    TLDR Brazilian patients with inflammatory bowel disease have a high rate of skin problems compared to healthy people.
    The cross-sectional study investigated the prevalence of skin lesions in 70 Brazilian patients with inflammatory bowel diseases (IBD), including 50 with ulcerative colitis and 20 with Crohn's disease, compared to a control group of 50 healthy individuals. The results showed that 95.7% of IBD patients had skin lesions, significantly higher than the 88% in the control group (p=0.001). Specific skin conditions such as alopecia, xerosis, striae, and acne were more prevalent in the IBD patients, with alopecia being more common in females (p=0.01). Two male patients, one with each type of IBD, had pyoderma gangrenosum, while erythema nodosum was not observed in either group. This indicates a high prevalence of skin lesions among Brazilian IBD patients, with certain conditions being more frequent in this population compared to healthy individuals.
