conclusions preoperative diagnosis of spermatic cord leiomyosarcma is difficult and commonly made by histological examination and immunochemical staining. case presentation here we reported a 75-year-old man who presented with a painless lump in the right hemiscrotum. a right radical orchiectomy was performed. histopathology confirmed a neoplastic tissue with mesenchymal origin in spermatic cor...

Radiol Bras. 2016 Set/Out;49(5):340–346 344 http://dx.doi.org/10.1590/0100-3984.2014.0136 Leiomyoma is a benign tumor composed of smooth muscle tissue and is considered one of the most common mesenchymal neoplasms in the gastrointestinal tract and uterus. Leiomyoma of the breast originates from the stroma of the gland and is extremely rare. Mammography and ultrasound studies are commonly used a...

BACKGROUND Atypical uterine leiomyomas show benign behavior. However, the distinction between leiomyomas and leiomyosarcomas may at times be problematic. We report a rare case of atypical uterine leiomyoma. We try to investigate potential immunohistochemical parameters that could be essential to distinguish cases of malignant smooth muscle tumors and those of uncertain or borderline histology. ...

Uterine smooth muscle tumors of uncertain malignant potential (STUMPs) represent a heterogeneous group that cannot be histologically diagnosed as unequivocally benign or malignant. For this reason, many authors are working to obtain better definition diagnostic and prognostic criteria. In work, we analyzed the genomic epigenomic profile uterine (USMTs) in order find similarities differences bet...
