Necrotizing fasciitis (NF) is a deadly soft tissue infection causing a significant morbidity and mortality. Abdominal and chest wall NF are unusual. We describe a 49-year-old male with anterior abdominal wall NF secondary to per- forated gastric ulcer (PGU). He was admitted in septic shock presenting an abdominal wall NF with severe metabolic acidosis requiring dialysis and admission to the intensive care unit. There was a patch of gangrene with surrounding skin discoloration at lower quadrant of the abdominal wall. Local debridement was done without a preoperative computed tomography that was performed after surgery. Adequate source control was not achieved after the second surgery and the patient had worsened resulting to death. We describe this rare presentation of NF and discuss the issues learnt from this unfortunate event.
Introduction: Rectal schwannoma is a rare gastrointestinal mesenchymal tumour with only a few numbers of cases has been reported. It is predominant in the stomach and small bowel, but uncommon in the colon and rectum. Case description: A 74-year-old man presented with features masquerading as low rectal malignancy with a malignant looking pedunculated polyp measuring 10 x 8 cm on colonoscopy. Punch biopsy revealed a diagnosis of benign tumour of schwannoma. After failure of multiple attempts of endoscopic resection, a decision of transanal excision was made. The histopathological assessment was consistent with the preoperative diagnosis and supported by immu-nohistochemistry of S-100 protein. His postoperative recovery was uneventful as he was discharged on the following day. There is no evidence of tumour recurrence on follow up. Conclusion: A huge tumour of the rectum is not always malignant. However, patient with features of low rectal tumour warrants an immediate referral to the surgical team as this non-communicable disease is a public health concern. Preoperative diagnosis is paramount for a necessary surgical intervention.
