[Clinical case of plurihormonal pituitary adenoma (STH/ACTH/TSH/FSH/LH-secreting), diagnostic pitfalls]

According to numerous studies, the most common pituitary tumors are prolactinomas, reaching 60% of all clinically significant adenomas, the next in order are non-functional pituitary adenomas, somatotropinomas, corticotropinomas and thyrotropinomas. Plurigormonal tumors occur in less than 1% of all pituitary adenomas. The most common form of mixed secretion adenoma in this patient population, derived from the Pit-1 cell line, produces various combinations of hormones: growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH). This article presents a patient with a plurihormonal two-component pituitary macroadenoma with a rare and exceptional combination of secreted hormones - GH / adrenocorticotropic hormone (ACTH) / TSH / follicle-stimulating hormone (FSH) / luteinizing hormone (LH) with minimal nonspecific clinical manifestations such as diabetes mellitus and poorly controlled arterial hypertension.
