Lukas Marcelis

Lukas Marcelis is a Consultant Lecturer at the Faculty of Medicine, KU Leuven, Belgium, with an active research profile in pathology and oncology. His work focuses on diagnostic pathology of challenging tumor types, particularly soft tissue tumors, CNS neoplasms, and breast cancer pathology.

His research interests include:

• Soft tissue tumors and sarcomas with emphasis on molecular pathology
• Central nervous system tumors and their imaging characteristics
• Molecular diagnostics of gene fusions in tumor pathology
• Breast cancer subtypes and tumor microenvironment
• Lymphoma pathology including rare entities

Dr. Marcelis has published extensively from 2023-2025, with recent work focusing on undifferentiated small round cell sarcomas, perivascular epithelioid cell tumors in the CNS, and the role of gene fusions in soft tissue tumors. His publications often combine detailed case reports with comprehensive literature reviews that advance understanding of rare tumor entities.

His research demonstrates significant collaboration across multiple disciplines, particularly in breast cancer immunology and lymphoma pathology. Notable contributions include work on breast implant associated EBV-positive Diffuse Large B-cell lymphoma, highlighting his role in identifying and characterizing rare pathological conditions.
