial stromal sarcomas (ESSs) and smooth muscle tumors of the uterus can be challenging. Transgelin, a 22 kDa actin-binding protein has recently been shown to be a smooth muscle specific marker. The goal of this study was to determine whether transgelin could accurately distinguish ESSs from smooth muscle tumors. The expression of transgelin, CD10 and smooth muscle...
