Dr. Somma joined the Department of Pathology at LSUHSC in January 2018 as an Associate Professor of Clinical Pathology and Director of Cytopathology at University Medical Center-New Orleans. Prior to this, he was teaching and practicing pathology at SUNY Downstate Medical Center in Brooklyn, New York where he also served as Director of Cytopathology and Director of their ACGME accredited Pathology Residency Training Program.

Dr. Somma supervises and instructs medical students, resident physicians, fellows, and occasionally other graduate students in a variety of settings ranging from individually to small groups in the classroom to large formal lectures. Most of his teaching, however, occurs daily with resident physicians, where he supervises and instructs them in various aspects of pathology including microscopic diagnosis, medical billing, laboratory and quality management, and informatics.


Clinical Interests

Clinical and research interests overlap and span several areas of cytopathology, especially cytopathology of the pancreas and of the thyroid. He is adept in the performance of ultrasound-guided fine needle biopsies, particularly of the head and neck and of lymphadenopathy.


Research Interests

He has studied the use of digital pathology with artificial intelligence to improve diagnostic accuracy in cytopathology. In thyroid fine needle biopsy, he has investigated the problem of indeterminate nodules, most recently with a binary logistic regression model that uses a combination of microscopic, clinical and radiologic findings to predict malignancy risk.

Another area of research interest is the use of immunochemistry to diagnose and prognosticate malignancies. He has contributed to the development of a pY p27 biomarker immunoassay to predict responsiveness to CDK4 inhibitor therapy, which shows great promise for utilization in breast, ovarian and potentially other cancer patients as well. Additionally, he collaborated on a study of NP-ALT, a liposomal:peptide drug, that directly targets p27 and appears highly effective in cell cycle blockade.
