Pediatric pathology


The field of pediatric pathology is broad and covers the wide spectrum of abnormalities occurring during development, including fetal and neonatal periods and extending through childhood to the end of adolescence. The Department of Pathology at Northwell Health offers the full range of diagnostic pediatric services required by pediatricians and pediatric subspecialists at the Cohen Children’s Medical Center (CCMC). These services are offered by specialists in oncology, gastroenterology, nephrology, rheumatology, pulmonology, neurology, pediatric surgery, urology, neurosurgery, orthopedics, genetics and neonatology among others.

The Department of Pathology also offers diagnostic expertise to the Department of Obstetrics/ Maternal Fetal Medicine. Pediatric pathologists are not only involved in diagnostic pediatric services, but are also actively involved in patient oriented conferences as well as medical education and training. A division of pediatric pathology was established in 1991, and is currently led by Dr. Morris Edelman.

Timely results

Surgical pathology diagnoses are typically signed out in 24 to 48 hours, yet complex cases may take longer. Pediatric pathologists keep in constant communication with clinicians, keeping them informed about diagnoses and test results.

Special services

In collaboration with specialists in a number of disciplines, the Department of Pathology offers diagnostic services in all aspects of pediatric surgical pathology, intraoperative frozen section consultation, cytology, autopsy pathology, perinatal and placental pathology. State-of-the-art ancillary procedures are utilized in pediatric pathology, including immunohistochemistry, fluorescent in-situ hybridization (FISH), cytogenetics, electron microscopy (including cilia morphology) and molecular tests, as needed. The department actively participates in Children’s Oncology Group (COG) study protocols.
