Germline mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene were recently observed in patients with pituitary adenoma predisposition (PAP). Though AIP mutation-positive individuals with prolactin-, mixed growth hormone/prolactin-, and ACTH-producing pituitary adenomas as well as non-secreting pituitary adenomas have been reported, most mutation-positive patients have had ...

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of familial Cushing's syndrome. It is characterized by bilateral adrenocortical hyperplasia with small to normal-sized adrenal glands containing multiple small adrenal cortical pigmented nodules [1,2]. PPNAD may occur in an isolated form or as familial PPNAD. Familial cases of PPNAD are usually associated with Carney compl...

A 60 year-old male was referred for treatment of a cardiac myxoma in the right atrium. He had a past history of left atrial cardiac myxoma at age 49 and pituitary microadenoma related to acromegaly at age 55. He did not have a family history of cardiac neoplasm or endocrinopathy. The intracardiac tumor was resected and its pathology was compatible with myxoma. A diagnosis of Carney complex (CNC...

We present a 25 year old Caucasian male patient with multiple recurrences of cardiac myxomas after surgical removal of the original tumor. His mother was operated on for right ventricular myxoma. The genetic analyses disclosed an aneuploid DNA content by flow cytometry analysis. The familial form of the cardiac myxomas must be distinguished from Carney complex syndrome. A long- term echocardiog...

BACKGROUND Conjunctival myxomas are rare, benign, connective tissue tumours that classically present as slow-growing, painless, well-circumscribed masses (Arch Ophthalmol 124:735-8, 2006; Case Rep Ophthalmol 3:145-50, 2012). There have been 29 cases reported in the literature (Arch Ophthalmol 124:735-8, 2006; Malays J Med Sci 20(1):92-4, 2013; Case Rep Ophthalmol 3:145-50, 2012; Middle East Afr...

Pituitary adenomas are a common feature of a subset of endocrine neoplasia syndromes, which have otherwise highly variable disease manifestations. We provide here a review of the clinical features and human molecular genetics of multiple endocrine neoplasia (MEN) type 1 and 4 (MEN1 and MEN4, respectively) and Carney complex (CNC). MEN1, MEN4, and CNC are hereditary autosomal dominant syndromes ...

The recently recognized higher prevalence of pituitary tumours presents a challenge for endocrinologists and health-care resource providers in terms of diagnostics and therapy. The majority of pituitary tumors arise sporadically as anterior pituitary adenomas but approximately 5% can be attributed to a familial syndrome. The clinical and genetic characteristics of familial pituitary adenomas ha...
