Carney triad is a very rare syndrome characterized by the synchronous or metachronous occurrence of gastrointestinal stromal tumors, pulmonary chondroma, and extra-adrenal paraganglioma. We present the case of a 36-year-old woman with complete Carney triad who underwent a Ga-DOTA-TATE PET/CT scan for restaging of metastasizing extra-adrenal paraganglioma and for evaluation of targeted radionuclide therapy potential. On the Ga-DOTA-TATE PET scan, increased tracer accumulation was observed in paraganglioma metastases...

BackgroundThe majority of pituitary adenomas are sporadic, but about 5% of them occur in a familial setting, predominantly in multiple endocrine neoplasia type 1 and Carney complex. Familial isolated pituitary adenomas (FIPA), unrelated to the syndromes mentioned above, were also described. The clinical course of FIPA differs significantly from sporadic cases, and is characterized by a larger tumor size, more aggressive course and younger patients' age at the moment of recognition. ObjectivesThe aim of this retrospective study is to present 4 families in which two closely related people were diagnosed with pituitary adenomas...

Context: Carney complex (CNC) is a rare multiple neoplasia syndrome involving cardiac, endocrine, neural, and cutaneous tumors and a variety of pigmented skin lesions. CNC can be inherited as an autosomal dominant trait, but in about one-third of patients, the disease is caused by de novo mutation in the PRKAR1A gene localized on chromosome 17q22-24. Most of the mutations include single base substitutions and small deletions/insertions not exceeding 15 base pairs. Recently, large germline PRKAR1A deletions have been described and may cause a more severe phenotype...

Sweet syndrome, or acute febrile neutrophilic dermatosis, is a systemic disease process mainly characterized by hyperpyrexia and skin lesions. A newly described entity, necrotizing Sweet syndrome, is a severe and locally aggressive dermatological condition that clinically and histopathologically resembles a necrotizing soft tissue infection. It is characterized by pathergy, a nonspecific inflammatory response to cutaneous trauma resulting in a propagation of the disease. In contrast to a necrotizing infection, this condition responds to systemic steroids...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of Cushing syndrome, especially the isolated form without Carney complex, associated with germline mutations in PRKAR1A, the protein kinase A regulatory subunit type 1 alpha gene. We report a 31-year-old female who presented with secondary amenorrhea, cushingoid appearance, and hypertension without Carney complex. Biochemical laboratory examinations confirmed the ACTH-independent adrenal Cushing syndrome with negative Liddle test. A small right adrenal adenoma of 0...

Carney Complex (CNC) is a multiple neoplasia syndrome characterized by skin tumors and pigmented lesions, myxomas, and various endocrine tumors. The aim of this case report was to describe a case of CNC with a novel PRKAR1A mutation. A man aged 46 years with a medical history of surgery for cardiac myxomas at the age of 39 was admitted to our hospital because of four newly-developed heart masses. The histologic examination confirmed cardiac myxomas. He had many presentations of CNC such as growth hormone (GH) and prolactin (PRL)-secreting mixed pituitary adenoma, benign thyroid nodule, large-cell calcifying Sertoli cell tumor (LCCST), and superficial angiomyxoma...

In this report, we review the relationship between succinate dehydrogenase (SDH) deficiency and the epigenome, especially with regards to two clinical conditions. Carney triad (CT) is a very rare disease with synchronous or metachronous occurrence of at least three different tumor entities; gastric gastrointestinal stromal tumor (GIST), paraganglioma (PGL), and pulmonary chondroma. This condition affects mostly females and it is never inherited. Another disease that shares two of the tumor components of CT, namely GIST and PGL is the Carney-Stratakis syndrome (CSS) or dyad...

OBJECTIVE: As the number of commercially available wound dressings is increasing rapidly, it is important for clinicians to understand the strengths and limitations of each and to recognise relationships between wound type and dressing properties to obtain optimal healing results. Our aim is to test the antimicrobial activity of two dressings. METHOD: A hydroconductive (HC) dressing and a silver-impregnated foam (SIF) dressing were compared for their potential to reduce the levels meticillin-resistant Staphylococcus aureus (MRSA)...

The identification of at-risk kindreds facilitates screening and risk reduction strategies for patients with hereditary cancer predisposition syndromes. Recently, immunohistochemistry (IHC) has emerged as a cost-effective strategy for detecting or inferring the presence of mutations in both tumors and the germline of patients presenting with tumors associated with hereditary cancer predisposition syndromes. In this review we discuss the use of novel IHC markers, including PRKAR1A, β-catenin, SDHB, fumarate hydratase and 2SC, HRASQ61R, BAP1, parafibromin and glucagon, which have either established applications or show promise for surgical pathologists to complement morphological or clinical suspicion of hereditary cancer predisposition syndromes...

The failure of the polycystins (PCs) to function in primary cilia is thought to be responsible for autosomal dominant polycystic kidney disease (ADPKD). Primary cilia integrate multiple cellular signaling pathways, including calcium, cAMP, Wnt, and Hedgehog, which control cell proliferation and differentiation. It has been proposed that mutated PCs result in reduced intracellular calcium, which in turn upregulates cAMP, protein kinase A (PKA) signaling, and subsequently other proliferative signaling pathways...

Anthony J Tracey, Wolfgang H Cerwinka
Large-cell calcifying Sertoli cell tumor (LCCSCT) of the testis is an exceptionally rare lesion, found sparsely in any medical literature. There is a correlation between this entity and Peutz-Jeghers syndrome and Carney complex (40% of tumors). The remaining 60% of tumors are sporadic. A 13-year-old male patient underwent a left partial orchiectomy. Intraoperative frozen section was used, and pathology revealed a benign LCCSCT with negative margins. To our knowledge, there is not a case in the literature of an LCCSCT being treated with partial orchiectomy in a pubertal male with a normal contralateral testis...

BACKGROUND: Internalizing disorders (IDs), consisting of the syndromes of anxiety and depression, are common, debilitating conditions often having onsets in adolescence. Scientists have developed dimensional self-report instruments that assess putative negative valence system (NVS) trait-like constructs as complimentary phenotypes to clinical symptoms. These include various measures that index temperamental predispositions to IDs and correlate with neural substrates of fear, anxiety, and affective regulation...

CONTEXT: Carney complex (CNC) is an autosomal dominant condition caused, in most cases, by an inactivating mutation of the PRKAR1A gene, which encodes for the type 1 alpha regulatory subunit of protein kinase A. CNC is characterized by the occurrence of endocrine overactivity, myxomas and typical skin manifestations. Cushing syndrome due to primary pigmented nodular adrenocortical disease (PPNAD) is the most frequent endocrine disease observed in CNC. CASE DESCRIPTION: Here, we describe the first case of a patient with CNC and adrenocorticotropic hormone (ACTH)-dependent Cushing disease due to a pituitary corticotroph adenoma...

A 14-year-old male was referred for dyslipidemia. His findings were consistent with metabolic syndrome. Although he lacked the typical physical appearance, his accelerated weight gain combined with a decreased linear growth velocity suggested Cushing syndrome. He was subsequently found to have adrenocorticotropic hormone-independent Cushing syndrome secondary to primary pigmented nodular adrenal disease without Carney Complex. After bilateral adrenalectomy, his lipid profile returned to normal. In this article, we discuss the role of glucocorticoids on lipid and lipoprotein metabolism...

REVIEW
Pedro Marques, Márta Korbonits
Although most of pituitary adenomas are benign, they may cause significant burden to patients. Sporadic adenomas represent the vast majority of the cases, where recognized somatic mutations (eg, GNAS or USP8), as well as altered gene-expression profile often affecting cell cycle proteins have been identified. More rarely, germline mutations predisposing to pituitary adenomas -as part of a syndrome (eg, MEN1 or Carney complex), or isolated to the pituitary (AIP or GPR101) can be identified. These alterations influence the biological behavior, clinical presentations and therapeutic responses, and their full understanding helps to provide appropriate care for these patients...

The syndrome of Familial Non Medullary Thyroid Carcinoma (FNMTC) includes two or more patients with an isolated non-medullary thyroid cancer (papillary, follicular, anaplastic) within the same family. To diagnose FNMTC, the clinician must exclude a syndromic presentation such as the syndromes of Cowden, Gardner or Werner, and the Carney Complex. Up to now, a hundred families with FNMTC have been genetically studied, including forms with (Ch19p13.2) or without oxyphilia (Ch2q21), in association with a multinodular goiter (Ch14q32), or with a renal cancer (Ch1q21)...

Cardiac myxoma is the most common cardiac tumour. Most lesions occur sporadically, but occasional lesions develop in patients with Carney complex, a syndrome characterized by cardiac myxoma, spotty pigmentation, and endocrine overactivity. Two-thirds of patients with Carney complex harbour germline mutations in PRKAR1A, which encodes the type I regulatory subunit of protein kinase A (PKA). Most studies have not found a mutation in PRKAR1A in sporadic cardiac myxoma cases. Recent studies identified frequent mutations in PRKACA, which encodes the catalytic subunit of PKA, in cortisol-secreting adrenocortical adenoma cases...
