What is the role of matrix metalloproteinase-2 in placenta percreta?

Aim: This study compared the placental expression of the matrix metalloproteinase-2 (MMP-2) enzyme, which is thought to play a key role in the penetration of trophoblastic cells, in third-trimester placenta percreta (PP) patients with that of women with normal pregnancies.

Methods: Twenty-five pregnant subjects who underwent cesarean section due to PP and 25 term pregnant subjects who underwent cesarean section for obstetric reasons were included in the study. Demographic data, pathology reports, and histopathological samples were examined.

Comparison of clinicopathological parameters with FoxM1 expression in renal cell carcinoma.

Aim: To investigate the relationships between expression of forkhead box M1 (FoxM1) and clinicopathologic parameters and Ki-67 expression in patients with renal cell carcinoma (RCC).

Materials And Methods: A total of 67 cases of RCC including 47 cases of clear cell RCC (ccRCC), five cases of papillary RCC (pRCC), eight cases of chromophobe RCC (chRCC), four cases of unclassified (with sarcomatoid pattern) RCC (sRCC), and three cases of multilocular RCC (mRCC) were included to this study. The expression of FoxM1 protein was assessed in 67 samples of RCC using immunohistochemical methods and the relationship between the expression levels of FoxM1 with clinicopathological characteristics and Ki-67 expression of RCC patients.

The relationship of mast cells and angiogenesis with prognosis in renal cell carcinoma.

Objective: To evaluate the effects of mast cell count and angiogenesis on the prognosis of renal cell carcinoma.

Methods: The retrospective study was conducted at the Harran University, Sanliurfa, Turkey, and included 64 cases with diagnosis of renal cell carcinoma between 2002 and 2012. Immunohistochemical analysis was performed on paraffin sections using the standard streptavidin-biotin immunoperoxidase method.

A case of renal synovial sarcoma treated with adjuvant ifosfamide and doxorubicin.

Primary renal synovial sarcomas (SS) are rare tumors of the kidney. Faria et al first described primary renal synovial sarcoma in 1999 (Mod Pathol 12:94A). In this paper we present a primary renal synovial sarcoma case and review the 41 primary renal synovial sarcoma cases reported to date.
