Dr. Ronnie Abraham was recruited to join Saint John’s Pathology department’s growing Dermatopathology service in 2020, following several years of clinical practice, Dermatopathology training at Memorial Sloan-Kettering Cancer Center, and Pathology residency at the University of Pennsylvania. He is board certified in Dermatopathology as well as Anatomic and Clinical Pathology. Dr. Abraham has published several original research articles in the field of Dermatopathology and coauthors a skin pathology book chapter with Dr. David Elder in Rubin’s Pathology. His diagnostic and research interests include melanoma, difficult/borderline melanocytic lesions and cutaneous lymphomas.
Along with his expertise in dermatopathology, Dr. Abraham has clinical interests in molecular pathology as well as clinical and pathology informatics, and brings broad new expertise to Saint John’s and its Cancer Institute.
