Tumor Hypoglycemia

Introduction. Adrenocortical carcinomas (ACCs) are infrequently reported to present with severe hypoglycemia syndrome resulting from the secretion of insulin-like growth factor II (IGF-II) by tumor cells. Adrenocorticotropic hormone- (ACTH) independent hypercortisolism is the norm of hormonally active ACCs, but aberrant ACTH production by tumor cells can theoretically cause ACTH-dependent hypercortisolism. The purpose of this report was to present a case of an ACC manifested with the co-occurrence of two extremely rare presentations. Case Description. We present a rare case of a 43-year-old male patient admitted with recurrent episodes of severe non-ketotic and non-insulin-mediated hypoglycemia due to IGF-II mediated disease and ACTH-dependent Cushing’s syndrome. He was diagnosed with a diffusely disseminated adrenocortical carcinoma with immunohistochemistry of tumor cells showing focal ACTH immunostain positivity. Conclusion. Non-islet cell tumor hypoglycemia and ACTH-dependent Cushing’s syndrome are extremely rare presentations of an ACC, and co-occurrence of these entities in a single patient is never reported in the literature.

ABSTRACT Context The mechanism of IGF2 overexpression in non-islet-cell tumor hypoglycemia is not understood. Objective We investigated the imprinting control and promoter usage for IGF2 expression to identify a mechanism for increased IGF-II production in non-islet-cell tumor hypoglycemia. Patient and Methods A patient with metastatic hemangiopericytoma was studied. Tissue from the original hemangiopericytoma, metastatic tumor, and uninvolved liver was analyzed for IGF-II immunohistochemistry. IGF2, a paternally imprinted gene, shares a control region with maternally imprinted H19, a putative tumor suppressor. IGF-II and H19 mRNA expression was compared in metastatic tumor and uninvolved liver by quantitative RT-PCR. Imprinting of IGF2/H19 genes and IGF2 promoter usage in metastatic tumor was investigated by RT-PCR and sequence analysis, and the methylation pattern in the IGF2/H19 imprinting control region was analyzed. Results IGF-II protein expression was increased in metastatic tumor vs. uninvolved liver and original tumor. In the metastatic tumor, IGF-II mRNA was increased 60-fold, but H19 mRNA was comparable to uninvolved liver; loss of imprinting of IGF2, but not H19, was identified; no major change in methylation of the IGF2/H19 imprinting control regions was observed; and transcripts from four different IGF2 promoters were detected, compared to two in uninvolved liver. Conclusions IGF-2 overexpression, newly acquired in the metastatic tumor, was associated with loss of IGF2 gene imprinting and different promoter usage. The imprinting control mechanism governing the IGF2/H19 locus was intact, as evidenced by normal levels of H19, maintenance of H19 imprinting, and no major change in methylation of the imprinting control regions.

Abstract Background Splenic cord capillary hemangioma is a rare benign vascular lesion classified as a splenic hamartoma. On the other hand, non-islet cell tumor hypoglycemia (NICTH) is one of the rare causes of spontaneous hypoglycemia and is considered to be one of the paraneoplastic syndromes. To the best of our knowledge, this is the first reported case of a splenic cord capillary hemangioma with NICTH. Case presentation A 25-year-old male was referred to our hospital with hypoglycemia. Except for his low blood sugar, there were no abnormal findings from laboratory tests, which included an endocrinological examination. Enhanced computed tomography confirmed the presence of a solid mass measuring about 6 cm in the retroperitoneum, and a tumorectomy was performed. During this operation, it became clear that the tumor turned out to be a splenic parenchyma, and as a result, a total splenectomy was performed. Microscopically, we diagnosed this as a cord capillary hemangioma, and through immunohistochemistry, we found that some tumor cells were positive for insulin-like growth factor -II. Fortunately, the hypoglycemia-related symptoms disappeared after surgical resection was performed. The patient is still alive and well without evidence of local tumor recurrence 15 years after the operation. Conclusions Splenic cord capillary hemangioma, one of the types of splenic hamartomas, is a very rare benign vascular lesion and might be associated with hypoglycemia thought to be NICTH.
