Abstract:
A 19-year-old woman, who had been receiving hormone replacement therapy for 13 months before the diagnosis of mosaic Turner syndrome (46XXp-/45X), developed Crohn's colitis and erythema nodosum of the lower legs. Colonoscopy revealed an anal fistula and the presence of deep longitudinal ulcers with cobblestoning in the colorectum. Therapy with prednisolone and adalimumab was effective for the intestinal and skin lesions. To date, all seven case reports of Turner syndrome in Japan have also developed Crohn's disease after hormone therapy, suggesting a possible association of sex hormones in the pathogenesis.

The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
