Uncommon case of symmetrical fibrous hyperplasia of the hard palate.
2010
The fibrous hyperplasia of the palate (fibroma) is a benign tumor which has its origin in the soft tissue and whose frequency is estimated to be 1.2% on adult subjects. Rarely the size exceeds the cm, but in these cases a complaint of increasing difficulty of mastication and swallowing appears. We describe the case of a young white woman affected with two peculiar symmetric lesions of the secondary hard palate, that could be the consequence of an abnormal answer to a chronic inflammatory stimulation.
Solid variant of mammary "adenoid cystic carcinoma with basaloid features" merging with "small cell carcinoma"
2005
We describe a rare case of a solid variant of a mammary adenoid cystic carcinoma with basaloid features (sbACC) and its coexistence with a "small cell" carcinoma (SCC), identified and confirmed by histological and immunohistochemical observations: the absence of glandular structures and PAS-positive globules, positivity for neuroendocrine markers (NSE, synaptophysin and chromogranin), and negativity for 34betaE12 and SMA actin were the aspects suggesting the presence of SCC. Furthermore, positivity for CD10 was found both in sbA CC and in SCC, supporting the hypothesis that the two components share the same histogenetic myoepithelial origin and represent an example of dedifferentiation alon…
Renal endometriosis mimicking complicated cysts of kidney: report of two cases
2017
Endometriosis is a common gynecologic disorder characterized by ectopic endometrial tissue growth outside the uterine cavity. Although usually occurring in pelvic organs, endometrial lesions may involve urinary tract. Renal endometriosis is extremely rare and it has only occasionally been reported in the past. We report two cases of patients with renal cystic lesions, incidentally found at imaging techniques during oncologic follow-up for gastric sarcoma and melanoma, initially misinterpreted as complicated haemorrhagic cysts and then histologically characterized as renal localizations of extragenital endometriosis.
How to predict a high rate of inappropriateness for upper endoscopy in an endoscopic centre?
2010
Abstract BACKGROUND: Inappropriateness of upper endoscopy (EGD) indication causes decreased diagnostic yield. Our aim of was to identify predictors of appropriateness rate for EGD among endoscopic centres. METHODS: A post-hoc analysis of two multicentre cross-sectional studies, including 6270 and 8252 patients consecutively referred to EGD in 44 (group A) and 55 (group B) endoscopic Italian centres in 2003 and 2007, respectively, was performed. A multiple forward stepwise regression was applied to group A, and independently validated in group B. A <70% threshold was adopted to define inadequate appropriateness rate clustered by centre. RESULTS: discrete variability of clustered appropriaten…
Mesh or no mesh: a hamletic dilemma to prevent Renal Allograft Compartment Syndrome (RACS)
2014
Tension-free muscle closure is essential in kidney transplantation, both in adult and pediatric patients. Tight muscle closure may lead to renal allograft compartment syndrome either due to compression of the renal parenchyma or due to kinking of the renal vessels. It may also cause kinking of the transplant kidney ureter, wound dehiscence and incisional hernia. Many techniques have been proposed in an attempt to achieve tension-free closure. There is a wrong belief among surgeons that using prosthetic mesh may increase the incidence of infective complications in these immunosuppressed patients. Also, there is fear that one is not able to monitor the renal graft by ultrasound and perform bi…
Salvage (tertiary) breast reconstruction after implant failure
2011
Summary Background Salvage breast reconstruction is defined as a complete revision of a previous reconstruction in case of unsatisfactory results or failure of primary or secondary breast reconstruction. We have termed this ‘tertiary breast reconstruction'. This article presents our experience with tertiary reconstructions, including the indications, method of reconstruction and outcomes. Methods A retrospective note review was performed for all patients who underwent breast reconstruction with autologous tissue under one surgeon between 2002 and 2009 at the University Hospital, Ghent. Out of these 688 patients, 54 patients (7.8%) required tertiary surgery with autologous tissue after failu…
Aneurysmal bone cyst of the spine in adult patients: A systematic review and comparison of primary vs secondary lesions.
2021
Background: Spine aneurysmal bone cysts (ABCs) rarely occur in adults. Primary and secondary lesions may show some differences and require appropriate treatments. Objective: To systematically review the literature on adult spine ABCs. Methods: PubMed, EMBASE, Scopus, and Web-of-Science were searched. Clinical-radiological features, treatments, and outcomes were analyzed and compared between primary vs secondary adult spine ABCs. Results: We included 80 studies comprising 220 patients. Primary spine ABCs were more frequent (76.4%). Main symptoms were lower-back-pain (42.8%) and motor deficits (31.2%). Tumors were mostly thoracic (31.4%) or cervical (26.8%), showing lytic (70.4%) and/or cysti…
Transcranial Doppler ultrasonography in the assessment of cerebral circulation arrest: improving sensitivity by trancervical and transorbital carotid…
2009
INTRODUCTION: Transcranial Doppler (TCD) can detect the cerebral circulation arrest (CCA) in brain death. TCD is highly specific, but less sensitive because of false-negatives accounting for up to 10%. The aim of the study was to explore the diagnostic accuracy of TCD and to determine whether it can be augmented by strategies such as the insonation of the extracranial internal carotid artery (ICA) and sequential examinations. METHODS: Data of 184 patients, who met clinical criteria of brain death, observed from 1998 through 2006, were retrospectively reviewed. The study of cerebral arteries was performed through the transtemporal approach, suboccipital insonation of the vertebro-basilar sys…
Tuberous Breast
2017
Background Tuberous breast (TB) is a rare congenital deformity, which may appear in different clinical forms representing various degrees of a single pathological entity. The worst cases are characterized by severe hypoplasia. Following a detailed analysis of the available relevant literature and a significant number of treated cases, in this article, the authors propose a new classification, with the aim of summarizing and simplifying a more intuitive categorization of the malformation, considering all the clinical aspects and including all types of TBs, even the minor ones, thus allowing a more immediate diagnosis and surgical planning. Methods Between September 2006 and December 2015, 78…
The accuracy of sentinel lymph node biopsy in the treatment of multicentric invasive breast cancer using a subareolar injection of tracer.
2008
BACKGROUND: The aim of this study was to evaluate the feasibility and the accuracy of sentinel lymph node biopsy in multicentric breast cancer (MBC) performed by means of a subareolar (SA) injection of both 99Tc-labeled human albumin colloid and lymphazurin. METHODS: Between January 2002 and October 2007, 34 patients with MBC with clinically negative axilla underwent sentinel lymph node biopsy (SLNB) followed by total axillary node dissection (AD). Overall successful identification rate of SLN was 100%; there were no false negatives and overall accuracy rate was 100%. RESULTS: The mean number of sentinel lymph nodes (SLNs) identified was 1.8 +/- 0.88 (range = 1-4); the mean number of axilla…
