Oral and Maxillofacial Pathology services of the Department of Pathology at North Shore-LIJ Health System is a recognized center of excellence for the study of tumors and conditions of the oral mucosa, jaws, salivary glands and structures adjacent to the oral and maxillofacial complex. Lymphoproliferative processes and non-neoplastic processes, including immune mediated mucosal diseases, are also a focus of the group.


Interpretations of oral and maxillofacial specimens from the salivary glands, maxillofacial region, oral mucosa, and paranasal sinuses are provided by board certified oral and maxillofacial pathologists. Our pathologists have specialty qualifications and considerable expertise and experience in the varied pathological processes that affect the mouth.

In addition, pathology expertise in general anatomic surgical pathology, head and neck pathology, endocrine, bone, pediatric, hematopathology, dermatopathology, neuropathology, molecular, and laboratory medicine combines a depth of comprehensive services necessary to meet the demands of the referring clinicians and the patients they serve. The research faculty of Feinstein Institute is an important component of the directed efforts in translational research related to head and neck cancers and inflammatory processes.

Slides sent for consultation are returned automatically with an accompanying pathology report, upon completion of the consultative diagnosis.

Biopsy kits (formalin bottles, requisition forms, biohazard bags and mailers with prepaid postage are available upon request. Submissions of microscopic slides or tissue blocks for consultation purposes are accepted.
