Our board certified pathologists, led by Dr. Carla B. MacLeod, are experts in the field of cytopathology, with special training in the the performance and interpretation of FNA biopsies. They bring more than 40 years combined experience performing and diagnosing FNA biopsies. When requested, CBM Pathology communicates the preliminary diagnosis to the referring physician within four hours of the procedure and within an hour whenever possible. Our office is co-located with our histology and cytology lab, so specimens are processed in-house, reducing the time it takes to make an accurate diagnosis. CBM Pathology also evaluates on-site adequacy of FNAs and performs ancillary studies as needed, with material immediately submitted for special procedures and stains, such as lymphoma panels, microbiologic culture and immunocytochemical panels.

We perform FNA biopsies in a comfortable office setting in Gaithersburg, MD. Parking is easy and patient education is available (FNA Patient Brochure). For more information or to schedule an appointment, contact (301) 926- 4707, or
