Diagnostic Utility of Microphthalmia Transcription Factor in Malignant Melanoma and Other Tumors

Abstract excerpt

The diagnosis of malignant melanoma is sometimes challenging. Immunohistochemistry for specific markers of melanocytic differentiation such as HMB-45 and Melan-A can be very valuable in proving melanocytic differentiation in poorly differentiated or spindled forms of melanoma. Microphthalmia-associated transcription factor (MiTF) is the most recently described and the only nuclear melanocytic marker. This article...
