Dermatopathology focuses on diagnosis and observation of skin diseases along with infections, chronic and neo-plastic diseases. Dermatopathology involves the microscopic examination, description and interpretation of diagnostic assay specimens obtained from the skin. A dermato-pathologist performs a series of microscopic observations to detect the actual disease. Interpretation of skin specimens is difficult as several inflammatory skin diseases share identical basic inflammatory method or pattern. The ultimate identification needs clinical input and clinicopathological correlation. In some cases, extra specialized testing must be performed on biopsies, as well as technique, assay, microscopy, flow cytometry, and molecular-pathologic analysis.
