The main features may include chronic or recurrent respiratory syndromes, pulmonary infiltrates on radiography, and even pulmonary hemosiderosis. However, gastrointestinal symptoms are rare in HS, which can lead to the misdiagnosis when the chief complaint is about gastrointestinal system. Here we report a case of HS complicated by severe hematochezia.
