Dermatopathology is a subspecialty of dermatology and also of surgical pathology that focuses on the study of cutaneous diseases at a microscopic level. It also encompasses analyses of the potential causes of skin diseases at a cellular level. Dermatopathologists work in close association with dermatologists. In fact, most of them are trained primarily in dermatology themselves.

Dermatologists are able to recognize most skin diseases based on their appearances, anatomic distributions, and behavior. Sometimes, however, those criteria do not allow a conclusive diagnosis to be made, and a skin biopsy is taken to be examined under the microscope. That process reveals the histology of the disease and results in a specific diagnostic interpretation. In some cases, additional specialized testing needs to be performed on biopsies, including immunofluorescence, immunohistochemistry, electron microscopy, flow cytometry, and molecular-pathologic analysis.

Both Dr. Zemtsov and UDC Dermatopathology laboratory are CLIA certified and employs two certified histotechnologists. Dr. Zemtsov was trained by late professor Ackerman at NYU School of Medicine, a world renowned dermatopathologist, and Dr. Bergfeld at the Cleveland Clinic. Furthermore Dr. Zemtsov has published a few articles in peer review dermatopathology journals and is also Associate Professor at Indiana School of Medicine.
