Granular cell tumours (GCTs) are rare soft tissue tumours of neural origin. They have been reported in multiple anatomical sites. However, only 14 cases worldwide have been reported arising from the abdominal wall. While they can clinically manifest in a variety of ways, often they present as a small, slow-growing nodule with benign features. They can, however, be malignant, and in rare cases, they have been reported to metastasise. Here, we present a case of a rare abdominal wall GCT, which was managed with local excision. The purpose of this paper is to report the patient's clinical history, presentation, and surgical management, as well as to review the current literature to highlight the existence of this rare entity and the possibility that this may occur and should be considered a differential diagnosis in clinical practice., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Mangan et al.)

Low-grade appendiceal mucinous neoplasms (LAMNs) are rare and non-invasive tumors of the appendix, and their unexpected discovery during surgery can pose challenges to management. To date, only two cases pertaining to LAMNs without peritoneal spread in pregnancy exist in the literature. Here, we present a literature review of appendiceal mucinous neoplasms and discuss our management and operative approach to a large, incidental appendiceal mucinous neoplasm discovered during an emergency cesarean section of a 38-year-old female., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Bowles et al.)

Bezoars have different compositions and can be subdivided into trichobezoar, phytobezoar, pharmacobezoar, lactobezoar and food bolus. The reported incidence of bezoar is 0.4% with phytobezoar being the commonest. Rapunzel syndrome is an extremely rare complication when trichobezoar crosses the pylorus to enter the duodenum, ileum and colon. We present the case of a 29-year-old female with a one-week history of abdominal pain, anorexia, nausea, vomiting, constipation, lethargy and a one-year history of increasing abdominal mass. Physical examination revealed a 20 cm palpable mass extending from the left upper quadrant to the umbilicus. Laboratory investigations demonstrated iron deficiency anemia and CT showed two well-defined foci within the gastric lumen consistent with trichobezoars. She was managed conservatively during her hospital stay and discharged home with a plan for elective laparotomy. We present this case to discuss the management of trichobezoars and to highlight the importance of early recognition of recurrence to avoid severe complications., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Chin et al.)

Gallbladder volvulus (GBV) is an extremely rare disease, which presents similarly to acute cholecystitis. It has an incidence of less than 0.1% among urgent cholecystectomies and one in 356,000 hospital admissions. We report the case of a 92-year-old female with a three-day history of abdominal pain that had acutely worsened and localized to the right upper quadrant over the past 24 hours. Physical examination revealed a tender palpable mass in the right upper quadrant. Laboratory investigations demonstrated elevation of the white cell count and liver enzymes while CT abdomen showed a thick-walled gallbladder with an abrupt cut-off of the cystic duct suggestive of gallbladder volvulus. A laparoscopic cholecystectomy revealed a massively distended gangrenous gallbladder which has volved on the hepatocystic ligament. We present this case to demonstrate the radiological and intraoperative findings of GBV and to highlight the importance of early intervention to avoid life-threatening complications., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Chin et al.)

Portal vein thrombosis (PVT) is most commonly seen in people with predisposing conditions such as cirrhosis, hepatobiliary malignancies, infectious or inflammatory abdominal disease, or haematologic disorders. However, the incidence of idiopathic portal vein thrombosis in non-cirrhotic people is low and approximately 25% of existing cases have no identifiable cause. If untreated, complications can include portal hypertension, a cavernous transformation of the portal vein, varices, septic thrombosis, or intestinal ischemia. We report the case of a 27-year-old female who presented to her general practitioner with two weeks of epigastric pain. She was referred for an upper abdominal USG and CT imaging, which identified portal vein thrombosis with a normal appearance of the gallbladder, liver, and spleen. Thrombophilia screen was negative for Factor V Leiden and prothrombin mutations and lupus anticoagulant. The tumour markers alpha-fetoprotein and carcinoembryonic antigen were also within normal limits. The patient was started on rivaroxaban indefinitely following advice from a vascular surgeon and haematologist. Subsequent follow-up imaging also revealed cavernous transformation of the portal vein. We present this case to discuss the diagnosis, management and treatment of this patient and to review the current evidence available in managing idiopathic portal vein thrombosis in non-cirrhotic patients, especially the role of anticoagulation in chronic cases., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Ng et al.)

Dermatofibrosarcoma protuberans (DFSP) is an extremely rare sarcoma with an incidence between 0.8-5.0 cases per one million persons per year. DFSP accounts for less than 0.1% of all malignancies and approximately 1-6% of all soft tissue sarcomas. Only a few cases of DFSP have been found within the breast tissue. We report a case of DFSP in a 30-year-old female within the left breast. The sarcoma presented as a painless, rubbery, mobile lump that gradually increased in size. It was initially identified on an ultrasound scan and subsequently confirmed with MRI and core biopsy. DFSP is a rare condition and treatment guidelines are not well established. The current recommendation is for surgical excision with 2-cm margins. Mastectomy may be considered in some circumstances. In our case, the aim was for surgical resection with 2-cm margins at both breast tissue and skin, but insufficient margins were taken. The recommendation for re-excision of the inadequate margins was declined. It is uncertain what the implications of this are given the lack of research on DFSP in the breast. Therefore, close surgical surveillance will be imperative. We present this case to highlight the difficulties associated with the diagnosis, treatment, and management of DFSP due to the lack of literature on this disease., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Ng et al.)

Leptomeningeal metastases from the prostate are extremely rare, with few cases described in the medical literature (antemortem prevalence of less than 0.03%). Prostatic leptomeningeal metastases harbour a poor prognosis with a median survival after diagnosis of 15.7 weeks. We present the case of an 82-year-old male with a history of hormone-refractory prostate cancer who presented to the emergency department with neurological symptoms., Competing Interests: The authors have declared that no competing interests exist.

Acute acalculous cholecystitis is an uncommon disease in children and is usually associated with trauma, burns, and infections. Whereas acute acalculous cholecystitis is only seen in 10% of cholecystitis in adults, it is uncommon in the paediatric population. A seven-year-old male presented to the emergency department of a regional hospital with a 36-hour history of right-upper-quadrant abdominal pain. He had associated symptoms of anorexia, nausea, and vomiting. He was septic with raised white cell count and inflammatory markers. Diffuse gallbladder wall thickening without intraluminal sludge or calculi was seen on abdominal ultrasound. He was found to have a concurrent right-upper lobe pneumonia on further investigation. The patient was treated with antibiotics and responded well to supportive and conservative management with close radiological monitoring. Acute acalculous cholecystitis is associated with a high mortality rate (30%) and significant complications such as gangrene, empyema, and perforation in 40% of adult cases. Acute surgical management has been traditionally advocated, however, surgery is not without risks; studies have suggested that non-operative intervention may be appropriate for selected critically ill children with an underlying cause. Herein, we discuss the safe and effective conservative treatment of acute acalculous cholecystitis in lieu of operative management and highlight the importance of recognising this disease in paediatric patients with acute abdominal pain and coexisting infection., Competing Interests: The authors have declared that no competing interests exist.
