Jejunal gastrointestinal stromal tumour masquerading as an ovarian cancer: A case report.

A 60-year-old lady presented with lower abdominal discomfort and a huge palpable intra-abdominal mass for 4 months, with significant weight loss over half a year. Transvaginal ultrasonography and computed tomography (CT) abdomen showed a large right solid cystic mass likely ovarian in origin. The CA-125 was raised. With the provisional diagnosis of ovarian cancer patient underwent laparotomy at Hospital Umum Sarawak, Malaysia. However intraoperative findings showed that uterus and both ovaries were normal. The tumour was arising from the jejunum and adherent to the dome of the urinary bladder and right broad ligament. The tumour was resected and final diagnosis was jejunal gastrointestinal stromal tumour (GIST). We described this case which was misinterpreted as an ovarian cancer.

Right ureteric reconstruction with vascularised interpositional appendix graft in retroperitoneal leiomyosarcoma.

We present here a case of a 66-year-old lady who was diagnosed with right iliac fossa retroperitoneal leiomyosarcoma at Hospital Umum Sarawak. The challenge in this case was the extension of tumour with the involvement of her right ureter causing proximal hydroureter and hydronephrosis. After resection of tumour en-block with the involved segment of ureter, it was not possible to repair the ureteric defect directly. We used interpositional vascularized appendix graft to repair this large (7 cm) ureteric defect. We describe here this uncommon technique of ureter reconstruction.

Intestinal knotting: A case report and brief literature review.

Ileo-ileal knotting is a rare cause of intestinal obstruction. In this condition, one bowel loop makes a knot with an adjacent bowel loop, resulting in mechanical obstruction and even gangrene of the bowel. We present a case of a young girl with ileo-ileal knotting resulting in a closed-loop obstruction and gangrene of the small bowel loop. This is a difficult condition to diagnose; a high index of suspicion and early surgical intervention are essential to reduce morbidity and mortality.

Periampullary Carcinoma with Penile Metastasis.

Periampullary carcinoma metastases are usually located at regional nodes, adjacent organs, liver or lung. On the other hand, metastatic penile cancer is uncommon. Penile metastasis usually originates from pelvic region with prostate and bladder being the most frequent primary location. We present a very rare case of periampullary carcinoma with penile metastasis in a 49-year-old man. He initially presented with early ampullary type periampullary carcinoma and had pyloric preserving pancreatoduodenectomy and adjuvant chemotherapy. However, after six years of uneventful follow up, he presented with a penile lesion which was confirmed to be pancreatic metastasis. He was started on chemotherapy but passed away two months later. Ampullary carcinoma type of periampullary carcinoma usually presents early with favourable prognosis. However, tumour recurrence can present much later after definitive treatment and at a rare site such as penis with generally poor outcome.

Killian-jamieson diverticulum: the rarer cervical esophageal diverticulum.

Killian-Jamieson (K-J) diverticulum is a rare cervical oesophageal diverticulum, less commonly encountered compared with Zenker's diverticulum (ZD). We report a case of K-J diverticulum in a 52-year-old lady who presented with sensation of lump in the neck and food stuck in the throat of 5 years duration. Esophagogram showed a large rightsided pharyngoesophageal diverticulum which was confirmed on endoscopy. The patient underwent a diverticulopexy and recovered without complications. Her symptoms had improved. In this report, we review the literature and describe our surgical technique.
