Masson’s tumor: a soft tissue tumor simulating a tendon cyst. Case report

Introduction. Intravascular papillary endothelial hyperplasia (Masson's hemangioma or Masson’s tumor) is a benign vascular disease with an exuberant endothelial proliferation in normal blood vessels. Although relatively uncommon, its correct diagnosis is important because it can clinically be like both benign lesions and malignant neoplasms. We present a case of intravascular proliferative endothelial hyperplasia simulating a tendon cyst both clinically and on ultrasound. Case report. A 74-year old Caucasian female presented with a 4-month history of soreness and swelling in the fourth finger of the right hand. Ultrasound showed an oval mass with fluid content, referred to a tendon cyst. A wide surgical excision was subsequently performed. The final histological diagnosis was Masson’s tumor. Discussion. The pathogenesis of intravascular papillary endothelial hyperplasia is still unclear but the exuberant endothelial cell proliferation might be stimulated by an autocrine loop of endothelial basic fibroblast growth factor (bFGF) secretion. There are three types of papillary endothelial hyperplasia: primary, or intravascular; secondary, or mixed; and extravascular. The main differential diagnosis is against pyogenic granuloma, Kaposi sarcoma, hemangioma, and angiosarcoma. Conclusions. Masson's tumor can be like both benign lesions and malignant neoplasms clinically and on ultrasound. For this reason, the right diagnosis can be made only by histology, which reveals a papillary growth composed of hyperplastic endothelial cells supported by delicate fibrous stalks entirely confined within the vascular lumen.

Extracranial association of arteriovenous and venous malformations. Case report

Association of multiple vascular malformations of the face is a rare condition. An arteriovenous malformation (AVM) with a venous malformation as the draining vein is also a rarity. We report a case of extracranial mixed vascular malformations that deformed the normal architecture of the lower face. Removal of the AVM was followed by stability of the jaw and tongue malformation, indicating the AVM used the venous malformation as its draining vein. This approach spared the patient severe cosmetic and functional sequelae.

The cultural policy in Italy and the innovations of the XXI century

The paper analyzes the development of the first experiences of the sixteenth century cultural policy in Italy until the beginning of the twenty-first century with the institutional reform initiated by the Minister Dario Franceschini. In the pre-unification State it has been many important contributions of several local rulers who imposed conservation policies to prevent the dispersal of works of art. After the unification of Italy (1861) the laws of protection of the national heritage have helped to initiate the first important initiatives that have developed in practice only at the end of the twentieth century. Great institutional innovations and regulatory activated in the twenty-first century and of which this paper provides some important insights and deepening.

Architecture of the Landscape and Landscape of the Architecture in Japan. A dialogue between water and earth

It's very difficult in traditional Japanese culture separate the landscape from the architecture. The Japanese architectural culture has its roots in China but soon this culture has developed its own culture and an aesthetic that was the result of a long isolation from the rest of the world. Zen Buddhism and the constant relationship with nature define the main characteristics of Japanese architecture: minimalism and simplicity. The architecture is a perfect balance of harmony, proportion and purity. This paper aims to analyze the cultural roots of the relationship between architecture and landscape in Japan and where the characteristics previously defined are very important for to know the significance of the Japanese architectural thinking.

Gli scavi archeologici presso la Canonica di San Salvatore a Barzanò (Lecco)

Nel periodo compreso tra la primavera del 2007 e l'estate del 2010, presso la Canonica di San Salvatore a Barzanò, unitamente ai lavori di ristrutturazione e restauro, sono stati effettuati diversi interventi di assistenza e di scavo archeologico, inizialmente nelle aree esterne limitrofe e in un secondo tempo all'interno dell'edificio, nell’ambito di un piano di riqualificazione e di restauro del monumento commissionato dal Comune di Barzanò . La cripta e la sagrestia sono state indagate completamente, mentre all'interno dell'aula e della torre campanaria è stato effettuato uno scavo parziale fino a una quota mediamente di m -0.50 dal piano pavimentale: ciononostante, è stato possibile delineare complessivamente nove fasi archeologiche, sette delle quali definiscono le principali sequenze dell'evoluzione strutturale dell'edificio della Canonica.

Development of a simple and fast “DNA extraction kit” for sea food identification and marine species

Seafood products fraud, the misrepresentation of them, have been discovered all around the world in different forms as false labeling, species substitution, short-weighting or over glazing in order to hide the correct identity, origin or weight of the seafood products. Due to the value of seafood products such as canned tuna, swordfish or grouper, these species are the subject of the commercial fraud is mainly there placement of valuable species with other little or no value species. A similar situation occurs with the shelled shrimp or shellfish that are reduced into pieces for the commercialization. Food fraud by species substitution is an emerging risk given the increasingly global food supply chain and the potential food safety issues. Economic food fraud is committed when food is deliberately placed on the market, for financial gain deceiving consumers (Woolfe, M. & Primrose, S. 2004). As a result of the increased demand and the globalization of the seafood supply, more fish species are encountered in the market. In this scenary, it becomes essential to unequivocally identify the species. The traditional taxonomy, based primarily on identification keys of species, has shown a number of limitations in the use of the distinctive features in many animal taxa, amplified when fish, crustacean or shellfish are commercially transformed. Many fish species show a similar texture, thus the certification of fish products is particularly important when fishes have undergone procedures which affect the overall anatomical structure, such as heading, slicing or filleting (Marko et al., 2004). The absence of morphological traits, a main characteristic usually used to identify animal species, represents a challenge and molecular identification methods are required. Among them, DNA-based methods are more frequently employed for food authentication (Lockley & Bardsley, 2000). In addition to food authentication and traceability, studies of taxonomy, population and conservation genetics as well as analysis of dietary habits and prey selection, also rely on genetic analyses including the DNA barcoding technology (Arroyave & Stiassny, 2014; Galimberti et al., 2013; Mafra, Ferreira, & Oliveira, 2008; Nicolé et al., 2012; Rasmussen & Morrissey, 2008), consisting in PCR amplification and sequencing of a COI mitochondrial gene specific region. The system proposed by P. Hebert et al. (2003) locates inside the mitochondrial COI gene (cytochrome oxidase subunit I) the bioidentification system useful in taxonomic identification of species (Lo Brutto et al., 2007). The COI region, used for genetic identification - DNA barcode - is short enough to allow, with the current technology, to decode sequence (the pairs of nucleotide bases) in a single step. Despite, this region only represents a tiny fraction of the mitochondrial DNA content in each cell, the COI region has sufficient variability to distinguish the majority of species among them (Biondo et al. 2016). This technique has been already employed to address the demand of assessing the actual identity and/or provenance of marketed products, as well as to unmask mislabelling and fraudulent substitutions, difficult to detect especially in manufactured seafood (Barbuto et al., 2010; Galimberti et al., 2013; Filonzi, Chiesa, Vaghi, & Nonnis Marzano, 2010). Nowadays,the research concerns the use of genetic markers to identify not only the species and/or varieties of fish, but also to identify molecular characters able to trace the origin and to provide an effective control tool forproducers and consumers as a supply chain in agreementwith local regulations.

Comunicazione urbana nelle città storiche del Sol Levante: l'esperienza di Kyoto tra tradizione e innovazione

The book collects the Papers (from Europe, Asia and Latin America) presented at the Workshop organized by the ICOMOS International Committee in Historic Towns and Villages (CIVVIH) and by ICOMOS Italy in Palazzo Coppini (branch of Fondazione Romualdo del Bianco) in Florence (March 3-4, 2016) and focus on the comparison of different propositions of digital urban signage to realize a good quality of the “visit experience” in the historical towns, not only as urban marketing, but of a authenticity genuine culture. The urban culture founded on the identity and authenticity of every historical towns and their multilayered history must be the objective of an tourism of culture for the inhabitants and the visitors. The book focused its interest on the outstanding existing urban assets in Europe, Asia and Latin America, and heritage not sufficiently promoted.
