Currently, it is not included in the classification proposed by the International Society for the Study of Vascular Anomalies, although it can be considered a cutaneous vascular anomaly.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> SH typically presents as a usually asymptomatic, subcutaneous nodule with a bluish surface. It most often appears on the extremities, predominantly in middle-aged women. Histologically, SH is characterized by a lobular architecture. The lobes consist of dilated, interconnected, thin-walled vascular channels that form a sinusoidal pattern. The vessels are tightly packed with little stroma, giving rise to a pseudopapillary pattern in tangential sections of the walls, and thromboses and calcifications are typically observed at the center of the lesion.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> In our 3 cases, immunohistochemistry revealed findings similar to those described previously, suggesting that SH is better classified as a vascular tumor than a vascular malformation.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> Descriptions of the imaging characteristics of these tumors are scarce: they are described as solid lesions located in the subcutaneous tissue with slow vascular flow on magnetic resonance imaging and arteriography. A case report by Park et al.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> describes a hypoechoic lesion with no internal Doppler signal located between 2 parallel vessels, which may correspond to an artery and a draining vein, but reports no connection between the tumor and these vessels. This finding was not observed in any of our 3 cases. It has been proposed that the presence or absence of intralesional Doppler signal may be related to the presence of thromboses or areas of ischemia within the vessels that comprise the lesion. In our 3 cases, the tumor with the weakest intralesional Doppler signal had the highest levels of thrombosis, as well as intralesional hyperechogenic dots without posterior acoustic shadowing that correlated with calcifications on histology. Kitamura et al.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> previously described a case of SH with diffusely distributed intralesional hyperechogenic dots, some of which presented posterior acoustic shadowing, corresponding to calcifications on histology. These calcifications had been described earlier by Nakamura and Miyachi.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> Those authors proposed a relationship between the presence of calcifications and time since lesion appearance and low intralesional flow, in agreement with the characteristics of the first case described here. In the second and third cases color Doppler mode revealed intralesional vascularization, a rare finding in these lesions<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6,7</span></a> that histologically corresponds to vascular lumina. No calcifications were observed on histology and hyperechogenic dots were absent on ultrasound.</p><p id="par0035" class="elsevierStylePara elsevierViewall">In conclusion, we present 3 cases of SH and describe the corresponding ultrasound and histological findings. In 2 of the 3 cases we observed marked intralesional vascularization, an uncommon feature in this type of lesion. Although ultrasound allows assessment of lesion vascularization and the relationship with adjacent structures, there are no distinctive ultrasound findings that enable diagnosis, which is fundamentally based on histological findings.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Conflicts of interest</span><p id="par0040" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflicts of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0005" "titulo" => "Conflicts of interest" ] 1 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "NotaPie" => array:1 [ 0 => array:2 [ "etiqueta" => "☆" "nota" => "<p class="elsevierStyleNotepara" id="npar0005">Please cite this article as: García-Harana C, et al.
