Immunohistochemical Expression of Wt-1 Helps to Differentiate Cutaneous Vascular Tumors from Vascular Malformations

Study on the Application of Ultrasonic Image Analysis Technology Combined with the Analysis of Intestinal Nervous System in the Treatment of Intestinal Duplication in Children

This paper retrospectively analyzed 28 cases of children diagnosed with repeated intestinal malformations in our hospital from October 2014 to November 2016. The characteristics of ultrasound sonograms of children were evaluated. The images of intestinal repetitive malformations were classified and summarized to identify their common sites, the characteristics of various types of ultrasound sonograms, the main points of ultrasound diagnosis and identification, and the experience of ultrasound workers in daily inspection of children with repetitive malformations of the digestive tract. We analyzed the images of some common complications caused by repeated bowel malformations and identified the main points of ultrasound diagnosis. We then compared the results of ultrasound with other imaging findings, surgery, and pathologic results. At the same time, some special types of repeated bowel malformations were analyzed, discussed, and summarized to improve the understanding of ultrasound examination of gastrointestinal diseases in children, and show the superiority of children's abdominal intestine ultrasound. This study found that the ultrasound diagnosis of children with intestinal repetitive deformities has a high detection rate, clear images, clear anatomic levels, and clear blood flow conditions. Compared with other imaging methods, ultrasound has strong operability, real-time dynamics, strong specificity, and no radiation, and things are not easily misdiagnosed and missed. Therefore, ultrasound can be used as the preferred method for preoperative diagnosis, differential diagnosis, and postoperative follow-up review of repeated intestinal malformations in children.

[Diagnosis and management of vascular malformations : Interdisciplinary teamwork in demand]

Vascular anomalies are very rare, but can occur in children and adults in almost every region of the body. Due to the complexity of this disease, the path to a definitive diagnosis is often difficult. It requires interdisciplinary teamwork with close exchange of information between the individual treatment partners to reach the correct diagnosis and then to start the best therapy. This article provides an overview of the main types of vascular malformations from a clinical, imaging, and histological point of view, following the current classification of the International Society for the Study of Vascular Anomalies (ISSVA).

Acquired Elastotic Hemangioma: A Case Report and Review of 49 Previously Reported Cases

In the past decades, there was a considerable advance in regard to recognition of morphologic findings and classification of several benign and malignant vascular proliferations. In 2002, attention was called by Requena et al to a new variant of cutaneous hemangioma named acquired elastotic hemangioma. In this article, a case of acquired elastotic hemangioma is reported with documentation of clinical, dermatoscopic, histopathological, and immunohistochemical findings. A systematic review of the previously 49 reported cases is provided. The criteria for clinical and histopathological diagnosis are highlighted.

Pyogenic granuloma over the venous component of a mixed vascular malformation

A 52-year-old man presented with a rapidly growing red tumor on the central neckline. It had appeared over a congenital flat and pinkish vascular lesion that involved the shoulder and the upper anterior area of his chest. Intermingled with the pinkish stain, there were also some blue nodules several millimeters in diameter. Histopathologic examination revealed that the full lesion was a mixed venous-capillary malformation. The red tumor was excised and diagnosed as a pyogenic granuloma developing over the venous component of the vascular malformation. To our knowledge, a pyogenic granuloma growing over a venous malformation has not been previously described.
