Biliopancreatic diversion (BPD) is a malabsorptivebariatric procedure can lead to the development of several nutritional complications, including fat-soluble vitamins deficiencies. Routine supplementation with vitamins and trace elements and a close follow-up long-term can prevent these nutritional risks. Vitamin A participates in ocular metabolism, epithelial differentiation, growth, and embryogenesis. Have been described several cases of ophthalmological and fetal complications associated with vitamin A deficiency in patients who have undergone BPD. Few information exists in literature about dermatologic manifestations that may occur in these patients. Phrynoderma is a type of follicular hyperkeratosis located on the extensor surfaces of the extremities whose main cause is vitamin A deficiency. We report an exceptional case of severe cutaneous and ocular complications in a patient who had undergone BPD with poor adherence to treatment and postoperative follow-up. Our patient presented simultaneously the characteristic skin lesions of phrynoderma with nytalopia and xerophthalmia in a setting of low serum levels of vitamin A. Treatment with high doses vitamin A obtained the resolution of both processes. We review and discuss the relationship between phrynoderma, malnutrition and vitamin A deficiency.
