Found insideThis book provides the pathologist with detailed morphologic descriptions and diagnostic guidance in recognizing these neoplastic mimics as they occur in the soft tissues and bones. We examined the immunohistochemical expression of KIT in 70 resected thymic epithelial tumors (thymomas, 50; thymic carcinomas, 20) that had been reclassified on the basis of the World Health Organization histologic classification system. 2.1. The expression of KIT (CD117) in thymic epithelial tumors was investigated in order to evaluate its usefulness as a marker supporting differential diagnosis and choice of therapy. We also compared the expression of KIT and CD5 in 20 thymic carcinomas with their expression in 20 resected pulmonary squamous cell carcinomas that were spreading directly into the mediastinum. e if PAX-8, CD5, and CD117 can differentiate thymic carcinoma from poorly differentiated lung carcinoma.

Although immunoreactive CD5 has been reported 5 6 7 as a useful marker for primary thymic squamous cell carcinoma in routine surgical pathology, it is still necessary to identify other diagnostic markers to make this differential diagnosis more reliable. These markers were identified among many other possible choices because they are cited frequently for use in detecting PCs and for distinguishing between normal and abnormal PCs. Positivity of both markers was correlated with clinicopathological variables. FOIA Mast cells were identified using an antibody to CD117, the CKIT receptor found on the surface of all mast cells. 2 Most (94 of 136 cases; 69%) were International Society of Urological Pathology (ISUP) nucleolar grades 3 or 4.

In at least 1 case (case 21), immunohistochemical analysis for CD34 was performed on the bone marrow and skin lesion and showed blast expression of CD34 in the bone marrow but not in the skin. Hepatocellular carcinoma (HCC) currently ranks as the third most common cause of death. As the primary malignancy of the liver is directly related to an underlying liver condition, its incidence and profile are expected to change soon. Design: Archived cases of thymic (n=13) and poorly differentiated lung (n=15) carcinoma were analyzed for intensity and proportion of expression of PAX-8, CD117, and CD5.
