The present study describes a case of a painful supraclavicular soft-tissue metastasis of a skin melanoma invading the brachial plexus in a 38-year-old male. The patient was treated twice with radiofrequency ablation (RFA) under computed tomography (CT) guidance, which caused tumoral necrosis. The patient was originally referred with a 7-cm metastasis in the right supraclavicular fossa, which caused intractable pain and a degree of numbness. These symptoms were unresponsive to chemotherapy and radiotherapy and the pain was not controlled using narcotic analgesics. The lesion was treated with CT-guided RFA causing necrosis, relieving the pain and sparing the patient from using analgesics. The pain recurred 19 months thereafter and a CT scan revealed an 8-cm mass in the right supraclavicular space. The patient underwent repeat CT-guided RFA, which reduced the pain to a level that was controlled with minor oral analgesics. In conclusion, in this case of a painful supraclavicular soft-tissue metastasis invading the brachial plexus, which was intractable to chemotherapy and radiotherapy, RFA was feasible and offered substantial palliation of the symptoms, freedom from the use of narcotic analgesics and improvements to the quality of life.

Cystic formations within the liver are a frequent finding among populations. Besides the common cystic lesions, like simple liver cysts, rare cystic liver lesions like cystadenocarcinoma should also be considered in the differential diagnosis. Thorough knowledge of each entity's nature and course are key elements to successful treatment. Detailed search in PubMed, Cochrane Database, and international published literature regarding rare cystic liver lesions was carried out. In our research are included not only primary rare lesions like cystadenoma, hydatid cyst, and polycystic liver disease, but also secondary ones like metastasis from gastrointestinal stromal tumors lesions. Up-to date knowledge regarding diagnosis and management of rare cystic liver lesions is provided. A diagnostic and therapeutic algorithm is also proposed. The need for a multidisciplinary approach by a team including radiologists and surgeons familiar with liver cystic entities, diagnostic tools, and treatment modalities is stressed. Patients with cystic liver lesions must be carefully evaluated by a multidisciplinary team, in order to receive the most appropriate treatment, since many cystic liver lesions have a malignant potential and evolution. © 2013 Baishideng Publishing Group Co., Limited.

Pancreatic neuroendocrine tumors (PNETs) share a unique genetic identity, functional behavior, and clinical course. Compared with tumors of the exocrine pancreas, they are rare and show a different biologic behavior and prognosis. On the basis of data from recent studies, all PNETs, outside of small insulinomas, should be considered potentially malignant and treated accordingly. Untreated tumors have a high possibility to grow locally into adjacent structures or spread to distant organs. Although surgical excision irrespective of tumor functioning or nonfunctioning state remains the cornerstone of therapy, providing the best disease-free and survival rates to date, the understanding of the genetic nature of the disease yields new 'targets' to consider in drug development. The aim of this review is to summarize all recent advances of genetic research and new drug development in terms of PNETs, especially their genetic identity and subsequent alterations leading to the development of near or total malignant activity, and the new medical treatment strategies of this potentially curable disease on the basis of therapeutical agents acting, where possible, at the genetic level. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Solid pseudopapillary tumor of the pancreas is a rare pancreatic tumor that predominantly occurs in young non-Caucasian women. Although most tumors show benign behavior, malignant degeneration may occur. A case of solid pseudopapillary pancreatic tumor in a Caucasian woman is presented that was investigated by endoscopic ultrasonography (EUS), computed tomography, magnetic resonance imaging and EUS-guided fine needle aspiration. The patient underwent surgery and radiological findings are correlated with histopathology. The preoperative diagnosis of solid pseudopapillary tumor of the pancreas is challenging, frequently leading to imaging by multiple different modalities.
