In this study, we report about a patient with extra-uterine endometriosis (EM) in the abdominal wall muscle with evident metaplasia based on the abundant alpha smooth muscle actin (ASMA)-expressing myofibroblasts. Laparotomy excision of the abdominal wall EM was done following ultrasonographic evidence of a hypodense swelling in the right rectus abdominis, which was confirmed by MRI. Immunohistochemistry staining for ASMA and collagen I was done, with the results confirming that endometriotic stromal cells expressed both...

The malignant transformation of endometriosis is very uncommon. Whereas 75% of tumors arising from endometriosis arise in the ovary, location in extra-genital organs is rare and mesenchymal neoplasms are exceptional. A 47 year-old woman who underwent hysterectomy with bilateral salpingo-ooforectomy due to endometriosis 13 years before presented with abdominal pain. The magnetic resonance imaging (MRI) showed a 9.7×7.5 cm solid-cystic supravesical mass and a recto-vaginal tumor, as well as endometriotic nodules in the sigma, right parametrium and peritoneum that had significantly increased in size over a six months period...

We investigated whether serum osteopontin (OPN) levels are different according to specific phenotypes of adenomyosis and endometriosis. We conducted a prospective laboratory study in a university referral center for endometriosis between May 2005 and May 2013 and included 148 nonpregnant women, younger than 42 years, undergoing surgery for a benign gynecological condition and who had a preoperative pelvic magnetic resonance imaging (MRI). The presence of focal and/or diffuse adenomyosis was determined by pelvic MRI, and women were classified into 3 groups: no-adenomyosis (No-AM), isolated diffuse adenomyosis (DIF-AM), and focal adenomyosis with or without diffuse adenomyosis (FOC-AM)...

AIM: Preoperative workup of deep infiltrating endometriosis is limited in the evaluation of extragenital and extrapelvic disease and in distinguishing between the previous surgical scar and active lesion. Histological verification remains the gold standard for diagnosis. The aim of this study was therefore to evaluate positron emission tomography-computed tomography (PET/CT) with an experimental estrogen receptor tracer (16α-[18F]fluoro-17β-estradiol; [18F]FES) for accurate staging and non-invasive diagnosis of the disease...

Endometriosis occurs in 5%-10% of fertile women, usually in the pelvic region, such as the ovaries, uterine ligaments, pelvic peritoneum, and rectovaginal septum. A mesenteric endometriotic cyst is an exceptional observation and difficult to diagnose preoperatively. We report a case of a large mesenteric endometriotic cyst treated by laparoscopy. A 21-year-old Caucasian woman was admitted as an emergency to our Academic Hospital on the 30th day postpartum for abdominal pain and a palpable epigastric mass. A CT scan revealed a mass measuring 7...

Polypoid endometriosis is an uncommon variant of endometriosis which can mimic malignancy due to its presentation as masses. We present a case of polypoid endometriosis which simulated cervical malignancy both on clinical examination and on computed tomography (CT) scanning and discuss how magnetic resonance (MR) imaging, in particular Diffusion Weighted Imaging (DWI), can help to distinguish this condition from true malignancy and avoid invasive surgery.

A 29-year-old woman with known history of endometriosis was referred to colorectal outpatient clinic from gynaecology with a history of intermittent rectal bleeding and no associated bowel symptoms. Flexible sigmoidoscopy in concordance with pelvic MRI revealed a 3×2×2 cm sessile lesion in the anterior rectal wall. The lesion was also palpable as a firm mass on digital rectal examination. From the gynaecological point of view no intra-abdominal exploration was required; the sole rectal wall lesion was removed with the minimally invasive surgical technique of transanal endoscopic microsurgery...

Analysis of human urine is commonly used in biomonitoring studies to assess exposure to essential (e.g., Cu, Zn, Se) and non-essential (Pb, Cd, Pt) trace elements. These data are also used in epidemiological studies to evaluate potential associations between trace element exposure and various health outcomes within a population. Today most trace element analyses are typically performed using quadrupole-based inductively coupled plasma mass spectrometry (Q-ICP-MS). However, there is always the potential for spectral interferences with Q-ICP-MS instrumentation, especially when analyzing human specimens that may contain medications and other exogenous substances...

The aim of this review was to present the main aspects of pleural diseases seen with conventional and advanced magnetic resonance imaging (MRI) techniques. This modality is considered to be the gold standard for the evaluation of the pleural interface, characterization of complex pleural effusion, and identification of exudate and hemorrhage, as well as in the analysis of superior sulcus tumors, as it enables more accurate staging. The indication for MRI of the thorax in the identification of these conditions is increasing in comparison to computerized tomography, and it can also be used to support the diagnosis of pulmonary illnesses...

A 27-year-old woman with swelling left leg, groin pain, and increased serum CA125 level underwent FDG PET/CT to evaluate a pelvic mass revealed by an MRI performed from an outside hospital. A large hypermetabolic solid mass in the left pelvic wall and several lymph nodes with elevated FDG activity were noted, which indicated malignancy. However, histopathological examination demonstrated endometriosis.
