Sažetak
Melanoma is a malignant tumor of the skin and mucous membranes, highly prone to early lymphatic or hematogenous metastasis. The incidence of melanoma is increasing significantly worldwide, making melanoma a major public health problem. Dermoscopy is a non-invasive diagnostic method which enables visualization of melanocytic and non-melanocytic structures that are not visible to the naked eye, thus linking clinical examination and pathohistological diagnostics. In the analysis of pigmented skin lesions, a two-step algorithm is used to first assess whether the lesion is melanocytic or non-melanocytic, based on the presence of typical structures such as pigment network, dots and globules, homogeneous pigmentation, radial streaks, and a parallel pattern. If the lesion is melanocytic, the second step is to determine whether it is a benign or malignant lesion using a number of methods such as pattern analysis, 7-point checklist, ABCD method and the Menzies method. In most melanomas, regardless of the method we use, dermoscopy reveals some of the specific criteria for this malignant tumor, such as atypical pigment network, atypical dots and globules, blue-white veil, irregular streaks, atypical vascular pattern, asymmetric pigmentation and regression structures. However, some clinical types have their own specific characteristics. Therefore, in this paper, we present the dermatoscopic features associated with a specific type of melanoma, which further enables the prediction of pathohistological diagnosis, prognosis, and outcome of the disease. With the development of dermoscopy, great progress has been made in the early diagnosis of melanoma, which is necessary for a successful treatment.
