MANAGEMENT OF LEIOMYOMA OF THE TRANSVERSE COLON: CASE REPORT
2013
Colonic leiomyoma is a mesenchymal tumor that arises from the muscularis mucosae or muscularis propria and is composed of well-differentiated smooth muscle cells with no atypia. It is often incidentally found since its growth affects the submucosal layer and the lesion is covered with normal epithelium. Endoscopic ultrasonography is recommended to define the grade of infiltration of the tumor and eventually lymph node involvement. Histological examination is critical to establish the nature of the tumor and its behaviour. In the case of a voluminous tumor surgical treatment is needed. we report case of a patient that underwent colonoscopy showing the presence of a neoformation at 70 cm from…
COULD THE ENDOSCOPIC RESECTION OF A LARGE RECTAL LEIOMYOMA BE AN EFFETCIVE AND SAFE TECHNIQUE?
2016
Summary. Rectal leiomyomas are a rare conditions, with low reported incidence in literature and constitute about 0.1% of rectal tumours; in fact rectal leiomyomas occur in approximately 1 out of 2000-3000 rectal tumors. We report on a patient with a 3 cm semi-pedunculated colonic leiomyoma, which was successfully removed by endoscopic polypectomy after normal saline-epinephrine submucosal injection. When we encounter a tumor during a colonoscopic examination, we usually evaluate the tumor carefully and perform an endoscopic resection when we judge it is appropriate. When a symptomatic smooth muscle tumors smaller than 2 cm are incidentally found on colonoscopy, surgical resection is unneces…
Combining split-and-merge and multi-seed region growing algorithms for uterine fibroid segmentation in MRgFUS treatments
2016
Uterine fibroids are benign tumors that can affect female patients during reproductive years. Magnetic resonance-guided focused ultrasound (MRgFUS) represents a noninvasive approach that uses thermal ablation principles to treat symptomatic fibroids. During traditional treatment planning, uterus, fibroids, and surrounding organs at risk must be manually marked on MR images by an operator. After treatment, an operator must segment, again manually, treated areas to evaluate the non-perfused volume (NPV) inside the fibroids. Both pre- and post-treatment procedures are time-consuming and operator-dependent. This paper presents a novel method, based on an advanced direct region detection model, …
Tumore adenomatoide
2006
Adenomatoid tumour is a neoplastic process of discussed origin, but the immunohistochemical phenotype leads a mesothelial derivation. The preferential site of origin is the genital apparatus of both sexes, however extragenital cases have been described. The histological pattern varies from tubular formation, to solid growth, to cystic areas. In the present report we described a case of Adenomatoid tumour of the uterus body in a 46 years old patient.
Impact of FIGO type 3 uterine fibroids on in vitro fertilization outcomes: A systematic review and meta‐analysis
2023
Background: The effect of FIGO (the International Federation of Gynecology & Obstetrics) type 3 myomas on in vitro fertilization (IVF) is uncertain. Objectives: To evaluate whether FIGO type 3 myomas affect IVF outcomes, through a systematic review and meta-analysis (CRD42022379700). Search strategy: Electronic databases were searched until November 15, 2022. Selection criteria: Studies evaluating the effects of FIGO type 3 myomas on IVF outcome. Data collection and analysis: Pooled results were expressed as odds ratios (OR) with 95% confidence intervals (CI). Heterogeneity was assessed using Higgins I2 . Sources of heterogeneity were explored with sensitivity and subgroup analyses. Mai…
Multifocal adult rhabdomyoma of the head and neck: a case report and literature review.
2008
Adult rhabdomyoma is a rare, usually solitary, primary tumour of striated muscle origin that almost exclusively presents in the head and neck region with predilection for male. We herein present a rare case of a multifocal adult rhabdomyoma in a 72-year-old woman. The lesions were located, the first one in the area of the left aryepiglottic fold and the second one right cervical arising from oesophagus. The diagnosis of the cervical mass was obtained prior to resection through cytological examination (FNAC). We discuss the clinical, cytological and histological findings and we provide a brief review of the literature on this entity.
Characterization of the epigenetic modifications in human uterine leiomyomas and evaluation of their potential as therapeutic targets in vitro
2023
Los miomas o fibromas uterinos (UL) son los tumores benignos más frecuentes en las mujeres en edad reproductiva. A pesar de su elevada prevalencia y de las diferentes opciones de tratamiento, no existe terapia eficaz para la reducción del tamaño de los UL que sea mínimamente invasiva y sin efectos secundarios a largo plazo. Su patología tumoral permanece desconocida, lo que dificulta el desarrollo de tratamientos seguros y eficaces. Por lo tanto, la identificación de los mecanismos moleculares implicados en la generación de UL podría permitir el desarrollo de tratamientos más eficaces. Las modificaciones epigenéticas están implicadas en el desarrollo de los tumores y pueden revertirse media…
Sporadic oral angiomyolipoma: Case report
2007
Angiomyolipoma (AML) is a rare, benign tumour composed of a variable proportion of lipocytes, smooth muscle and thick-walled blood vessels. AML is part of a family of tumours arising from perivascular epithelioid cells (PEComas), and many cases are associated with tuberous sclerosis, with the kidney being the most frequent site involved. We report a case of sporadic AML in the hard palate of a 52-year-old male, an extremely unusual location for this tumour. Differentiation from other benign and malignant oral mesenchymal lesions depends on recognition of the three histologic components, and immunohistochemical techniques may be helpful. AML occurring in the head and neck do not express HMB-…
A fully automatic 2D segmentation method for uterine fibroid in MRgFUS treatment evaluation
2015
PurposeMagnetic Resonance guided Focused UltraSound (MRgFUS) represents a non-invasive surgical approach that uses thermal ablation to treat uterine fibroids. After the MRgFUS treatment, an operator must manually segment the treated fibroid areas to evaluate the NonPerfused Volume (NPV). This manual approach is operator-dependent, introducing issues of result reproducibility, which could lead to errors in the subsequent follow-up phase. Moreover, manual segmentation is time-consuming, and can have a negative impact on the optimization of both machine-time and operator-time. MethodTo address these issues, in this paper a novel fully automatic method based on the unsupervised Fuzzy C-Means cl…
Goserelin acetate to avoid hysterectomy in pre-menopausal women with fibroids requiring surgery
1999
Objective: To obtain information on the efficacy of repeated short cycles of GNRH agonist treatment in order to avoid hysterectomy in near-menopausal women with symptomatic fibroids. Study design: 72 pre-menopausal women (mean age 50 years) with one or more uterine fibroids >10 cm in diameter, symptomatic menorrhagia lasting three months or more and haemoglobin=9 g/dl entered the study. The patients were randomized with ratio of approximately 1:4 to: (a) immediate surgery; or (b) treatment with goserelin acetate. Patients randomized to goserelin acetate received a first cycle of 3.6 mg depot once every 28 days for four months. They were followed-up for three years. If menorrhagia was observ…
