Recurrent Severe Hypoglycemia Secondary to Benign Phyllodes Tumor of the Breast: A rare case of Non-Islet Cell Tumor-induced Hypoglycemia (NICTH) / Journal of the ASEAN Federation of Endocrine Societies

ABSTRACT

@#Non-islet cell tumor-induced hypoglycemia (NICTH) secondary to phyllodes tumor is extremely rare but potentially life threatening if not treated promptly. We report a case of a 46-year-old Indian female without underlying diabetes mellitus who presented with a large breast tumor and recurrent severe symptomatic hypoglycemia. Investigations supported the diagnosis of NICTH. The hypoglycemia only resolved after corticosteroids and mastectomy. This case highlights the importance of considering NICTH in the evaluation of patients with voluminous tumor and hypoglycemia.
