c-Kit proto-oncogene expression in endometrial hyperplasia and endometrial cancer.
Summary of "c-Kit proto-oncogene expression in endometrial hyperplasia and endometrial cancer."
To evaluate the expression of c-kit (CD117) in endometrial hyperplasia and endometrial cancer.
Expression of c-kit in 10 normal endometrium, 18 simple endometrial hyperplasia, 16 complex endometrial hyperplasia (10 cases with atypia and 6 cases without atypia), and 6 endometrial cancer were investigated by immunohistochemistry.
c-Kit expression decreased as the lesion progressed to endometrial cancer. Immunostaining was mostly focal and weak in the normal endometrium and was mostly diffuse and strong in the simple and complex endometrial hyperplasia.
Simple and complex hyperplastic endometrial tissues express diffuse cytoplasmic staining for c-kit and the expression decreases with the progression of the lesion.

Medical and Biotech [MESH] Definitions
Benign proliferation of the ENDOMETRIUM in the UTERUS. Endometrial hyperplasia is classified by its cytology and glandular tissue. There are simple, complex (adenomatous without atypia), and atypical hyperplasia representing also the ascending risk of becoming malignant.
Endometrial Stromal Tumors
Neoplasms of the endometrial stroma that sometimes involve the MYOMETRIUM. These tumors contain cells that may closely or remotely resemble the normal stromal cells. Endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (SARCOMA, ENDOMETRIAL STROMAL).
Sarcoma, Endometrial Stromal
A highly malignant subset of neoplasms arising from the endometrial stroma. Tumors in this group infiltrate the stroma with a wide range of atypia cells and numerous mitoses. They are capable of widespread metastases (NEOPLASM METASTASIS).
Hamartoma Syndrome, Multiple
A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
Proto-oncogene Proteins C-fes
Proto-oncogene proteins fes are protein-tyrosine kinases with a central SH2 DOMAIN. It has been implicated in SIGNAL TRANSDUCTION PATHWAYS for CELL DIFFERENTIATION of a variety of cell types including MYELOID PROGENITOR CELLS. Fes proto-oncogene proteins also bind TUBULIN and promote MICROTUBULE assembly.
