Dermoscopy = Dermoscopy

다국어 초록 (Multilingual Abstract)

Dermoscopy improves diagnostic accuracy in pigmented and non-pigmented skin tumors. Recent reports suggest there is an increase in the rate of dermoscopy use among dermatologists. However, the use in Korean dermatologist seems to be low. In this talk, I will briefly introduce the utility of dermoscopy. Typical cases of benign and malignant tumors will be presented. - Benign melanocytic lesion: Pigment network, streaks, dots/globules, homogeneous blue pigmentation, pseudo-network (face), or parallel pattern (acral glabrous skin). - Seborrheic keratosis: Milia-like cysts, comedo-like openings, crypts, moth-eaten borders, fissures and ridges (brain-like or cerebriform appearance), fingerprint-like structures - Dermatofibroma: Central homogenous area, peripheral pigment network - Vascular lesions (hemangioma, angiokeratoma): Red, maroon, or red-blue to black lacunae - Malignant melanoma: Asymmetry, multiple colors, atypical pigment network, blue-white veil, atypical vascular pattern, irregular streaks, irregular dots/globules, irregular blotches, regression structures - Basal cell carcinoma: Arborizing blood vessels, leaf-like areas, large blue-gray ovoid nests, blue-gray globules, spoke wheel-like structures, ulcers, and shiny white structures. - Keratinocytic premalignant and malignant tumors: strawberry pattern, glomerular vessel, keratin mass, irregular hairpin vessels, polymorphous vessels.
