Third reported case of rare necrolytic migratory erythema associated with bacteraemia due to severe zinc deficiency after revisional Roux-En-Y gastric bypass: case report and literature review

Introduction Obesity is a risk factor for zinc deficiency. After bariatric surgery, non-compliance to diet/vitamin supplements, surgical complications leading to vomiting/diarrhea, poor follow-up and malabsorption can precipitate or exacerbate pre-existing zinc deficiency. Case report We report a patient with rare necrolytic migratory erythema associated with bacteraemia due to severe zinc deficiency after revisional Roux-en-Y gastric bypass (following primary laparoscopic sleeve gastrectomy). Conclusion Bariatric teams should screen patients before bariatric surgery for nutritional deficiencies and continue surveillance of their nutritional status after surgery. They should maintain a high index of suspicion for zinc deficiency in patients with skin rash after bariatric surgery.
