ABSTRACT
Objetive. To describe the morphological and vascular ultrasound findings of cutaneous melanoma locoregional metastasis, both in lymph nodes and in superficial soft tissues. To see if detection of these findings allows a sure diagnosis. Materials and methods. The morphological aspects of melanoma metastasis were evaluated with high-resolution ultrasound, and vascularisation by power color, by means the malignancy criteria previously described. Results. 71 loco-regional metastasis were found, in 32 patients: 15 lymph node metastases (21,2%) and 56 soft tissues metastases (78,8%). All of them were histologyc confirmation. In 19 cases metastasis were not detected by clinical evaluation. The lymph node metastasis had: low echogenicity (100%) with heterogeneous texture (66,7%); absence of echogenic hilus (93,3%); a ratio between longitudinal andtransverse diameters < 2 in most cases (86,2%); and peripheral or mixed vascularisation (86,6%). A statistic signification (p = 0,049) was proved between L/T ratio and vascularisation type. Soft tissues metastases presented: a maximal diameter between 3-27 mm (mean: 6,91); oval or round shape, sometimes lobulate; well-defined margins (100%); low echogenicity(100%); heterogeneous texture (64,3%); and they showedvascularisation even in the smallest lesions (< 5 mm). A statisticsignification (p = 0,006) was proved between the sizeand the vascularisation degree.Conclusion. US findings allow a suspicion diagnosis ofmelanoma locoregional metastasis even when metastasiswas not detected in physical exam (AU)
