[Non-functional or silent endocrine tumors of the pancreas. Apropos of a case of cystic form]. / Les tumeurs endocrines "non fonctionnelles" ou silencieuses du pancréas. A propos d'une observation à forme kystique.

The authors report a new case of silent cystic pancreatic endocrine tumour discovered by chance on abdominal ultrasonography. This tumour was treated surgically by simple enucleation-resection. On the basis of the histological appearance and the absence of metastases, this tumour was considered to be benign, but only the long-term course will confirm the diagnosis.
