Early diagnosis of melanoma by surface microscopy (dermatoscopy)

Abstract

The main objective of surface microscopy is the early and accurate diagnosis of melanoma in its initial phases of evolution and infiltration. Since the development of the dermatoscope in the 1990's, surface microscopy has become a simple technique. Differential diagnosis of pigmented skin lesions can be achieved with a diagnostic sensitivity of about 90 percent, and the proper differentiation of pigmented melanocytic and non-melanocytic lesions, and malignant and benign melanocytic lesions, may also be safely determined.

Dermatoscopy of non-melanocytic skin tumors

“…In 1893, Unna used oil immersion to make the skin more transparent and examined lupus vulgaris lesions. [2] The German dermatologist, Johann Saphier, published four reports on his method adding a built-in light source to the dermatoscope in 1920 and 1921. He was the first to use the term "dermatoscopy".…”

“…One of the most recent phenomena of the syndrome is the emergence of a new vulnerable population: the elderly (the United Nations [UN] define as elderly those individuals aged over 60 years in developing countries and 65 years in developed countries) 2 …”

Dermoscopy: basic concepts

“…New polarized light dermatoscopes do not require the use of fluid systems, but many workers still use polarized light dermatoscopes with fluid systems. The usual magnification provided by the dermatoscope is 10‐fold, but digital dermatoscopes already exist with magnifications of up to 70‐fold, with maintenance of image definition 21 …”
