Plasmablastic lymphoma (PBL) is an uncommon human immunodeficiency virus (HIV)-associated lymphoma, with a predilection to develop in the oral cavity. It usually has a plasmablastic morphology with weak or no expression of B cell-associated markers. Among non-HIV patients, it tends to occur in the gastrointestinal (GI) tract, lymph nodes, and skin. We experience a 74-year-old male who presented with abdominal discomfort, altered bowel habit, loss of weight, and loss of appetite with a palpable abdominal mass. Upper endoscopy revealed multiple dish-like and raised nodular mass with a central ulcer in the stomach and duodenum. The histology was consistent with high-grade lymphoma of the plasmablastic type. The immunohistochemistry was positive for plasma cells marker of CD38 and CD138, but negative for the lymphocytic marker of CD45, as well as mature T and B cell marker of CD3 and CD20. Unfortunately, the patient succumbed due to sepsis without completion of his investigations and treatments.

Huge Retroperitoneal Cyst Masquerading as Ovarian Tumour: A Case Report.

Front Surg 2020 22;7:585411. Epub 2020 Oct 22.

Department of Surgery, Queen Elizabeth Hospital, Ministry of Health Malaysia, Kota Kinabalu, Malaysia.

Retroperitoneal cystic mass is a rare surgical condition that is often misdiagnosed preoperatively. Here, we report a case of a 56-year-old woman who presented with abdominal swelling for a 1-year duration, which was associated with lower abdominal pain for 6 months. Her abdominal radiograph showed a huge radiopaque lesion, and contrast-enhanced computed tomography scan of the abdomen reported it as a left ovarian serous cystadenoma causing local mass effect to the left ureter leading to mild left hydronephrosis. She underwent exploratory laparotomy and noted there was a huge retroperitoneal cystic mass. The histopathological assessment finding was consistent with a benign retroperitoneal cyst. This case report aims to share the rare case of primary retroperitoneal lesions, which can cause a diagnostic challenge preoperatively to all clinicians despite advanced achievement in medical imaging.

Trapped cystofix: Laparoscopic modality to untie.

Urol Case Rep 2021 Jan 9;34:101448. Epub 2020 Oct 9.

Suprapubic catheterization (SPC) is a temporary measure to relieve acute urinary retention (AUR). Despite being effective, it can lead to complications such as colon perforation, haematuria, and bladder wall spasm. We present a 52-year-old lady with cystofix for underlying urethral stricture presented with AUR. A new SPC was inserted to drain the urine. However, the SPC had looped and entangled with her cystofix, and laparoscopic removal of cystofix and insertion of a new SPC was done. In conclusion, trapped cystofix to the SPC tube is a potential complication during SPC insertion that can be avoided with appropriate care.

Vanek's tumor causing ileoileal intussusception in a middle-aged man.

Oxf Med Case Reports 2020 Jul 24;2020(7):omaa050. Epub 2020 Jul 24.

Intestinal obstruction is a common surgical emergency requiring urgent intervention. Small bowel obstruction secondary to intussusception is rarely encountered especially when inflammatory fibroid polyp (IFP) is the lead point. A 41-year-old gentleman with intestinal intussusception secondary to IFP presented to us with a classic symptom of intestinal obstruction. Computed tomography revealed a target or sausage-shaped soft tissue mass with a layering effect, which was confirmed by intraoperative findings. Histopathology was consistent with IFP and supported by immunoreactivity of CD34 and negative immunostaining for CD117. He recovered without any surgical complication or recurrence. Even intussusception can be managed via non-surgical technique in children; surgery is the mainstay of treatment in adults.

Giant submandibular sialolipoma masquerading as huge goitre: a case report.

BMC Surg 2020 Jun 11;20(1):130. Epub 2020 Jun 11.

Department of Otorhinolaryngology-Head and Neck Surgery, School of Medical Sciences, Universiti Sains Malaysia, Kota Bharu, Kelantan, Malaysia.

Background: Sialolipoma is a rare tumour which may arise from both major and minor salivary glands and has recently been described as a variant of salivary gland lipomatous lesions.

Case Presentation: We report a 54-year-old male who presented with a 7-year history of large right anterior neck swelling. He was clinically euthyroid and had no compressive or infiltrative symptoms. He sought medical attention due to the discomfort exerted by the weight of the mass and was keen for excision. The swelling appeared like a goitre but physical examination proved otherwise. Imaging was suggestive of a benign tumour arising from the right parapharyngeal fossa. The mass was surgically excised and was noted to be adherent to part of the submandibular gland. Histopathological examination revealed a new variant of benign adipocytic tumour of salivary gland or sialolipoma arising from the submandibular gland. Besides being the largest sialolipoma to be reported, there are also no reports of giant submandibular sialolipomas masquerading as a huge goitre in appearance.

Conclusion: Submandibular sialolipomas can present in really large sizes and appear as a giant goitre. It is important to differentiate between benign lipomas from liposarcomas and tailor the management accordingly. Surgical enucleation is the preferred choice of treatment for these benign tumours with low recurrence rates.

Emergency laparoscopic resection of spontaneous rupture of hepatocellular carcinoma: A case report.

Int J Surg Case Rep 2020 3;66:104-106. Epub 2019 Dec 3.

Department of Surgery, Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, Malaysia. Electronic address:

Introduction: Laparoscopic liver resection is currently performed as a therapeutic modality in hepatocellular carcinoma (HCC). In an emergency setting such as bleeding or rupture, however it has not been well documented.

Presentation Of Case: We describe a 55-year-old lady who presented to the emergency department with epigastric pain and symptoms of anaemia for one day duration. She was normotensive but tachycardic. Blood investigations revealed haemoglobin level of 6.5 g/dL and serum alpha-fetoprotein of 3136 g/dL. Contrast enhanced computed tomography scan revealed ruptured HCC of segment 2 and 3. She underwent emergency laparoscopic resection of the ruptured HCC. The postoperative recovery was uneventful and she was discharged well on postoperative day 7. Histology confirmed a 10 cm ruptured HCC with 3 mm tumour-free resection margin.

Discussion: Ruptured HCC is associated with a high mortality rate of 25-75 %. Traditional treatment involves initial stabilization and hemostasis through transarterial embolization followed by staged hepatic resection. However, laparoscopic liver resection has been shown to be superior than open surgery in terms of postoperative outcomes.

Conclusion: Laparoscopic resection of bleeding HCC is achievable and can be considered in the treatment algorithm of selected patients.
