Smooth Muscle Tumors of the Uterus Pathology
The diagnosis of uterine leiomyosarcoma is usually straightforward since most clinically malignant smooth muscle tumors of the uterus show the microscopic constellation of hypercellularity, severe nuclear atypia, and high mitotic rate generally exceeding 15 mitotic figures per 10 high-power-fields (MF/10 HPF). Frequently, one or more supportive clinicopathologic features such as perior postmeno...
متن کاملDiagnostic Value of Proliferatin Index Including MIB1 and Argyrophilic Nucleolar Organizer Regions Proteins in Uterine Smooth Muscle Tumors
Background and Objectives: Uterine smooth muscle tumors are the most common human neoplasm .They are divided clinically as benign and malignant but there is another group of lesions which is difficult to place in these two categories ,so-called smooth muscle tumors of uncertain malignant potential (STUMP) and differentiation of these tumors on the basis of H&E staining is impossible . Th...
متن کاملImmunohistochemical analysis of p16 expression in uterine smooth muscle tumors.
The expression of p16 as a tumor suppressor protein was evaluated in a retrospective analysis of paraffin-embedded tissue specimens of leiomyosarcoma (LMS), leiomyoma (LM) and normal myometrium. In this study, we investigated by immunohistochemistry p16 expression in 15 LMSs, 15 LMs and ten normal myometrium. Strong expression of p16 was found in 12 of the 15 LMSs and in three cases weak expres...
متن کاملUterine smooth-muscle tumors of uncertain malignant potential.
OBJECTIVE To determine whether tumors meeting the criteria of Hendrickson and Kempson for uterine smooth-muscle tumors of uncertain malignant potential have a natural history different from those of leiomyomas and leiomyosarcomas. METHODS Tumors with five to ten mitoses per ten high-power fields and with mild or moderate cellular atypia were classified as tumors of uncertain malignant potenti...
متن کاملTransgelin, a Novel Marker of Smooth Muscle Differentiation, Effectively Distinguishes Endometrial Stromal Tumors from Uterine Smooth Muscle Tumors.
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...
