Abstract

In pigmented mucosal lesions, the structures observed during dermoscopy are unclear. Therefore, we examined whether the overall pattern and local structures of such lesions from dermoscopic images can become clearer by performing high-dynamic-range (HDR) image conversion of dermoscopic images. We analyzed the dermoscopic images of five labial mucosal melanoses. Among the reported dermoscopic findings, four patterns of the overall dermoscopic structure, nine localized structures, and seven basic colors were evaluated whether they were present or absent. The four patterns included reticular, linear, homogeneous, and globular pattern, the nine structures included ring-like, fish scale-like, V or U shaped, linear or curvilinear, hyphal-like, fingerprint-like, structureless, dots/globules and cobblestone, and the seven basic color included black, brown, light brown, gray, blue, white and red. These observations were made by two dermoscopy-specialist, who compared the original dermoscopic images with those after HDR image conversion. As a result, HDR image conversion of the dermoscopic images significantly improved the detection for the local structures but not for the overall patterns colors. The results suggest that HDR image conversion facilitates the identification of dermoscopic structures of pigmented mucosal lesions. On the other hand, the color tone of blood vessels may change from red to brown with HDR image conversion, leading to possible misidentification of vascular structure as pigmented structures.
