Insulinoma Causing Liver Metastases 15 Years after Initial Surgery, Accompanied by Glomerulonephritis

الملخص EN

Insulinoma is a rare pancreatic endocrine tumor that is typically sporadic, solitary, and less than 2 cm in diameter.

Ninety percent of all insulinomas are benign.

Up to 10 percent are malignant and are usually larger in size.

We report a case of an unusual, not yet described association of two diseases: a malignant pancreatic insulinoma recurred as a multiple liver metastasis 15 years after the initial complete enucleation of a primary tumor with a histomorphological fairly benign outlook, accompanied by ANCA positive crescentic glomerulonephritis.
