#FIBROUS OBLITERATION APPENDIX SERIES#

The patient was discharged on postoperative day 7 without complications. The lesion was completely removed by laparoscopic endoscopic cooperative surgery.

However, in a series of follow-up endoscopies, the tumor was found to have grown in size, so it was surgically resected. The patient had no symptoms, and his laboratory test results were normal. This tumor was mistaken for a duodenal subepithelial tumor on preoperative upper GI endoscopy and endoscopic ultrasonography due to external compression of the GI wall. We report the case of a 72-year-old man with traumatic neuroma of the cystic duct after cholecystectomy. This is the first case report demonstrating that neuroma of the cystic duct can be incorrectly perceived as a duodenal subepithelial tumor by compressing the duodenal wall. In general, traumatic neuroma is a benign nerve tumor that results from postoperative nerve injury, occurring in the bile duct as one of the complications after cholecystectomy. Gastrointestinal subepithelial tumors (GSTs), incidentally detected during upper gastrointestinal (GI) endoscopy, may be lesions derived from the GI wall or may be caused by compression from external organs.

vermicularis infection appears to be an incidental finding in appendectomies rather than being a cause of appendicitis, it probably stimulates LH which may mimic acute appendicitis clinically. Fibrous obliteration was seen in 4 patients and it was correlated with age and eosinophil count in lamina propria p<0.05. Appendiceal lumen was completely obstructed in 12.5% (n=3), while it seemed narrow due to extensive LH in 3 (12.5%) cases. vermicularis was observed in the lumen, with acute appendicitis in 2 of them. Feces was present in the lumen in 79.1% of the patients (fecalith in 25%, soft feces in 29.1% and feces mixed with blood and/or suppuration in 25%). The patients with periappendicitis were significantly younger (mean age 4 vs. The most common findings were LH (100%), and congestion (91.7%) Acute inflammation was found in one third (n=8), with phlegmonous inflammation and/or periappendicitis in 4 of them. Female: male ratio was 1:1 and the median age was 12в™.34 years. vermicularis among 3222 appendectomies that were scanned for the study was 0.74% (24/3222). vermicularis infection of 24 cases were evaluated for the presence of acute inflammation, congestion, hemorrhage, perforation, lymphoid hyperplasia (LH), necrosis, granuloma, fecalith, obliteration, hyalinization, eosinophilic infiltration and mucosal architectural distortion. vermicularis infection.ДЄppendectomy materials with E. To evaluate the histopathological findings in appendectomy materials with E. Re-evaluation of 19 cases of abdominal neurogenic tumors demonstrated con-siderable variability in clinicopathologic characteristics depending on location, dimension and histological features. In all but 5 cases, the Ki67 proliferation index was в‰¤ 1%. All cases were S100-positive and CD117-negative most cases were negative for desmin, epithelial membrane antigen, smooth muscle actin and CD34. Gastrointestinal tract lesions were detected with endoscopy and extra-luminal lesions were detected with cross-sectional imaging. The majority of cases were asymptomatic at presentation, but the most frequent symptom was abdominal pain. Sizes of the tumors were variable, with a median diameter of 4 cm the two largest (> 10 cm) were schwannomas.

Final confirmed diagnoses were 12 schwannomas, 2 diffuse submucosal neuro-fibromatoses, 2 ganglioneuromas, 2 malignant peripheral sheath nerve tumors, and 1 mucosal Schwann cell hamartoma. The study included 19 cases of intraabdominal neurogenic tumors, representing 12 women and 7 men, between 18 and 86 years of age (median: 51 years). Clinical data and follow-up information were collected from the hospital records and the patients themselves, when available. Tissue microarrays were constructed for cases lacking necessary immunohistochemical studies. Diagnoses of neurogenic tumor cases were confirmed by two experts following review of the macroscopic, histological and immunohistochemical records along with findings from analysis of archived tissue sections for each included patient. To advance the overall knowledge on the histologic, immunohistochemical, clinical and radiologic characteristics of neurogenic tumors through this case series.ДЄn established database of a nationwide tertiary referral center, covering a 15-year period (20), was retrospectively re-evaluated. Reports on their incidence, pathological features and clinical characteristics are scarce. Neurogenic tumors are rare but represent an important consideration in the differential diagnosis of abdominal mesenchymal tumors.
