Bariatric procedures have beneficial effects on metabolic disturbances, including dermatological conditions. Short-term skin reactions associated with sleeve gastrectomy are not described in the literature. We reviewed our database for patients who underwent bariatric surgery between May and October 2013 who reported a cutaneous rash during the short-term post-surgical period. Of a total of 195 patients, 8 (0.02 %) developed acute skin reactions during the first 3 months. Case 1 was compatible with reticulated papillomatosis. Case 2 was diagnosed as recurrent angioedema. Cases 3, 4, and 7 presented a cutaneous drug reaction to vitamin supplementation. Cases 5, 6, and 8 seemed to be secondary to xerosis and responded to lubrication. Acute cutaneous skin reactions after bariatric surgery are unusual. When they do occur, they appear to be benign conditions.
