Gigantism and acromegaly, usually caused by a pituitary adenoma linked innapropriate secretion of growth hormon (GH) are generally considered as very rare diseases, even if, regarding some authors, their cumulative prevalence is about 1/5000. Starting from the historical case of a giant from Liège we will describe the different types of GH pituitary adenomas and their physiopathology. We will overall discuss rare forms of inherited GH secreting pituitary adenomas like the FIPA (familial inherited isolated pituitary adenomas) and the X-LAG (X linked acrogigantism), both described in Liège, respectively in 2000 and 2014.

Context: Responses of GH-secreting adenomas to multimodal management of acromegaly varies widely between patients. Understanding the behavioral patterns of GH-secreting adenomas by identifying predictive factors of their evolution is a research priority. Objective: To clarify the relationship between adenoma T2-weighted signal on diagnostic MRI in acromegaly and clinical and biological features at diagnosis. Design: International, multicenter, retrospective analysis. Setting: 10 endocrine tertiary referral centers. Patients: 297 acromegalic recently diagnosed patients with available diagnostic MRI evaluations were included in the study. Main outcome measure: Clinical, biochemical characteristics and MRI signal findings. Results: T2-hypointense adenomas represented 52.9% of the series, were smaller than their T2-hyper- and isointense counterparts (p<0.0001), were associated with higher IGF1 levels (p=0.0001), invaded the cavernous sinus less frequently (p=0.0002) and rarely caused optic chiasm compression (p<0.0001). Acromegalic men tended to be younger at diagnosis than women (p=0.067) and presented higher IGF1 values (p=0.01). Although in total, adenomas had a predominantly inferior extension in 45.8% of cases, in men this was more frequent (p<0.0001), whereas in women optic chiasm compression of macroadenomas occurred more often (p=0.0067). Most adenomas (45.1%) measured between 11-20mm in maximal diameter and bigger adenomas were diagnosed at younger ages (p=0.0001). Conclusions: T2-weighted signal differentiates GH-secreting adenomas into subgroups with particular behaviors. This raises the question of whether T2-weighted signal could represent a factor in the classification of acromegalic patients in future studies. [less ▲]

Context: McCune Albright syndrome (MAS) is a clinical association of endocrine and non-endocrine anomalies caused by post-zygotic mutation of the GNAS1 gene, leading to somatic activation of the stimulatory alpha subunit of G protein (Gsalpha). Important advances have been made recently in describing pathological characteristics of many MAS-affected tissues, particularly pituitary, testicular and adrenal disease. Other rarer disease related features are emerging. Objective: To study pathological and genetic findings of MAS on a tissue-by-tissue basis in classically and non classically affected tissues. Design: A comprehensive autopsy and genetic analysis Setting: Tertiary referral University Hospital Patients: Adult male patient with MAS and severe disease burden including gigantism Intervention(s): Clinical, hormonal and radiographic studies; gross and microscopic pathology analyses, conventional PCR and droplet digital PCR analyses of affected and non affected tissues Main Outcome Measure: Pathological findings, presence of GNAS1 mutations Results: The patient was diagnosed with MAS syndrome at six years of age based on the association of cafe-au-lait spots and radiological signs of polyostotic fibrous dysplasia. Gigantism developed and hyperprolactinemia, hypogonadotropic hypogonadism and hyperparathyroidism were diagnosed throughout adult period. The patient died at the age of 39 from pulmonary embolism. A detailed study revealed mosaiscism for the p.R201C GNAS mutation distributed across many endocrine and non-endocrine tissues. These genetically implicated tissues included rare or previously undescribed disease associations including primary hyperparathyroidism, and hyperplasia of the thymus and endocrine pancreas. Conclusions: This comprehensive pathological study of a single patient highlights the complex clinical profile of MAS and illustrates important advances in understanding the characteristics of somatic GNAS1 related pathology across a wide range of affected organs.

Background: Parathyroid carcinoma (PCa) is rare and often difficult to differentiate initially from benign disease. Because PCa oversecretes amino PTH that is detected by third-generation but not by second-generation PTH assays, the normal generation PTH ( 1) is inverted in PCa (ie, 1). Objective: The objective of the investigation was to study the utility and advantages of automated generation PTH ratio measurements using the Liaison XL platform over existing manual techniques. Setting: The study was conducted at a tertiary-referral academic center. Design: This was a retrospective laboratory study. Subjects: Eleven patients with advanced PCa (mean age 56.0 y). The controls were patients with 1°-hyperparathyroidism (n 144;meanage 53.8 y), renal transplantation (n 41;meanage 50.6 y), hemodialysis (n 80; mean age 65.2 y), and healthy elderly subjects (n 40; mean age 72.6 y). Results: The median (interquartile range) generation PTH ratio was 1.16 (1.10 –1.38) in the PCa group, which was significantly higher than the control groups: 0.74 (hemodialysis, 0.71–0.75), 0.77 (renal transplant, 0.73–0.79), 0.80 (healthy elderly, 0.74–0.83), and 0.76 (1°-hyperparathyroidism, 0.74–0.78). An inverted -generation PTH ratio ( 1) was seen in 9 of 11 PCa patients (81.8%) and in 7 of 305 controls (2.3%), 3 of 80 hemodialysis (3.8%), and 4 of 144 1°-hyperparathyroidism patients (2.8%). Of four PCa patients who had a normal PTH ratio with the manual method, two had an inverted -generation PTH ratio with the automated method. Conclusions: Study of the -generation PTH ratio in large patient populations should be feasible using a mainstream automated platform like the Liaison XL. The current study confirms the utility of the inverted -generation PTH ratio as a marker of PCa (sensitivity: 81.8%; specificity: 97.3%). [less ▲]
