Introduction : This review explores insights provided by next-generation sequencing (NGS) of pituitary tumors and the clinical implications. Areas covered : Although syndromic forms account for just 5% of pituitary tumours, past Sanger sequencing studies pragmatically focused on them. These studies identified mutations in MEN1, CDKN1B, PRKAR1A, GNAS and SDHx causing Multiple Endocrine Neoplasia-1 (MEN1), MEN4, Carney Complex-1, McCune Albright Syndrome and 3P association syndromes, respectively. Furthermore, linkage analysis of single-nucleotide polymorphisms identified AIP mutations in 20% with familial isolated pituitary adenomas (FIPA)...

Intramuscular myxomas (IMMs) are rare benign tumors of mesenchymal origin that are most often located in large skeletal muscles, particularly of the thigh. They have also been reported within the paraspinal musculature and should be considered in the differential diagnosis of a paraspinal mass. These lesions can cause neurological symptoms due to mass effect. This is a report of a 52-year-old man with multiple paraspinal tumors that exhibited concerning growth on serial imaging studies. To the authors' knowledge, this represents the first report of a patient with multiple paraspinal myxomas...

Gastrointestinal stromal tumors (GISTs) are increasingly recognized as having diverse biology. With the development of tyrosine kinase inhibitors molecularly matched to oncogenic KIT and PDGFRA mutations, GISTs have become a quintessential model for precision oncology. However, about 5-10% of GIST lack these driver mutations and are deficient in succinate dehydrogenase (SDH), an enzyme that converts succinate to fumarate. SDH deficiency leads to accumulation of succinate, an oncometabolite that promotes tumorigenesis...

Adrenocortical malignancies can occur in the context of several tumor predisposition syndromes.The Carney complex (CNC) is responsible for the majority of primary pigmented nodular adrenal diseases and is more rarely associated with adrenocortical carcinoma (ACC). Other core manifestations of CNC include cardiac and cutaneous myxomas, lentiginosis, somatotroph pituitary adenomas, Sertoli tumors, melanocytic schwannoma, and thyroid, breast, and bone tumors. CNC is mostly due to germline inactivating mutations of PRKAR1A...

Angelman syndrome (AS) is a neurodevelopmental disorder characterized by intellectual disability, lack of speech, ataxia, EEG abnormalities, and epilepsy. Seizures in AS individuals are common, debilitating, and often drug-resistant. Therefore, there is an unmet need for better treatment options. Cannabidiol (CBD), a major phytocannabinoid constituent of cannabis, has antiseizure activity and behavioral benefits in preclinical and clinical studies for some disorders associated with epilepsy, suggesting that the same could be true for AS...

BACKGROUND: Cardiac myxoma, a common benign primary tumor of the heart can be categorized into syndromic (Carney Complex) and non-syndromic(isolated). Carney Complex associated myxomas can be found in any region and system (cardiac, cutaneous, osseous, genitalia), and may manifest at a tender age. On the contrary, non-syndromic cardiac myxomas are usually confined to the chambers, and symptoms often present from 5th decade of life. Aortic valve myxoma is a very unusual occurrence, and presentation in a teen is extremely rare...

Melanotic schwannoma (MS) is a rare nerve sheath tumor with fewer than 200 cases reported. MS has uncertain malignant potential and comprises 1% of all nerve sheath tumors with a predilection for the spinal nerve roots. An even rarer location for this tumor is the vagina. Up to 55% of MSs that contain psammoma bodies are associated with the Carney complex, an autosomal dominant syndrome. Criteria for malignancy in MS are still not well established and long term follow-up of patients is recommended. A 26-year-old woman presented with a bleeding vaginal tumor which was diagnosed as MS following excision...

Large cell calcifying Sertoli cell tumors (LCCSCTs) are rare testicular tumors, representing <1% of all testicular neoplasms. Almost 40% of patients with LCCSCTs will present in the context of an inherited tumor predisposition condition, such as Carney complex (CNC) or Peutz-Jeghers syndrome. We report the case of a 42-year-old man who had presented with a right testicular mass, and was diagnosed with metastatic LCCSCT. The patient underwent radical orchiectomy, achieving initial remission of his disease...

The epithelioid blue nevus (EBN) is a variant of the blue nevus characterized by heavily pigmented epithelioid melanocytes and lightly or nonpigmented spindle cells. It may be associated with Carney complex, a multiple neoplasia syndrome. Congenital cases of EBN not associated with Carney complex are rarely reported. We herein describe an infant who presented with multiple blue-gray nodules and papules involving the head, trunk, and extremities at birth, the corresponding histopathologic findings, and genetic testing results...

PURPOSE: Carney complex (CNC) is a rare autosomal dominant syndrome, characterized by mucocutaneous pigmentation, cardiac, cutaneous myxomas and endocrine overactivity. It is generally caused by inactivating mutations in the PRKAR1A (protein kinase cAMP-dependent type I regulatory subunit alpha) gene. Acromegaly is an infrequent manifestation of CNC, reportedly diagnosed in 10% of patients. METHODS: We here report the case of a patient who was concomitantly diagnosed with Carney complex, due to a new mutation in PRKAR1A ((NM_002734...

The thyroid is the most common site of endocrine cancer. One type of thyroid cancer, non-medullary thyroid cancer (NMTC), develops from follicular cells and represents approximately 90% of all thyroid cancers. Approximately 5%-15% of NMTC cases are thought to be of familial origin (FNMTC), which is defined as the occurrence of the disease in three or more first-degree relatives of the patient. It is often divided into two groups: Syndrome-associated and non-syndromic. The associated syndromes include Cowden syndrome, familial adenomatous polyposis, Gardner syndrome, Carney complex and Werner syndrome...

AIMS: Pulmonary chondromas, which are rare cartilaginous neoplasms that often arise in the setting of Carney triad, are morphologically similar to pulmonary hamartomas, which are much more common. There is evidence that succinate dehydrogenase (SDH) deficiency drives neoplasia in patients with Carney triad, and SDHB immunohistochemistry can be used as a surrogate marker to detect SDH deficiency. The aim of this study was to investigate the utility of SDHB immunohistochemistry in distinguishing pulmonary chondromas from hamartomas...

Carney-Stratakis Syndrome (CSS) comprises of paragangliomas (PGLs) and gastrointestinal stromal tumors (GISTs). Several of its features overlap with Carney Triad (CT) - PGLs, GISTs, and pulmonary chondromas. CSS has autosomal dominant inheritance, incomplete penetrance, and greater relative frequency of PGL over GISTs. The PGLs in CSS are multicentric and GISTs are multifocal in all the patients, suggesting an inherited susceptibility and associating the two manifestations. In this review, we highlight the clinical, pathological, and molecular characteristics of CSS, along with its diagnostic and therapeutic implications...

Succinate dehydrogenase (SDH)-deficient gastrointestinal stromal tumor (GIST) is a subset of wild-type GIST that constitutes approximately 10% of gastric GISTs. SDH-mutated GISTs lack mutations in the proto-oncogene receptor tyrosine kinase (also known as KIT, c-KIT, or CD117) or platelet-derived growth factor receptor α (PDGFR-α). These tumors have female predilection, affect children and young adults, and have a spectrum of behavior from indolent to progressive. These tumors have characteristic morphologic features including multinodular architecture, multiple tumors, lymphovascular involvement, and occasional lymph node metastasis...

Carney complex (CNC) is multiple neoplasia syndrome characterized by pigmented lesions of the skin and mucosa, cardiac, cutaneous and other myxomas, and multiple endocrine and non– endocrine tumors. Most of the cases have an inactivating mutation in PRKAR1A gene. Osteochondromyxoma (OMX) is an extremely rare myxomatous tumor of bone, affecting 1% of CNC patients. Large cell calcifying Sertoli cell tumor (LCCSCT) is a testicular tumor affecting more than 75 % of males with CNC. Here, we report a atypical case of CNC without typical pigmented skin lesions, presenting with a bone based tumor as the first manifestation...

BACKGROUND: The overall survival of patients with localised osteosarcoma has dramatically improved with the introduction of multidrug chemotherapeutic regimens into the treatment paradigm. However, despite optimal treatment, all-cause mortality remains higher among osteosarcoma survivors than in the general population. The development of second malignant neoplasms contributes to this higher mortality rate. CASE SERIES: We present three cases of patients definitively treated for osteosarcoma who subsequently developed a second malignant neoplasm...

Carney complex (CNC) is a rare multiple neoplasia syndrome characterized by spotty pigmentation of the skin and mucosa in association with various non-endocrine and endocrine tumors, including primary pigmented nodular adrenocortical disease (PPNAD). A 20-year-old woman was referred for suspected Cushing syndrome. She had signs of cortisol excess as well as skin lentigines on physical examination. Biochemical investigation was suggestive of corticotropin (ACTH)-independent Cushing syndrome. Unenhanced computed tomography scan of the abdomen did not reveal an obvious adrenal mass...
