Benjamin Ellezam

Benjamin Ellezam is an Associate Clinical Professor at the University of Montreal's Faculty of Medicine, with appointments in both the Department of Pathology and Cell Biology and the Department of Neuroscience. He is a neuropathologist and researcher at CHU Ste-Justine, where he serves as head of the diagnostic myopathology laboratory, a reference center in Quebec for the analysis of muscle biopsies.

Dr. Ellezam's educational background includes:

• BSc in Biochemistry (minor in Neuroscience) from McGill University (1997)
• PhD in Neurological Sciences from the University of Montreal (2002)
• MD from the University of Montreal (2006)
• DES in Anatomopathology from the University of Montreal (2010)
• Neuropathology Fellowship at MD Anderson Cancer Center/Texas Children's Hospital (2012)

His primary research interests focus on neuropathology, particularly autoimmune myositis and ultrastructural neuropathology. He is the founder and director of the CHU Sainte-Justine biobank on nervous and neuromuscular diseases, which makes hundreds of pediatric brain tumor and muscle biopsy specimens available for research. His work spans multiple disciplines including myopathology, ultrastructural pathology, and the pathology of pediatric brain tumors.

Dr. Ellezam's recent publications demonstrate a strong focus on the intersection of neuropathology, muscle diseases, and pediatric brain tumors. His research often examines the molecular and cellular mechanisms underlying these conditions, with particular attention to autoimmune myositis, genetic myopathies, and the histopathological features of rare neurological disorders. His work has significant implications for diagnostic criteria and potential therapeutic approaches.

Notable scientific contributions include:

• Identifying capillary pathology with prominent basement membrane reduplication as a hallmark feature of scleromyositis
• Research on the pathology of autoimmune myositis
• Studies on genetic myopathies including TNNT1 congenital core-rod myopathy
• Investigations into the molecular mechanisms of pediatric brain tumors

As director of the CHU Sainte-Justine biobank, Dr. Ellezam oversees a critical resource for researchers studying nervous and neuromuscular diseases. His work bridges clinical practice and research, with a focus on translating pathological findings into improved diagnostic approaches and potential therapeutic targets for patients with neuromuscular and neurological conditions.
