OBJECTIVE: The transfer of long noncoding RNAs (lncRNAs) via exosomes to modulate recipient cells represents an important mechanism for disease progression. Antisense hypoxia-inducible factor (aHIF) is a well-known angiogenesis-related lncRNA. Here, we aimed to investigate the clinical implications of aHIF and exosomal aHIF in endometriosis and the involvement of exosome-shuttled aHIF in endometriosis angiogenesis. STUDY DESIGN: The distribution and expression of aHIF in ectopic, eutopic, and normal endometria was evaluated...

Angiogenesis is an essential process involved in various physiological, including placentation, and pathological, including cancer and endometriosis, processes. Melatonin (MLT), a well‑known natural hormone secreted primarily in the pineal gland, is involved in regulating neoangiogenesis and inhibiting the development of a variety of cancer types, including lung and breast cancer. However, the specific mechanism of its anti‑angiogenesis activity has not been systematically elucidated. In the present study, the effect of MLT on viability and angiogenesis of human umbilical vein endothelial cells (HUVECs), and the production of vascular endothelial growth factor (VEGF) and reactive oxygen species (ROS), under normoxia or hypoxia was analyzed using Cell Counting kit 8, tube formation, flow cytometry, ELISA and western blot assays...

INTRODUCTION: Villar's nodule is an umbilical endometriosis without anterior or ongoing pelvic endometriosis. The primitive location of this nodule at the umbilical level is rare. Its etiopathogenesis remains unclear. PRESENTATION OF CASE: We report a case of umbilical endometriosis with unusual clinical expression in a woman in the reproductive years with no surgical history and no known history of endometriosis. Endometriosis manifested as progressive transformation of the normal umbilicus into several small nodules, with bleeding coinciding with the menstrual cycle...

Endometriosis is a common multifactorial gynecological disorder defined as the proliferation of endometrial tissue outside of the uterine cavity. Neuroangiogenesis (co-recruitment of nerves and blood vessels) is believed to play an integral part in the establishment and growth of endometriotic lesions. We hypothesized that exosomes derived from abnormal endometrium may serve as the second identifier of endometriosis and play an important role in the development of endometriosis by regulating neuroangiogenesis...

Endometriosis is a common gynecological disease and the pathogenesis is not clearly understood. Previous studies have demonstrated via microarray techniques that microRNA (miR)‑449b was significantly downregulated both in ectopic and eutopic endometrium in patients with endometriosis. In the present study, the aberrant expression of miR‑449b was further confirmed by reverse transcription‑quantitative polymerase chain reaction. It was demonstrated that miR‑449b‑3p was downregulated in ectopic and eutopic tissues from women with endometriosis, and the same expression pattern was observed in endometrial stromal cells (ESCs) of eutopic endometrium from women with endometriosis and normal endometrium from women without endometriosis...

STUDY QUESTION: How does hypoxia-mediated downregulation of chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) promote angiogenesis in endometriosis? SUMMARY ANSWER: Suppression of COUP-TFII by hypoxia stimulates angiogenesis through induction of angiogenin (ANG). WHAT IS KNOWN ALREADY: The level of COUP-TFII is downregulated in endometriotic tissues, and downregulation of COUP-TFII contributes to the development of endometriosis...

Desmoid-type fibromatosis (DF) or desmoid tumours are rare benign soft tissue tumours of musculo-aponeurotic origin, which have no malignant potential but are locally aggressive and can result in significant morbidity. They may be hereditary (in association with FAP, i.e. familial adenomatous polyposis syndrome resulting from APC gene mutation) or sporadic, with hereditary cases having a much higher risk of developing DF compared to sporadic ones. Desmoids are known to occur in previous surgical scars. However, previous laparoscopic port site/trocar site is an extremely uncommon site for sporadic desmoids, with only two cases of sporadic laparoscopic trocar site desmoids (occurring in absence of FAP) reported in world literature...

Background: Umbilical endometriosis or Villar’s nodule is uncommon. Incidence goes up to 0.5-1.2% of all patients with endometriosis. As far as 2012, only 109 cases of umbilical endometriosis have been reported worldwide, there is no incidence reports in Mexico. Clinically, it’s a solitary node, solid and well defined, colored red, blue or black and it’s ocassionally accompanied by bleeding and dysmenorrhea. The treatment can be medical or surgical and it consists of painkillers, and hormonal suppression using GnRH analogues, hormonal contraceptives, danazol or progesterone...

BACKGROUND Catamenial pneumothorax (CP) is a spontaneous pneumothorax commonly associated with menstrual periods. Endometrial tissues most commonly involve the pelvic region. However, after the pelvis, the lungs are most frequently involved. Thoracic endometriosis should always be suspected in young women presenting with CP. CASE REPORT A 30-year-old woman with history of endometriosis presented with chief complaint of umbilical pain. A computerized tomography (CT) scan of the abdomen and pelvis was performed, which showed an incidental finding of a large right-sided pneumothorax...

Primary cutaneous endometriosis is a rare condition. It appears without a prior history of surgical procedure and the umbilicus is the most frequently involved area. Primary umbilical endometriosis, or Villar's nodule, usually presents as a painful nodule. Its differential diagnosis may be challenging. Although histopathological assessment represents the gold standard for diagnosis, cutaneous ultrasonography may be useful in guiding the surgical treatment. Ultrasonographic features of cutaneous endometriosis have not yet been fully explored in the literature...

Endometriosis is defined as the implantation of endometrial tissue outside of the uterine cavity. It affects approximately 10% of women of childbearing age. Umbilical endometriosis is rare and its pathophysiology is poorly known. We report the case of a 42-year old nulliparous female patient with a 5-year history of myomectomy, presenting with cyclic pain associated with umbilical mass. The diagnosis of umbilical endometrioma was made and confirmed by the histological examination of the surgical specimen. Treatment was based on wide excision of the mass associated with pelvis exploration and umbilical plasty...

Endometriosis is an inflammatory disease marked by ectopic growth of endometrial cells. Mesenchymal stromal cells (MSC) have immunosuppressive properties that have been suggested as a treatment for inflammatory diseases. Therefore, the aim herein was to examine effects of allogeneic MSC on endometriosis-derived cells in vitro as a potential therapy for endometriosis. MSC from allogeneic adipose tissue (Ad-MSC) and stromal cells from endometrium (ESCendo ) and endometriotic ovarian cysts (ESCcyst ) from women with endometriosis were isolated...

Primary umbilical endometriosis is a rare phenomenon accounting for 0,4-1,0% of extragenital endometriosis. Despite the fact that it mostly presents as a typical cyclic umbilical discharge coincidental with a palpable mass, the diagnosis is often delayed due to its low prevalence, as was seen in the presented case. The exact pathogenesis is still unclear. The golden standard for diagnosis is histopathological examination, but diagnostic tools like ultrasound, MRI or CT scan can be helpful. The differential diagnosis includes a wide range of disorders...

Umbilical hernias are rather common in the General Surgery clinic; however, endometriosis of an umbilical hernia is rare. It is especially unusual to have endometriosis of an umbilical hernia spontaneously occur compared to occurring at a site of a prior surgery. We present a case of spontaneous endometriosis of an umbilical hernia without prior surgery to her umbilicus. She had not presented with the usual symptoms of endometriosis and it was not considered as a diagnosis prior to surgery. Umbilical endometriosis is rare but usually occurs after prior laparoscopic surgery...

Umbilical endometriosis is rare, representing only 0.5-1% of all cases of extragenital endometriosis. In infertile women, endometriosis may be as prevalent as 50%. Numerous differential diagnoses are present, hence the clinical diagnosis of umbilical tumours is intricate. In a 33-year-old woman, an umbilical tumour presented 12 months prior to referral. On referral, no cyclic bleeding was noticed, although intermittent bleeding and soreness of the element were present. Dysmenorrhoea, dyspareunia, intermittent pelvic pain, and three years of infertility were noted...

Cutaneous endometriosis is defined by the presence of endometrial glands and/or stroma in skin and represents less than 1% of all ectopic endometrium. Cutaneous endometriosis is classified as primary and secondary. Primary cutaneous endometriosis appears without a prior surgical history and secondary cutaneous endometriosis mostly occurs at surgical scar tissue after abdominal operations. The most widely accepted pathogenesis of secondary endometriosis is the iatrogenic implantation of endometrial cells after surgery, such as laparoscopic procedures...
