Clinical Expertise

General diagnostic pediatric pathology with a special interest in:
  • Childhood histiocytoses
  • Pediatric transplantation pathology
  • Pathology informatics

Research Interests

Dr. Picarsic's main academic interest is centered around the pathobiology of histiocytic neoplasms, a rare group of white blood cell disorders that affects both pediatric and adult patients. She leads a busy histiocytic consult service with regional, national, and international case referrals. She has authored numerous manuscripts, abstracts, book chapters, and invited reviews on the topic. She is the North American pathology study reviewer for the International Rare Histiocytic Disorders Registry (IRHDR), which is sponsored by the Histiocyte Society, the international multidisciplinary scientific group on this rare group of disorders. She also serves on both the Scientific Committee and Rare Histiocytic Disorders Committee for the Histiocyte Society. Dr. Picarsic is also involved in a number of collaborative histiocytic research projects with other academic experts in the field. In addition to her diagnostic work on pediatric transplant pathology, Dr. Picarsic has also participated in studies investigating post-transplant lymphoproliferative disorders (PTLD) along with a recent study correlating clinical parameters and outcomes with markers of end-stage fibrosis in pediatric heart transplant patients using novel digital pathology techniques, in collaboration with Dr. Demetris and Dr. Feingold.
