Polish Gastroenterology , 2012,
Abstract: Simple hepatic cysts are relatively common in the general population but rarely manifest clinically. Cysts causing clinical symptoms are usually large in size and affect patients over 50 years of age. The lesions are congenital and diagnosis is based on ultrasonography results supplemented by CT with contrast medium as required. Candidates for surgical treatment show clinical symptoms confirmed by initial diagnosis using imaging examination techniques, following exclusion of other potential causes of the disorder. Due to significant advancement of minimally invasive techniques, patients with hepatic cysts may be successfully treated using laparoscopy, which is nowadays a method of choice. A case of giant hepatic cyst managed using laparoscopy is presented below.

Abstract: The aim of this study was evaluation of some specific markers of hematopoietic and mesenchymal stem cell and in mesothelial cells of peritoneum. In order to investigate the plasticity of Mesothelial Cells (MC), cell population from peritoneal dialysis fluid of early stage non-peritonitis male patients with 35-40 years old were first screened. Then they were analyzed by cell culture, flow cytometry and immunophenotyping for dominant markers such as CD45 and CD34 (as hematopoietic stem cell marker), HBME-1 (as mesothelial cell marker) and cytokeratin 18 (as an epithelial marker). Our results showed MCs possess some identical markers to mesothelial and epithelial cells. Also both mesenchymal (CD34ˉ) and hematopoietic (CD45+) stem cell markers were detected in these cells. This study could change the previously assumed plasticity of mesothelial cells as progenitor cells and lead us to the definition of a new expression of surface markers of MCS.

Abstract: Introduction. A peritoneal inclusion cyst is a very rare mesenteric cyst of mesothelial origin usually asymptomatic. A rare case of an 82-year-old white Caucasian female with a femoral hernia containing a large peritoneal inclusion cyst, mimicking strangulated hernia, is presented herein. Case Presentation. The patient was admitted to our hospital suffering from a palpable groin mass on the right, which became painful and caused great discomfort for the last hours. Physical examination revealed a tender and tense, irreducible groin mass. An inguinal operative approach was selected and the mass was found protruding through the femoral ring. After careful dissection it turned out to be a large unilocular cyst, containing serous fluid, probably originating from the peritoneum. McVay procedure was used to reapproximate the femoral ring. Histologic examination showed a peritoneal inclusion cyst. Discussion. Peritoneal inclusion cysts are usually asymptomatic but occasionally present with various, nonspecific symptoms according to their size. Our case highlights that high index of clinical suspicion and careful exploration during repair of a hernia is mandatory in order to reach the correct diagnosis about hernia’s contents.

Our case highlights that high index of clinical suspicion and careful exploration during repair of a hernia is mandatory in order to reach the correct diagnosis about hernia’s contents. 1. Introduction A peritoneal inclusion cyst is a very rare mesenteric cyst of mesothelial origin occurring in the peritoneal cavity, mostly affecting women in the reproductive age. Unilocular peritoneal inclusion cysts are usually asymptomatic, but occasionally present with various, nonspecific symptoms, which makes correct preoperative diagnosis difficult [1]. They may be attached or lie free in the peritoneal cavity, and occasionally they may involve the round ligament simulating an inguinal hernia. Femoral hernias comprise 6–17% of abdominal wall hernias and usually contain abdominal viscera [2]. We present a rare case of an 82-year-old white female with a femoral hernia containing a large peritoneal inclusion cyst, mimicking strangulated hernia. 2. Case Presentation An 82-year-old white Caucasian female was admitted to our hospital suffering from a palpable groin mass on the right, which appeared two days ago, but for the last hours before admission it became painful and caused great discomfort. The mass was tender and tense on physical examination measuring at least 8?cm on diameter, and it was not reducible. The initial differential diagnosis was either a strangulated femoral or groin hernia. She had no history of other hernias and her laboratory findings were within normal range. Also no history of previous surgery, endometriosis,

Abstract: The aim of the study was to investigate the morphology of mesothelial cells of the peritoneum of patients with terminal renal failure (TRF), taken by the biopsy immediately before the onset of peritoneal dialysis (PD), and to compare it with the findings in patients with PD. The samples were prepared in the way standard for light microscopy and transmission electron microscopy. In patients with TRF intracytoplasmatic inclusions could be observed, unusual protrusions of mesothelial apical surfaces, deformation of mesothelial cells and their detachment from the basal membrane, as well as the dilatated cisternae of granulated endoplasmatic reticulum with filamentous structures in some of them. In patients on PD cytoplasmic protrusions of different shapes and contents were observed at the surface of mesothelial cells, multiplication of basal membrane, occurrence of young forms of mesothelial cells as well as the detachment of those cells from the basal lamina.

Abstract: Se presenta el caso de una mujer de 41 a os que consulta por dolor abdominal y pelviano de carácter sordo de 6 semanas de evolución sin compromiso del estado general. Refiere el antecedente de una histerectomía por mioma realizada hace 3 a os. La ecotomografía y la TAC de abdomen y pelvis revelan una lesión quística gigante de 15 x 8 x 12 cm que ocupa parte del abdomen y la pelvis. Luego de una resección parcial y marsupialización es referida a cirugía por recidiva precoz del tumor quístico. Es reintervenida, lográndose una extirpación completa más anexectomía bilateral con buena evolución posterior. El estudio histopatológico confirma el diagnóstico inicial de quiste mesotelial simple. La ubicación pelviana de la lesión, el comportamiento clínico (recidiva precoz con crecimiento rápido) y las dimensiones son más característicos de un mesotelioma quístico benigno. Sin embargo, el carácter unilocular permite catalogarlo como un quiste mesotelial de crecimiento excepcional. La distinción entre ambas entidades no es menor, toda vez que el mesotelioma quístico benigno tiene una recidiva alta y puede malignizarse We report a 41 years old women presenting with abdominal and pelvic pain lasting six weeks. She had a history of hysterectomy three years ago. Abdominal ultrasound and CAT scan showed a giant cystic lesion of 15 x 8 x 12 cm that occupied a great portion of the abdomen and pelvis. After a partial resection and marsupialization, she was refereed to surgery due to an early relapse of the cyst. She was operated again, performing a complete cyst excision and bilateral anexectomy, with a good postoperative evolution. Pathology confirmed the diagnosis of a simple omental cyst. The unilocular feature of the lesion is characteristic of omental cysts. However, due to the pelvic location and dimensions, the differential diagnosis must be made with benign cystic mesothelioma, that had a high rate of relapse and may become malignant

Abstract: Mesenteric cysts are uncommon benign abdominal lesions with no classical clinical features. The preoperative diagnosis requires the common imaging modalities but the final diagnosis is established only during surgery or histological analysis. The treatment of choice is complete surgical excision. We report an 18- year-old female with a non-specific abdominal pain and discomfort since 3 weeks. Her CT scan showed a huge cystic swelling, which necessitated surgical exploration. Preoperatively, a giant cyst was encountered with displacement of bowel loops. The cyst was completely removed and histology report confirmed mesenteric cyst without evidence of malignancy.

Abstract: We report the case of a 36-year-old woman who presented with signs and symptoms of an irreducible inguinal hernia. Surgical exploration revealed a mesothelial cyst of the round ligament of the uterus. Mesothelial cysts of the round ligament are rare lesions, frequently masquerading as inguinal hernias, and should be included in the differential diagnosis of any inguinal mass. Clinical findings are those of a groin mass, discomfort, and bulging. Ultrasound and CT scans often demonstrate an aperistaltic cystic mass. Definitive diagnosis is usually made intraoperatively and confirmed histopathologically. 1. Introduction Differential diagnosis of a groin mass includes inguinal and femoral hernias, lymphadenopathy, benign or malignant tumours, saphenous vein varicosities, femoral artery aneurysms, abscesses, dermoid, sebaceous and pilonidal cysts and cystic lymphangiomas. Sex-specific pathologies include an undescended testis or a hydrocele of the spermatic cord in males and cysts, varicosities and endometriosis of the round ligament or herniation of the ovary in females [1]. We present and discuss a case of a rare mesothelial cyst of the uterine round ligament misdiagnosed as irreducible inguinal hernia and review the relevant literature. 2. Case Presentation A 36-year-old, female, caucasian, and multiparous patient presented at the outpatient surgical clinic with a twelve-month history of a right inguinal bulge and discomfort, with progressive worsening of pain over the past 24 hours. Past medical and surgical history was unremarkable. On clinical examination, a relatively firm, smooth inguinal mass was revealed, roughly 4 × 2?cm, medial to Poupart’s ligament, tender to palpation, and protruding when the Valsalva manoeuver was performed. Bowel movements were normal, without vomiting, abdominal distention, or signs of intestinal obstruction. Laboratory tests, and plain abdominal radiographs were within normal range. A preoperative diagnosis of an irreducible right inguinal hernia was made, and the patient consented to surgical treatment. Under general anaesthesia, the right groin was explored. The superficial inguinal ring appeared normal. Following incision of the external oblique aponeurosis, the round ligament was found unusually thin, and a multilobular clear-fluid cystic lesion, approximately 4?cm in diameter, originating from the round ligament, was observed (Figure 1). The lesion was dissected and excised. A concurrent small direct hernia was repaired by the plug-and-patch tension-free technique. The deep inguinal ring was found normal on
