Research

Dr. Hoang's research interests focus on the role of immunohistochemistry as ancillary diagnostic tools in pathology and as predictive/prognostic markers in rare cutaneous tumors. Several of her studies have highlighted the role of immunostains in distinguishing benign versus malignant adnexal neoplasms, porocarcinoma versus squamous cell carcinoma, and primary adnexal carcinomas versus cutaneous metastases. Validation studies have confirmed the role of BRAFV600E, BAP1, and ROS1 immunostains as sensitive, specific, and cost-effective screening tests in detecting underlying molecular abnormalities. Recent works from an international collaborative effort with investigators from 10 clinical centers in the U.S., Spain, Poland, and Taiwan, have highlighted the prognostic role of gene mutation (NRAS, KIT, BRAF, SF3B1), some biomarkers and immune infiltrates in mucosal melanomas, desmoplastic melanomas and Merkel cell carcinomas.
