CD117 (c-kit) is a type III receptor tyrosine kinase encoded by the KIT gene. Deregulation of expression and mutations in the gene are implicated in various tumors. Reports of CD117 expression in phyllodes tumors have been controversial. We aim to investigate the protein expression of CD117 and
Mammary phyllodes tumors are uncommon stromal neoplasms, and are divided into benign, borderline and malignant groups basing on histologic criteria. While benign phyllodes tumors may recur, borderline phyllodes tumors show higher propensity to recur locally and rarely metastasize, and malignant
The CD117 protein is a tyrosine-kinase receptor encoded by the c-kit gene that frequently bears activating mutations in gastrointestinal tumors. Conflicting findings regarding CD117 expression in other stromal tumors, including phyllodes tumors (PTs), have been reported in the literature. The
Prostate cancer is a leading cause of cancer-related death in males worldwide. Indeed, advanced and metastatic disease characterized by androgen resistance and often associated with neuroendocrine (NE) differentiation remains incurable. Using the spontaneous prostate cancer TRAMP model, we have
The expression of c-kit, a protooncogene tyrosine kinase receptor (CD117), in phyllodes tumors of the breast has been the subject of recent investigations. We examined stromal c-kit expression by immunohistochemistry in 68 cases comprising fibroadenomas, fibroadenomas with cellular stroma, and
OBJECTIVE
The c-kit gene which codes transmembrane tyrosine kinase receptor protein plays an important role in several types of normal and/or neoplastic human tissues. We examined the expression patterns of c-kit protein in proliferative lesions of human breast tissues in both sexes.
