Summary Pyoderma gangrenosum ( PG ) is a neutrophilic dermatosis of unknown aetiology. We report a 27‐year‐old male patient with diabetes, who presented with a nonhealing ulcer on the left leg, pruritic hyperpigmented papules distributed over the trunk and limbs, and chronic diarrhoea. He had eosinophilia, low haemoglobin and serum IgE levels, and raised erythrocyte sedimentation rate. Histopathology of the leg ulcer was consistent with the diagnosis of PG , while the histology of the hyperpigmented papule revealed tissue eosinophilia. Subsequent evaluation was conclusive of the diagnosis of PG , idiopathic hypereosinophilic syndrome ( IHES ) and selective IgE deficiency. Dexamethasone pulse therapy achieved resolution of the ulcer and reduction in the eosinophilia. Further evaluation for the persistent diarrhoea led to a diagnosis of lymphocytic colitis ( LC ), which responded to budesonide. To our knowledge, the association of PG with IHES , selective IgE deficiency or LC has not been previously reported.
