Nasal-type extranodal natural killer/T-cell lymphoma (ENKTCL) is a rare disease with a poor prognosis. It has features similar to other granulomatous and infectious diseases of the nose and paranasal sinuses, which can make diagnosis challenging and delayed. We present a case of 38-year-old man who was admitted to the hospital on three occasions over a 3-month period for right periorbital erythema, nasal congestion and discharge. Following two separate surgical debridement and biopsies, ENKTCL was diagnosed and the patient was commenced on chemoradiotherapy. The case highlights the atypical nature of his presentation and the high degree of suspicion for a pathological process that must be maintained to formulate the diagnosis.

BACKGROUND: Perioperative antimicrobial therapy has demonstrated efficacy in reducing the rate of surgical site infections in clinical trials. With the emergence of antibiotic resistance, the risk of reaction, and the inevitable financial repercussions, use of prophylactic antibiotics is not a panacea, and their misuse may have considerable implications. The aim of this study was to assess the use of antibiotics in the perioperative period in both general and vascular surgery procedures. METHODS: A prospective study was undertaken of 131 patients with a mean age of 43 years (range one month-88 years), of whom 68 (51%) were male, who underwent twenty-seven different general or vascular surgery procedures over a four-week period. Each patient was evaluated from the time of antibiotic commencement through their operative procedure until the treatment was discontinued. RESULTS: A total of 73 patients (54%) received ten antibiotics, with 71 (97%) of these uses being prophylactic. Of the 15 appendectomies performed for uncomplicated appendicitis, the mean number of prophylactic antibiotic doses was 5.3 (range 1-12). Where they were documented, written postoperative directives were not adhered to in 18/27 prescriptions (66%). CONCLUSION: This study has demonstrated a lack of adherence to guidelines in the perioperative administration of antimicrobial agents. In addition, it calls attention to the economic implications of unnecessary prophylaxis.
