RESUMO

BACKGROUND: Penile inversion vaginoplasty still remains the gold standard in genital gender affirming surgeries in transwomen. However, insufficiency of the penile skin due to either radical circumcision or puberty blockers presents great challenge in vaginal reconstruction. Peritoneal pull-through vaginoplasty is well known technique for the treatment of vaginal absence in cis-woman due to vaginal agenesis or trauma. OBJECTIVE: We describe our laparoscopy assisted technique of using peritoneal flaps for neovaginal construction in male to female gender affirming surgery METHODS: In period from March 2016 to June 2021, 52 transwomen, aged from 19 to 52 years (mean 27) underwent laparoscopy assisted peritoneal pull-through vaginoplasty. Indications were genital skin insufficiency (radical circumcision in 16, scrotal skin insufficiency in 3 and lichen sclerosis in 3 cases) and prepubertal blockers in 22 and 17 cases, respectively. In remaining 13 candidates, peritoneal pull-through vaginoplasty was preferable method of choice. Two peritoneal flaps are harvested from posterior bladder wall and anterior rectosigmoid peritoneum, using laparoscopy approach. Vaginal channel is created by combined perineal and laparoscopy approaches. Good vascularized peritoneal flaps are maximally mobilized and pulled-through to be joined with inverted penile skin. Peritoneal flaps are joined laterally to create neovagina. Gender affirming surgery is completed with reconstruction of external female genitalia, clitoris, labia minora and majora, and urethra. Vaginal packing is placed for 7 days postoperatively and followed by proper vaginal dilation for the first 12 months postoperatively. RESULTS: Follow-up ranged from 6 to 69 months (mean 29 months). Complications occurred in 7 cases: 3 had prolonged hematoma of the labia majora, one had neovaginal introitus dehiscence and one had superficial necrosis of the left labia majora. None of the complications required additional surgeries. The depth of the neovagina at the control check-up in 6 months after surgery was 14.7 ± 0.5 cm, while width was about 3.4 ± 0.4 cm. Majority of patients (≈96%) were satisfied with the new genitalia, sensitivity, lubrication and possibility of engaging in sexual intercourse according to self-reports. One patient required reduction of the size of her clitoris because of hypersensitivity and the other one requested laser treatment of the incisional scars. CONCLUSION: Although known for quite a long time in vaginal reconstruction for cis-women with vaginal agenesis and different forms of vaginal absence, peritoneal pull-through vaginoplasty offers promising outcomes in transgender women, as an option that will give self-lubricating neovagina, with insignificant scarring and complications and high degree of patient's satisfaction.

RESUMO

BACKGROUND: Spleen artery aneurysm represents the most common visceral aneurysm and the third most common splanchnic aneurysm. Most patients have no symptoms and are diagnosed as a part of other diagnostic focuses and examinations. Greater prevalence and application of modern diagnostic and imaging procedures has resulted in greater detection of this disease. RESULTS: We present two patients with splenic artery aneurysms localized in the splenic hilum, who auspiciously underwent laparoscopic splenectomies with the use of hem-o-lock clips in the vascular hilum without complications. Both postoperative courses were uneventful. At six months follow up, both patients are asymptomatic. CONCLUSION: These two cases showed that in addition to the numerous advantages of minimally invasive approaches for treating splenic arterial aneurysms, there is a possibility to improve laparoscopic technique in terms of safety and economic reasons by using hem - o - lock clips as a hemostatic technique for the vascular elements of the spleen hilum.

RESUMO

Isolated hydatid cysts of the pancreas are rare lesions, even in endemic regions. In this report, we present the case of a 76-year-old patient who was admitted to our clinic with a diagnosis of a cystic lesion in the tail of the pancreas. On preoperative computed tomography (CT) and magnetic resonance (MR) examination, the cyst was characterized as a mucinous cystadenoma. A laparoscopic distal pancreatectomy followed. A histopathological examination revealed a large hydatid cyst in the tail of the pancreas.

RESUMO

Although profoundly studied, etiology of pancreatic cancer (PC) is still rather scarce. Some of established risk factors of PC are connected to an increased cadmium (Cd) body burden. Hence, the aim of this study was to investigate the role of this environmental pollutant in PC development by conducting human observational, experimental and in vitro studies. The case-control study included 31 patients with a histologically based diagnosis of exocrine PC subjected to radical surgical intervention as cases and 29 accidental fatalities or subjects who died of a nonmalignant illness as controls. Animal study included two treated groups of Wistar rats (15 and 30 mg Cd/kg b.w) and untreated control group, sacrificed 24 h after single oral exposure. In in vitro study pancreas hTERT-HPNE and AsPC-1 cells were exposed to different Cd concentrations corresponding to levels measured in human cancerous pancreatic tissue. Cd content in cancer tissue significantly differed from the content in healthy controls. Odds ratio levels for PC development were 2.79 (95% CI 0.91-8.50) and 3.44 (95% CI 1.19-9.95) in the third and fourth quartiles of Cd distribution, respectively. Animal study confirmed Cd deposition in pancreatic tissue. In vitro studies revealed that Cd produces disturbances in intrinsic pathway of apoptotic activity and the elevation in oxidative stress in pancreatic cells. This study presents three different lines of evidence pointing towards Cd as an agent responsible for the development of PC.

RESUMO

OBJECTIVES: Laparoscopic splenectomy became the standard surgical procedure in the 1990s. The goal of this study was to analyze the outcome of the patients who underwent laparoscopic splenectomy for the benign hematologic diseases of the spleen and compare its results with open splenectomy. MATERIAL AND METHODS: The study was conducted as a retrospective cohort study analyzing and comparing the data obtained from 196 patients' case records in the Clinic for Digestive Surgery, Clinical Center of Serbia, for the benign disorders of the spleen, divided into two groups: patients operated with laparoscopic technique and patients in whom classic splenectomy was performed. The analyzed parameters were divided into three groups as preoperative, intraoperative and postoperative. RESULTS: In the laparoscopic splenectomy group, less intraoperative blood loss, lower incidental intraoperative complications and a shorter duration of surgery were recorded. The incidence of postoperative complications and reoperations was higher in the group of classically operated patients. Postoperative recovery, expressed by the duration of postoperative abdominal drainage, recovery of intestinal peristalsis and length of postoperative hospitalization, was significantly shorter in the laparoscopic group. CONCLUSION: Laparoscopic splenectomy is an effective and safe surgical procedure in the treatment of many benign diseases of the spleen. Improvement of the laparoscopic technique of surgical teams and technical improvement of the laparoscopic equipment can lead to even wider application of laparoscopic splenectomy as standard operative procedure, and thus to safer and better quality treatment of patients with wider spectrum diseases of the spleen.

RESUMO

PURPOSE: The primary aim of this study was to evaluate the benefit of extended lymphadenectomy in pancreaticoduodenectomy (PD) and to estimate its impact on long-term survival in patients with pancreatic head carcinoma. Secondary endpoints included perioperative mortality, postoperative morbidity and predictors of survival in patients undergoing standard versus extended lymphadenectomy for pancreatic head carcinoma. METHODS: From January 2007 to December 2010, 60 patients with potentially resectable pancreatic head carcinoma were operated using pylorus-preserving pancreatoduodenectomy (PPPD) at the Clinic for Digestive Surgery, Clinical Center of Serbia, Belgrade. Intraoperatively patients were randomly stratified into two groups: the first group (N1=30) underwent PPPD with standard lymphadenectomy whilst the second group (N2=30) was operated with PPPD with extended lymphadenectomy. None of the patients received adjuvant treatments. RESULTS: The number of retrieved lymph nodes, mean operating time and postoperative hospital stay were greater in patients with extended lymphadenectomy . Cox regression analysis showed that stage and lymph node metastasis were independent prognostic factors for survival. CONCLUSION: Extended lymphadenectomy in PPPD did not improve long-term survival in patients with resectable pancreatic head carcinoma and led to comparable and similar morbidity and mortality rates to those after standard lymphadenectomy.

RESUMO

INTRODUCTION: Autoimmune cholangitis or immunoglobulin G4-associated cholangitis (IAC) has been recently regarded as a new clinical and histopathological entity and is a part of a complex autoimmune disorder--IgG4-related systemic disease (ISD). ISD is an autoimmune disease with multi-organic involvement, characterized with IgG4-positive plasmocytic infiltration of various tissues and organs with a consequent sclerosis, which responds well to steroid therapy. Most commonly affected organs are the pancreas (autoimmune pancreatitis, [AIP]) and the common bile duct (IAC). IAC and cholangiocarcinoma (CCA) share many clinical, laboratory and imaging findings. CASE OUTLINE: We present a case of a 60-year-old male with a biliary stricture of a common bile duct, which was clinically considered as a bile duct carcinoma and treated surgically. Definite histopathological findings and immunohistochemistry revealed profound chronic inflammation, showing lymphoplasmacytic IgG-positive infiltration of a resected part of a common bile duct, highly suggestive for the diagnosis of IAC. In addition, postoperative IgG4 serum levels were also increased. CONCLUSION: It is of primary clinical importance to make a difference between IAC and CCA, in order to avoid unnecessary surgical intervention. Therefore, IAC should be considered in differential diagnosis in similar cases.

RESUMO

Primary retroperitoneal mucinous cystic tumors are extremely rare. These tumors can be classified as a primary retroperitoneal mucinous cystadenoma with or without borderline malignancy or primary retroperitoneal mucinous cystadenocarcinoma. The most common of these is primary retroperitoneal mucinous cystadenoma, which almost always occurs in female patients; only ten cases have been reported in males. The most common clinical findings for this tumor type include nonspecific abdominal pain and a palpable abdominal mass. A definitive diagnosis is usually obtained from histopathology after surgical excision. Here, we report the case of a 60-year-old female patient who complained of abdominal pain that had been present for 3 mo and presented with a palpable abdominal mass. Multidetector computed tomography scanning revealed a large, unilocular cystic mass in the left retroperitoneal space. Surgical intervention was performed and the tumor was completely removed. Histopathologic examination confirmed that the tumor was a primary retroperitoneal mucinous cystadenoma. Two years after surgery, the patient remains disease free.

RESUMO

AIM: To determine predictors of clinically relevant pancreatic fistulas (CRPF) by measuring drain fluid amylase (DFA) in the early postoperative period. METHODS: This prospective clinical study included 382 patients with periampullary tumors that were surgically resected at our department between March 2005 and October 2012. A cephalic duodenopancreatectomy (DP) was performed on all patients. Two closed suction drains were placed at the end of the surgery. The highest postoperative DFA value was recorded and analyzed during the first three postoperative days and on subsequent days if the drains were kept longer. Pancreatic fistula (PF) was classified according to the International Study Group of Pancreatic Fistula (ISGPF) criteria. Postoperative complications were defined according to the Dindo-Clavien classification. All data were statistically analyzed. The optimal thresholds of DFA levels on the first, second and third postoperative days were estimated by constructing receiver operating curves, generated by calculating the sensitivities and specificities of the DFA levels. The DFA level limits were used to differentiate between the group without PF and the groups with biochemical pancreatic fistula (BPF) and CRPF. RESULTS: Pylorus-preserving duodenopancreatectomy was performed on 289 (75.6%) patients, while the remaining patients underwent a classic Whipple procedure (CW). The total incidence of PF was 37.7% (grade A 22.8%, grade B 11.0% and grade C 3.9%). Soft pancreatic texture (SPT) was present in 58.3% of patients who developed PF. Mortality was 4.2%. The median DFA value on the first postoperative day (DFA1) in patients who developed PF was 4520 U/L (range 350-99000 U/L) for grade A fistula (BPF) with a SPT and a diameter of the main pancreatic duct (MPD) of ≤ 3 mm. For grade B/C (CRPF), the median DFA1 value was 8501 U/L (range 377-92060 U/L) with a SPT and MPD of ≤ 3 mm. These values were significantly higher when compared to the patients who did not have PF (122; range 5-37875 U/L). The upper limit of DFA values for the first 3 postoperative days in the examined stages of PF were: DFA1 1200 U/L for the BPF and CRPF; DFA3 350 U/L for BPF and DFA3 800 U/L for CRPF. The determined values were highly significant and demonstrated a reliable diagnostic test for both BPF and CRPF. CONCLUSION: DFA1 ≥ 1200 U/L is an important predictive factor for PF of any degree. The trend of DFA3 (decrease of < 50%) compared to DFA1 is a significant factor in the differentiation of CRPF from transient BPF.

RESUMO

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) are rare and account for 0.1%-3% of all gastrointestinal neoplasms. GISTs are most commonly located in the stomach (60%) and 20%-25% are malignant, with metastases involving the peritoneum or the liver. Cystic liver metastases are extremely rare. Only two previous cases of patients with cystic liver metastases, prior to treatment with imatinib mesylate, have been described so far. CASE REPORT: We reported a 52-year-old woman presented with a history of abdominal fullness and discomfort. Clinical examination revealed two palpable masses, first in the right upper abdomen and second left to the umbilicus. Examinations revealed 4 cystic metastases in the liver, 3 in the right lobe (including a huge one measuring 20.5 x 16 cm), and 1 in the left lobe, together with a primary tumor on the greater curvature of the stomach. Gastric tumor was removed with a Billroth II gastrectomy. Partial excision of the largest liver metastasis was performed for histopathology. Immunohistochemistry confirmed the diagnosis of a GIST in both tissue samples. After an uneventful recovery the patient was commenced on imatinib mesylate therapy. The patient remainsed symptom-free at 24 months follow-up. CONCLUSION: This was the third reported case of gastric GIST with giant cystic liver metastases present prior to treatment with imatinib mesylate. Although extremely rare, GISTs may present with cystic liver metastases prior to treatment with imatinib mesylate, and should be considered in the differential diagnoses of patients with liver cysts of uncertain aetiology.

RESUMO

BACKGROUND/AIM: The aim of this study was to evaluate the clinical reliability of the immunoscintigraphy with radiolabeled monoclonal antibodies for the detection of metastases and recurrences of rectal carcinomas. METHODOLOGY: A total of 65 patients underwent immunoscintigraphy with radiolabeled monoclonal antibodies. Indication for that examination was suspicious rectal cancer or suspicious rectal cancer recurrence and/or metastases. RESULTS: The method proved to have 92.7% sensitivity, specificity 83.3%, positive predictive value 90.5%, negative predictive value 87.0% and accuracy 89.2%. There was a statistically significant relationship between immunoscintigraphy findings and rectoscopy findings (rs=0.415, p=0.013), as well as significant relationship between immunoscintigraphy findings and US findings (rs=0.332, p=0.001). Tumor marker levels were in positive correlation with findings of immunoscintigraphy (rs=0.845, p=0.001), especially raised CEA level (rs=0.816, p=0.004). Patients with higher CA19-9 level had higher Duke's stage (p=0.025). CONCLUSIONS: We can conclude that immunoscintigraphy can be helpful in the detection of metastases and recurrences of colon carcinomas.

RESUMO

BACKGROUND/AIMS: The aim is to compare the radionuclide (DC) and ultrasonographic (US) method in the assessment of gallbladder (GB) motility. METHODOLOGY: The study was performed in 15 controls (C), 10 patients with acute cholecystitis (AC), 20 patients with chronic acalculous cholecystitis (CAC), 26 patients with chronic cholecystitis with calculosis (CCC) as well as in 15 patients with GB dyskinesia (D). GB emptying period (EP), ejection fraction (EF) and ejection rate (ER) were estimated with dynamic cholescintigraphy (DC) and US. RESULTS: The DC and US finding in the patients with AC was typical in all the patients, i.e. GB was not visualized at all on DC, while on US, stone was visible in the cystic duct. There were significant differences (p<0.05) between the EF and ER values obtained between C and the three groups of patients CAC, CCC and D, using both methods. However, there were no significant differences in EF, EP and ER values among CAC, CCC and D (p>0.05). There was also high correlation between the results obtained with both methods in all the groups of patients studied. CONCLUSIONS: The results obtained by both methods are valuable for the assessment of GB motility. Although there are no significant differences and there is a high correlation between the values, radionuclide method is more precise, because it can register motility continuously.

RESUMO

INTRODUCTION: Glucagonomas are rare, frequently malignant tumours, arising from the Langerhans' islets of the pancreas. They usually secrete large amounts of glucagon that can cause a characteristic "glucagonoma syndrome", which includes necrolytic migratory erythema, glucose intolerance or diabetes, weight loss and sometimes, normochromic normocytic anaemia, stomatitis or cheilitis, diarrhoea or other digestive symptoms, thoromboembolism, hepatosplenomegaly, depression or other psychiatric and paraneoplastic symptoms. In certain cases, some or all glucagonoma symptoms may appear late, or even may be completely absent. CASE OUTLINE: The authors present a 43-year-old woman in whom an investigation for abdominal pain revealed a tumour of the body of the pancreas. During operation, the tumour of the body of the pancreas extending to the mesentery measuring 85 x 55 x 55 mm was excised. Histology and immunohistochemistry showed malignant glucagonoma, with co-expression of somatostatin in about 5% and pancreatic polypeptide in a few tumour cells. The recovery was uneventful. The patient stayed symptom-free with no signs of local recurrence or distant diseases 15 years after surgery. CONCLUSION: Glucagonoma syndrome may be absent in glucagonoma tumour patients so that in unclear pancreatic tumours the clinician should frequently request the serum hormone level (including glucagon) measurement by radioimmunoassay and the pathologist should perform immunohistochemistry investigation. Those two would probably result in discovery of more glucagonomas and other neuroendocrine tumours without characteristic clinical syndromes.

RESUMO

Somatostatinomas are extremely rare neuroendocrine tumors of the gastrointestinal tract, first described in the pancreas in 1977 and in the duodenum in 1979. They may be functional and cause somatostatinoma or inhibitory syndrome, but more frequently are non-functioning pancreatic endocrine tumors that produce somatostatin alone. They are usually single, malignant, large lesions, frequently associated with metastases, and generally with poor prognosis. We present the unique case of a 57-year-old woman with two synchronous non-functioning somatostatinomas, one solid duodenal lesion and one cystic lesion within the head of the pancreas, that were successfully resected with a pylorus-preserving Whipple's procedure. No secondaries were found in the liver, or in any of the removed regional lymph nodes. The patient had an uneventful recovery, and remains well and symptom-free at 18 mo postoperatively. This is an extremely rare case of a patient with two synchronous somatostatinomas of the duodenum and the pancreas. The condition is discussed with reference to the literature.

RESUMO

BACKGROUND/AIMS: The aim of the study was detection of abdominal infections by 99mTc- antigranulocyte antibodies. METHODOLOGY: Total of 36 patients with clinical suspicion on abdominal or gastrointestinal infections was investigated. RESULTS: There were 23 true positive (TP) findings (one pulmonary abscess, 2 subhepatic abscesses after surgery, 2 perianal fistula, 2 chronic and 4 acute appendicitis, 5 abdominal and 3 pelvic abscesses, 3 M. Crohn, one ulcerative colitis), 9 true negative (TN) (3 tumors of the coecum, 2 tumors of papilla Wateri, 2 gastric carcinoma, 2 colon carcinoma), and 4 false negative (FN) (2 abscesses subphrenic and 2 enterocolic fistula). False positive (FP) findings were not observed. The smallest lesion found was 19x18 mm. SPECT increased the number of TP findings from 17 to 23. Fifteen of 23 infectious of inflammatory lesions could be detected in the early scan. Sensitivity was 85%, specificity 100%, positive predictive value 100%, negative predictive value 69% and accuracy 89%. CONCLUSION: According to the present results, scintigraphy with 99mTc antigranulocyte antibodies is a useful method for detection and assessment of exact localization abdominal infections, which is very important for the prompt and appropriate therapy.

RESUMO

INTRODUCTION: Actinomycosis of the caecum is a rare, but most frequently an abdominally localized disease. It often simulates inflammatory malignancy, rarely a periappendicular abscess or Chron's disease and is only exceptionally the cause of intestinal obstruction or bleeding. CASE OUTLINE: The authors present a 35-year-old woman with an intrauterine device which remained inserted for over three years, causing the development of pain, fever, vaginal secretion and bleeding that continued even after the device was removed. Ultrasonography showed a tumorous mass of irregular form located close to the uterus, which after a few months developed into a colliquation filled with pus requiring incision. Bacteriological examination failed to show actinomycosis. Due to the tumorous lesions involving the terminal ileum, appendix, caecum, ascending colon and omentum, a right hemicolectomy was performed. Based on histolopathological findings of the resected sample the diagnosis of actinomycosis was made. Therefore, after surgery the patient began treatment with antibiotics resulting in full recovery. CONCLUSION: Although rare, actinomycosis of the caecum should be taken into consideration in the differential diagnosis of tumorous lesions of the caecoascending part of the colon, particularly if the tumour is associated with inflammation.

RESUMO

Ewing's sarcoma (ES) is a neoplasm of undifferentiated small round cells, which occurs in the bones and deep soft tissues of children and adolescents. We present a rare case of a 44-year-old woman with gastric ES presenting with epigastric pain and weight loss. Ultrasound and computed tomography scans indicated a solid/cystic mass in the pancreatic tail. At laparotomy, the tumor was found attached to the posterior surface of the stomach, completely free from the pancreas, with no lymphadenopathy or local metastases. The polynodal, partly pseudocystic, dark-red soft tumor was excised. Histopathology revealed an anaplastic small-round-cell tumor with strong membranous CD99 immunoexpression. Additionally, there was patchy immunostaining for S-100 protein, vimentin, protein gene product (PGP) 9.5 and neuron-specific enolase, and weak focal CD117 cytoplasmic immunoreactivity. The patient had no adjuvant chemotherapy; her postoperative recovery was uneventful, and she remains symptom-free, and without any sign of recurrence at 20 mo. To the best of our knowledge, this is only the third ever case of gastric ES.

RESUMO

BACKGROUND: Serous microcystic adenoma is a rare benign tumor of the exocrine pancreas originating from the ductal system and composed of a large number of small cysts covered by cuboid cells, filled with clear serous fluid and separated with fibrocolagenous stroma. Most frequently it appears in women in 7th and 8th decades, in the distal pancreas. It shows a very low malignant potential. In 2/3 of patients symptoms are uncharacteristic and in 1/3 they are absent When localised within the head of the pancreas it rarely causes an obstructive jaundice. CASE REPORT: We presented a 61-year-old female patient who for months had had mild and nonspecific abdominal symptoms developing to progressive obstructive jaundice. At surgery we revealed a rather large policystic mass of the head of the pancreas causing not only obstructive jaundice but also a venous stasis by compression and dislocation of the portomesenteric vein. The tumor was removed with pylorus preserving cephalic duodenopancreatectomy (Whipple's procedure modified by Longmire-Traverso). Histology confirmed serous microcystic adenoma of the pancreas. The postoperative recovery was uneventful and preoperative symptoms disappeared. CONCLUSION: Although very rare, serous microcystic adenoma might appear within the head of the pancreas and has to be taken into consideration in differential diagnosis of cystic lesions of the head of the pancreas. Very rarely the tumour might cause obstructive jaundice. Surgical resection, which might be demanding, leads to complete recovery.

RESUMO

BACKGROUND: Intraabdominal fat necrosis of the retroperitoneum, mesenthery and omentum is a frequent complication of acute pancreatitis. Very rarely, during the disease multiple aseptic subcutaneous fat necrosis, polyarthritis, polyserositis, vasculitis, subcutaneous nodi and eosinophylia, isolated or in combination, may appear. They are known as "pancreatic disease syndrome". CASE REPORT: We presented a female patient, 43-year-old, in whom in the course of acute interstitial biliary pancreatitis had occur red multiple localized aseptic necrosis of subcutaneous fat tissue of extremities appeared mostly around the talocrural and wrist joints requiring multiple incision, as well as aseptic elbow joints arthritis requiring puncture of one elbow joint. The symptoms were followed by a prolonged febrility that settled within several weeks. CONCLUSION: Localized disseminated fat necrosis around joints, arthritis of major joints, alone or with some of other symptoms of the "pancreatic disease syndrome" have to be considered as a probable sign of pancreatitis, even in the abscence of major abdominal symptoms.

RESUMO

Neurenteric cysts are extremely rare congenital anomalies, often presenting in the first 5 years of life, and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal abnormalities, but the latter may be absent in adults. Although usually located in the thorax, neurenteric cysts may be found along the entire spine. We present a 24-year-old woman admitted for epigastric pain, nausea, vomiting, low grade fever and leucocytosis. She underwent cystgastrostomy for a loculated cyst of the distal pancreas at the age of 4 years, which recurred when she was at the age of 11 years. Ultrasound and computer tomograghy (CT) scan revealed a 16 cm multiply 15 cm cystic mass in the body and tail of pancreas, with a 6-7 mm thickened wall. Laboratory data and chest X-ray were normal and spinal radiographs did not show any structural abnormalities. The patient underwent a complete cyst excision, and after an uneventful recovery, remained symptom-free without recurrence during the 5-year follow-up. The cyst was found to contain 1200 mL of pale viscous fluid. It was covered by a primitive single-layered cuboidal epithelium, along with specialized antral glandular parenchyma and hypoplastic primitive gastric mucosa. Focal glandular groups resembling those of the body of the stomach were also seen. In addition, ciliary respiratory epithelium, foci of squamous metaplasia and mucinous glands were present. The wall of the cyst contained a muscular layer, neuroglial tissue with plexogenic nerve fascicles, Paccini corpuscle-like structures, hyperplastic neuroganglionar elements and occasional psammomatous bodies, as well as fibroblast-like areas of surrounding stroma. Cartilagenous tissue was not found in any part of the cyst. Immunohistochemistry confirmed the presence of neurogenic elements marked by S-100, GFAP, NF and NSE. The gastric epithelium showed mostly CK7 and EMA immunoexpression, and the respiratory epithelium revealed a CK8 and CK18 immunoprofile without CK 10/13 positive elements, though neither CEA or AFP positive cells were found. To our knowledge, this is the first reported case of an abdominally located neurenteric cyst with no associated spinal anomalies.
