Neuroendocrine tumors constitute a group of heterogeneous neoplasms, both those that are clinically asymptomatic and those which present with an array of symptoms. This variable clinical manifestation and unsatisfactory detection rate on diagnostic imaging make preoperative diagnosis particularly challenging. Insulinoma is a rare tumor originating from insulin-synthetizing pancreatic beta cells which clinically manifests hypoglycemia. The current study presents the case of a patient with a one month history of diabetes, and a tumor of the pancreatic head diagnosed at the Regional Hospital of Lomza (Lomza, Poland). The patient subsequently underwent surgery. The histological examination indicated insulinoma; islet cell tumor of the pancreas. The patient's postoperative period was uneventful and during two years of follow-up, the patient has remained in good health with completely controlled diabetes mellitus. The hereby-presented case of pancreatic insulinoma confirms this finding, as a correct diagnosis could only be established on the basis of pathomorphological examination. In addition, radical surgical resection is currently the only available treatment.

Article Synopsis
- Pancreatic neuroendocrine tumors (PNETs) are classified into functioning and non-functioning types, with non-functioning tumors being the most common and associated with higher morbidity due to potential tissue invasion and metastasis.
- Insulinoma is the most prevalent functioning PNET, leading to symptoms from excess insulin, while glucagonoma is another type that causes hyperglycemia from high glucagon levels, and the co-occurrence of both is extremely rare.
- A literature review identified 8 cases of patients with both insulinoma and glucagonoma from 1992 to 2021, highlighting the need for a multidisciplinary approach for effective diagnosis and treatment.

A 69-year-old female patient and a 70-year-old male patient were admitted to hospital with recurrent, severe hypoglycemic episodes and a typical manifestation of Whipple's triad. In the female, elevated levels of insulin, C‑peptide and pro-insulin together with pathological findings during a fasting test proved the presence of an insulinoma, which could be detected by Ga-68-DOTATOC-PET-CT in the pancreas. There was a very rare co-existence of a neuroendocrine Merkel cell carcinoma.

Multiple endocrine neoplasia type 1 (MEN1) is a rare syndrome of autosomal dominant inheritance defined by co-occurrence of two or more tumors originating from the parathyroid gland, pancreatic islet cells, and/or anterior pituitary. Insulinoma which has an incidence of 0.4% is a rare pancreatic neuroendocrine tumor.

Nonalcoholic fatty liver disease (NAFLD) is a serious health-related condition all over the world; the number of patients is increasing in Asian countries including Japan. Better understanding of its pathophysiology is required to develop effective therapeutics, as patients may go on to develop non-alcoholic steatohepatitis and hepatocellular carcinomas. While NAFLD is believed to be associated with metabolic risk factors such as obesity, diabetes, and dyslipidemia, its etiology remains largely unknown and the development or co-existence of NAFLD in patients with insulinoma has not been investigated.
