We report the case of a female patient with double endocrine neoplasia type 1. Echoendoscopy (EUS) revealed two nodular hypoechoic lesions ([Fig. 1]), with a color Doppler hypervascular pattern located in the pancreas. We carried out an EUS-guided fine-needle aspiration (FNA) biopsy [1] ([Fig. 2]), which showed a neuroendocrine islet tumor in the pathology report 2 weeks later. Tumor sizes were 11 and 7 mm respectively.
