Dermatopathology may be a combination of dermatology and pathology which specialise in the study of cutaneous disease at the microscopic and molecular level. Sometimes dermatologists got to do skin biopsy which is examined under the microscope to seek out out precisely the explanation for disease. Biopsies also need specialized testing like immunofluorescence, immunohistochemistry, microscope , flow chemistry and molecular pathogenic analysis. Dermatopathology cases may sometimes include melanoma, and other skin disorders, infectious and pediatric diseases.
