| Popis: | Pigmented basal cell carcinoma (PBCC) is a tumour with distinct clinical features which occasionally may be difficult to differentiate from malignant melanoma (MM). The purpose of this study was to re-examine the epiluminescence microscopy (ELM) criteria for PBCC and to determine their statistical significance in the differential diagnosis of MM. Fifty histologically verified pigmented skin lesions (25 PBCCs and 25 MMs) were investigated using ELM for the presence of ELM criteria; their significance was determined by calculating the odds ratios. We found that individual ELM criteria have different weights of significance in the differential diagnosis of PBCC (leaf-like distribution of diffuse pigmentation, gradual thinning at the periphery and telangiectasia) and MM (pigment network, black and grey pigmentation, radial streaming, pseudopods, brown globules and black dots). Selected patterns of ELM criteria adjusted to the distinct types of pigmented skin lesions are characteristic features for preoperative diagnosis. The prevalence of distinct ELM criteria in PBCC and MM is of critical value in differentiating between the two types of lesions. |
