A case of inflammatory myofibroblastic tumor of the orbit
Inflammatory myofibroblastic tumor (IMT) also known as inflammatory pseudotumor is a rare entity of neoplastic ori- gin; it usually occurs in children and adolescents and most commonly involves pulmonary and gastrointestinal sites; the
histological features of IMT include proliferation of spindle cells with a prominent inflammatory infiltrate consisting of
plasma cells and lymphocytes, with occasional eosinophils and neutrophils Here, the authors present a case with exclusively orbital localization
A case of angiolymphoid hyperplasia with eosinophilia of the orbit: anatomo-pathological features and treatment
Vernacular architecture and “historical seismography”: an experience research
The history of hearthquakes can be defined as a very ancient discipline, which roots are on the tales and on records of the most calamitous events whose evidence is not easy to be found because not written but handed down orally, and the history of seismology is a good example. The analysis of the historical archives and the carefull study of the projects concerning the territory and its structure, often reveals precious informations on events that involved the place, such as the most dangerous, i.e earthquakes, but little technical information about recovery or rebuilding is given in written documentation from the direct literature of the urban context and of the individual building is possible to deduce techiques and ways of the past used to inntervene to reply to the seismic needs of the build and from which the historic seismology originates from. The study of the history of earthquakes has become a systematic instruments to determine the areas where they can happen with a likely periodicity from the past century, and relates especially on historic seismology which has its historic reference store, even if it bases itself on oral sources. Our study, instead, based exclusively upon the analysis and the direct study of the architecture, aims to determinate the needs and the technical devices, peculiar to the art of building, but strictly connect to the local building culture of our territorial reference or research. The rich store of informations has allowed us to study different costructive typology, often determined by needs connected not only to the building tradition but also to the local seismic culture. In the areas exposed at high seismic risk, the regularity of the event can create a progressive rooting of the tecniques and behaviours leading to a clear protective view. When the system becomes part of the experience of the comunity, it stays in the people’s memory. The resident population are titular of their own seismic culture that generates non codified and non written rules but readable in the constructive characteristics of the buildings, in the general structure given by the territory. Every building bears witness to its own history and furnishes an enormous quantitaty of informations: the damage suffered, the repair work, intervention of prevention. A "global" local research and at the same time a systematic research of the frequencies of the constructive elements are developed. From this will of putting the basis for a systematic study of the “historical seismography” that promotes a technical normative of reference that is neither generic nor inducing inter-ventions little respectful of a context that only asks to be left in alone
Unusual case of traumatic neuroma of the orbit
Traumatic or amputation neuromas are neoformations developing after damage to a peripheral nerve. They are not proper tumors but rather a reactive process or a frustrated attempt of nerve regeneration. Traumatic neuromas are potentially found in every sensory peripheral nerve and often at the site of past surgical intervention, including orbital surgery. A 29-year-old Northern African migrant presented progressive exophthalmos and progressive loss of acuity in left eye, which had started about 6 months before after a cranio-facial trauma caused by a violent assault. MRI of the orbits showed a massive intra-orbital, intra-conical lesion, clearly compressing and dislocating the optic nerve and extending posteriorly to the orbital apex. Surgery was performed through lateral approach of Kroenlein and led to complete excision of the lesion. Histology revealed fibrotic, adipose and striated muscle tissues, a disordered, non-neoplastic overgrowth of small and large fascicles of nerves, inflammatory infiltrates, and fibrosis with sparse calcifications were diffusely observed in a background of fat, scar and striated muscle tissued. Patient was discharged on the fifth day in good health condition, without deficit of eye motion but without recovery of visual acuity. In conclusion, this case demonstrates that traumatic neuromas may arise in the orbit in patients with minor direct trauma to nerves and without previous surgical treatment
For “A Positive and Feasible Architecture”. The Contribution of Mario Chiattone to the Avant-Garde Movements of the Early 20th Century
The aim of this study is to highlight the contribution made by the Ticino-native architect, Mario Chiattone (1891–1957) to the development of modern language. His architectural designs, made in his studio in Milan between 1914 and 1915, highlight his artistic sensibility and demonstrate how he was particularly receptive to the needs of a rapidly evolving society. The working method employed by the architect, his extreme attention to architectural construction and the practicality of the solutions developed for his “Modern Metropolis” emerged clearly through the analysis carried out directly on the works using 3D imaging and reconstruction techniques. At the same time, the results of the archival-bibliographic research carried out simultaneously made it possible to contextualize Chiattone’s work in the light of historical and artistic developments in early-20th century Milan, including the numerous facets of his architectural output and the multiple sources of inspiration that characterized its development. A portrait emerged with unprecedented clarity of an extremely cultured, impassioned architect, of a tireless designer, open to experimentation and at the same time, respectful of tradition, far removed from propagandistic Futurist rhetoric, an advocate for a new, “positive and feasible” architecture
Epithelial cyst of the superior oblique muscle trochlea
Most of the congenital orbital cysts are choristomas such as dermoid or epidermoid and only in a few cases they are epithelial. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. We describe here the case of a 49-year-old man with an orbital cyst localized in the upper-nasal quadrant of the orbit and which was showing signs of a gradual enlargement and progression over the past weeks. Computed tomography revealed a cyst of 1.9 × 1.6 cm in size and located within the trochlea of the upper oblique muscle. The cyst was completely extirpated after orbitotomy performed by superciliary approach. Histopathology revealed a cyst with nonkeratinized cuboidal epithelium. Postoperative course was uneventful, without inflammation signs, and after 5 weeks excellent functional and aesthetic effects were achieved with no iatrogenic alteration of the ocular motility. © Informa Healthcare USA, Inc
