A 76-year-old Japanese man was transferred to our hospital to undergo rehabilitation after traffic accident-related injuries. Seven days post-admission, he presented with abdominal pain and an 8-cm lump in the right inguinal region. He was diagnosed with an incarcerated inguinal hernia and underwent elective surgery the day after manual reduction. He had a normal vermiform appendix which was observed to have adhered to the right indirect hernia sac. An appendectomy and hernia repair using lightweight mesh were performed. We discuss the surgical management of this rare incarcerated Amyand's hernia and the relevant literature.

Review
OBJECTIVE
Parasites and plant seeds may both be found in appendectomy specimens. Each plant seed has a different appearance and can thus exhibit wide variations under the microscope. Fragmented seeds may histologically mimic parasites. The differential diagnosis between seeds and parasites can be challenging in such cases. This study aimed to determine the incidence of parasites, seeds, and foreign bodies in appendectomy materials and highlight the most characteristic histopathological features associated with these structures.
MATERIAL AND METHOD
In this study, pathology slides of 9,480 patients, who underwent appendectomy between 2010 and 2021, were reviewed, and cases that contained parasites, seeds, or foreign bodies were identified. We reviewed the literature on seeds and parasites in appendectomy specimens.
RESULTS
Parasites were observed in 56 (0.6%) cases. Of these cases, 45 had Enterobius vermicularis (80%), and 11 had Taenia subspecies (20%). Plant seeds were observed in 47 cases (0.5%), and were macroscopically recognizable in 5 of them as olive, lemon, and cherry seeds. Parasites and seeds were usually observed in the lumen of appendix vermiformis, filled with abundant fecal materials.
CONCLUSION
Seeds are seen in approximately 0.5% of the appendectomy specimens. Though rarely seen, the fragmented seed appearance may cause diagnostic difficulties. In this context, the key morphological features of parasites and plant seeds outlined in this study may be helpful in their differential diagnosis.

BACKGROUND
Appendix neoplasms are rare tumors of the gastrointestinal system. Appendiceal adenocarcinoma, appendiceal mucinous neoplasm, and neuroendocrine tumors (NETs) are the most encountered appendix-related neoplasms. The patients are usually got diagnosed after histopathological examination. This study aimed to explore the epidemiology, pathological subtypes, and treatment modalities of appendix neoplasms.
METHODS
A retrospective examination was made with 2821 patients who underwent appendectomy between April 2010 and August 2020. Demographic, clinical, radiological, surgical findings, and histopathological results were collected from the patient files.
RESULTS
Appendix neoplasms were detected in 1.06% of the patients included in the study. The mean age was 44.6±17.5 (17-83) years. Eight NETs, seven adenocarcinomas, fourteen mucinous neoplasms, and one neuroma were diagnosed with patients.
CONCLUSION
Appendiceal neoplasms are generally asymptomatic and often diagnosed with postoperative histopathological ex-amination. If the result is adenocarcinoma, right hemicolectomy recommends. Treatment of NETs depends on factors such as tumor size, location, mesoappendix invasion, and lymph node involvement. In the presence of mucinous neoplasm, surgical intervention is determined according to the pathological subtype and involvement of mesoappendix. The need for additional surgical intervention or medical treatment for patients with tumor, histopathological results must be followed carefully after appendectomy.

Review
CONTEXT
The appendix gives rise to an array of epithelial neoplasms showing glandular or neuroendocrine differentiation, and some tumors with elements of both cell types. Although some appendiceal neoplasms resemble their counterparts in the small and large intestines (conventional adenocarcinoma and carcinoid tumor), the appendix also gives rise to relatively unique entities including mucinous neoplasms and goblet cell carcinoid tumors, which present a challenge in pathologic classification and clinical management.
OBJECTIVE
To review clinical and diagnostic issues for 3 pathologic types of epithelial neoplasms of the appendix: (1) adenocarcinoma, with specific focus on mucinous neoplasm; (2) goblet cell carcinoid tumor and associated adenocarcinoma; and (3) typical carcinoid tumor.
DATA SOURCES
Case-derived material and literature review.
CONCLUSIONS
The most important issue in pathologic assessment of epithelial tumors of the appendix is to understand the clinical implications inherent in the diagnosis.

PURPOSE Acute appendicitis is the most common cause of the acute abdomen requiring surgery. Although standard treatment has been surgery, it has been seen in recent years that treatment is possible with antibiotics and non-operative observation. In this study, our aim is to determine whether the CT findings in patients diagnosed with acute appendicitis can be used for directing treatment. METHODS A retrospective analysis was conducted on 138 patients with acute appendicitis who underwent CT between 2015 - 2019. In this study, medical treatment group (n = 60) versus surgical treatment group (n = 78) and successful antibiotic treatment group (n = 23) versus unsuccessful antibiotic treatment group (n = 14) were compared. Appendiceal wall thickness, appendiceal diameter, the severity of mural enhancement, intra-abdominal free fluid, the severity of periappendiceal fat stranding, size of pericecal lymph node, appendicolith, adjacent organ findings and the CT appendicitis score of groups were compared with Pearson Chi-square and Mann Whitney U tests. Multivariable logistic regression was used to identify predictors of surgical treatment, expressed as odds ratios (ORs) with 95% confidence intervals. Diagnostic efficacies of appendiceal diameter, the CT appendicitis score and developed model were quantified by ROC curves. RESULTS Appendiceal diameter (P < .001), adjacent organ findings (P = .041), the CT appendicitis score (P < .001), the severity of periappendiceal fat stranding (P = .002), appendicolith (P = .001) and intra-abdominal free fluid (P <0.001) showed statistically significant differences between the medical and surgical treatment groups. According to the logistic regression test, if the patients with appendiceal diameter ≥13mm (OR = 5.1, 95%CI 1.58 - 16.50), appendicolith (OR = 4, 95%CI 1.17 - 13.63) and intra-abdominal free fluid (OR = 3.04, 95%CI 1.28 - 7.20), surgeons should prefer surgical treatment. The AUCs for the CT appendicitis score, the appendiceal diameter and the model were 0.742 (95% CI 0,659 - 0,824), 0.699 (95% CI 0.613 - 0.786) and 0.745 (95% CI 0.671 - 0.819), respectively. As the successful and unsuccessful medical treatment groups were compared, the only significant parameter was the severity of mural enhancement (P = .005). CONCLUSION CT findings may be helpful in patients with uncomplicated acute appendicitis whose treatment surgeons are indecisive about. We can recommend surgical treatment in cases with appendix diameter ≥13mm, intraabdominal free fluid, appendicolith, high CT appendicitis score and severe mural enhancement.

Review
A 21-year-old female patient presented with vague lower abdominal pain associated with nausea since 2 days. On examination, she was tender in the right iliac fossa. Based on clinical presentation and radiological test finding, she was diagnosed as appendicitis and was subjected for diagnostic laparoscopy and appendectomy. Histopathology proved it to be a tubercular appendix, which is a rarely encountered entity. However, in a country like India, tuberculosis (TB) is highly prevalent; however, TB of appendix is rare and less known.

BACKGROUND
The propensity of Ascaris lumbricoides to wander leads to varied surgical complications in the abdomen. Wandering A lumbricoides may sometimes reach the vermiform appendix and its presence there may remain silent or incite pathology. Our aim was to study ascariadial appendicitis.
METHODS
Over a period of 3 years, we identified children who were found to have appendiceal ascariasis during surgery for different intestinal complications due to ascariasis. We studied the relationship between ascariasis and its lodgement inside the vermiform appendix in these patients. No preoperative diagnosis was made in this series.
RESULTS
We found 11 patients with appendiceal ascariasis. It was incidentally found that 8/11 (72.7%) patients had worms inside their vermiform appendix but not appendicitis, whereas the remaining three patients (27.2%) were found to have Ascaris-associated appendicitis. The characteristic finding in Ascaris-infested vermiform appendix was that the worm is positioned with its head at the base and its tail at the tip of the appendix.
CONCLUSION
Migration of A lumbrocoides inside the vermiform appendix is an incidental finding and tends to pursue a silent course in most patients. Only rarely does the presence of Ascaris inside the vermiform appendix cause appendicitis.
