OUTPATIENT CYTOPATHOLOGY CENTER (OCC)

is an independent medical practice, founded in 1991, offering comprehensive fine needle aspiration biopsy services. OCC is one of the first independent FNA practices established in the United States.

 

Fine needle aspiration, also called FNA, is a non-surgical procedure by which a sample of tissue is obtained by placing a very fine gauge needle (smaller in diameter than the needle used for drawing blood) into the lump for a few seconds to draw out cells for examination under the microscope. The procedure is fast, convenient, safe and well-tolerated by patients. No anesthesia or hospitalization is required. Patients can return to work immediately after the FNA biopsy.

At OCC, we perform over 2,500 Fine-Needle Aspiration (FNA) biopsies each year. Patients arrive at OCC from all over northeast Tennessee and western North Carolina, as well as surrounding states including Virginia, Kentucky, North Carolina, Georgia, and South Carolina. Full work-up of the FNA specimen is performed at OCC. Special studies such as immunocytochemical stains, flow cytometry and mycobacterial, fungal and bacterial cultures are obtained when needed. In addition to aspiration biopsy of palpable masses from virtually any palpable body site, ultrasound guided aspiration biopsies of non-palpable lesions are also routinely performed at OCC.

At OCC, FNA biopsies are performed and interpreted by three physicians, all of whom are Board Certified by the American Board of Pathology, have added board certification in Cytopathology and have the College of American Pathologists Certificate for Special Expertise in Ultrasound Guided FNA.

Dr. Rollins, founding member of OCC, was joined by Dr. Janet Stastny in 1999 and Dr. Yasmin Elshenawy in 2013. The Outpatient Cytopathology Center is accredited by the College of American Pathologists and is a CLIA accredited laboratory.
