We report a case of Sweetʼs syndrome with parotitis complicated with ileal bleeding. An 84-year-old woman presented with tender swelling of both her cheeks and developed generalized erythematous papules and spiking fever. Skin biopsy revealed diffuse infiltration mostly comprising neutrophils with leukocytoclasia and no evidence of vasculitis. The histological and clinical findings were compatible with the diagnosis of Sweetʼ s syndrome. She developed hematochezia between the fifth and eighth day of hospitalization. After observing ileal bleeding using endoscopy, the bleeding was controlled by angiographic intervention using coil embolization. After improvements in her clinical and laboratory findings without the use of corticosteroids, she was discharged on the 42nd day after admission. After discharge, she developed stricture of the ileum as a complication of angiographic embolization and subsequently underwent surgical resection of the ileum. The resected ileum had no pathological evidence of another underlying disease, such as inflammatory bowel diseases or vasculitis. Although the etiology of Sweetʼs syndrome is diverse, cases involving parotitis and that develop ileal bleeding as a complication are rare. In this case, it is possible that antecedent parotitis resulted in the development of Sweetʼs syndrome. The histological findings of the ileum were non-specific;however, there appeared to be some association with Sweetʼs syndrome and ileal bleeding on its pathogenesis.
