Ziad Peerwani, MD Appointed as Medical Director of Cleveland Clinic Laboratories

Ziad Peerwani, MD has been appointed as the new Medical Director for Cleveland Clinic Laboratories, effective September 1, 2021.

Dr. Peerwani was most recently CEO of Union71, based in Abu Dhabi, where he oversaw 17 laboratories, outpatient phlebotomy services, and the performance of more than 15 million lab tests per year.

“We look forward to the experience Dr. Peerwani brings to leading and growing our outreach laboratory services,” says Brian Rubin, MD, PhD, Chair of Cleveland Clinic’s Robert J. Tomsich Pathology & Laboratory Medicine Institute.

Ziad Peerwani, MD

About Dr. Peerwani:

In August 2020, Dr. Peerwani was appointed to carve out all laboratory services from SEHA, the government-owned health care system in Abu Dhabi, into an independent company while minimizing the impact on patient care and operations.

After successfully establishing the new business—Union71—Dr. Peerwani was appointed as its first CEO on October 4, 2020. During Union71’s first year, Dr. Peerwani stabilized and grew the laboratory while substantially outperforming Year 1 projections. Eventually, in March 2021, Union71 merged into PureHealth, with Dr. Peerwani supporting another transition.

Before serving as Union71’s CEO, Dr. Peerwani was Chairman of Pathology & Laboratory Medicine at Tawam Hospital, the regional cancer center for SEHA.  He was also the section chief of hematopathology and flow cytometry, providing the majority of clinical sign-out over the years.

Prior to joining Tawam in 2014, Dr. Peerwani practiced general anatomic and clinical pathology at Baylor Scott & White All Saints Medical Center — Fort Worth.

Dr. Peerwani completed his residency and fellowship in Anatomic Pathology, Clinical Pathology, and Hematopathology at Cleveland Clinic.

Diagnosis of Oncocytic Salivary Gland Tumors

Presented by Mobeen Rahman, MD

The diagnosis of oncocytic salivary gland tumors can be challenging, especially on core needle biopsies.

Dr. Mobeen Rahman, staff Head & Neck pathologist, discusses an interesting case that explores this issue.

As part of our educational mission for our clients and communities, Cleveland Clinic Laboratories presents the Pathology Insights video series.

CC-SIGN® Head & Neck Gene Fusion Next-Generation Sequencing Panel

CC-SIGN® Head & Neck Gene Fusion Next-Generation Sequencing Panel

This customized, 30-gene Next-Generation Sequencing (NGS)-based laboratory-developed test is intended for use in the diagnosis and management of benign and malignant tumors of the head and neck.

In particular, salivary gland neoplasms are broadly covered by this panel—which also covers select mesenchymal tumors and other lesions arising in head and neck sites.

The CC-SIGN® Head & Neck Gene Fusion NGS Panel is available as part of a comprehensive, diagnostic consultation or as a stand-alone test. This laboratory-developed test interrogates gene targets associated with known translocations in salivary gland and other solid tumors. Additionally, this panel identifies the corresponding fusion partner which may be helpful in the selection of treatment targets in some cases.

Results are delivered within 14 days of specimen receipt, allowing for a timely, definitive diagnosis in difficult salivary gland tumors and other head and neck lesions in a stand-alone fashion or with the support of our expert pathologists.
