  • Dermatoscopy utilizes the use of dermatoscope for examining skin lesions and has a low diagnostic specificity of current screening. These are usually in the form of a handheld device or a smart phone attachment and assist in screening of skin lesions. Some generations of dermatoscope can only capture high resolution images with improved optics and illumination, thus limited to only doctors or clinicians for screening of skin lesions. Other generations come with an attachment to smart phones with hardware and software co-designed platform, thereby facilitating the transfer of the images to neighborhood doctors for screening and clinical inference.
  • Histopathology is the microscopic examination of biological tissue. It suffers from trauma associated with invasive biopsy and prolonged period of intervention. Often, it may lead to psychiatric disorders which hamper their healing process. It is a three stage process involving biopsy of the wound tissue, followed by its biochemical processing and histological depiction for standardized clinical reporting. Although it quantifies the tissue involvement in a wound from its surface to its depth, it lacks in the context of being an invasive, ex vivo and time consuming procedure.
