Carney complex cardiac myxoma

A cardiac myxoma is a rare tumor that could be incidental or present with common symptoms due to embolization. A minority of cases are attributed to carney complex, a rare inherited disease. A 73-year-old Asian male presented with acute left-side weakness, slurred speech, gait imbalance, and subacute constitutional symptoms. Left atrial myxoma was discovered by computed tomography and confirmed by echocardiography. Brain imaging revealed pituitary macroadenoma with subarachnoid and intraventricular hemorrages...

Background: Mutations in PRKAR1A gene can lead to Carney complex (CNC), and most CNC patients develop cardiac and cutaneous myxomas. In particular, cardiac myxomas are a common cause of mortality in CNC patients. Cutaneous myxomas of the external ear are extremely rare, and do not have any specific clinical features Methods: In this retrospective study, we analyzed the clinical and genetic data of the proband and his family and fifty whole blood control samples selected from the molecular genetic database of our hospital...

INTRODUCTION AND IMPORTANCE: Ocular myxomas are very rare and can involve the orbit, eyelids, and conjunctiva. Conjunctival myxoma can be misdiagnosed as amelanotic nevus, conjunctival cyst, or ocular surface squamous neoplasia, among others. They can appear as an isolated lesion or can be associated with systemic manifestations as part of the Carney complex or Zollinger-Ellison syndrome. CASE PRESENTATION: We describe a 64-year-old healthy male who presented with a right eye painless peri-limbal salmon-colored patch lesion in the infero-temporal bulbar conjunctiva over a period of 2 years...

Carney complex (CNC) is a rare multiple tumour syndrome characterized by cutaneous pigmented lesions, myxoma and endocrine tumours, among others, and is inherited as an autosomal dominant trait. Protein kinase cAMP-dependent type I regulatory subunit alpha ( PRKAR1A ) is known to be the responsible gene. Breast myxomatosis and ductal adenoma, which are regarded as benign, are well-known mammary lesions of CNC and are included in the main diagnostic criteria. In this case, a 59-year-old woman with repeated cardiac myxoma was diagnosed with CNC with PRKAR1A mutation...

Cardiac myxomas are common primary neoplasms of the heart. They are biologically benign but "functionally malignant" because of the potential for embolization. They arise most commonly from the left atrium, but no chambers of the heart are immune. They may be sporadic in the majority but also familial as a part of the Carney complex. Two morphological forms exist: polypoid and papillary. Polypoid myxomas often present with obstructive features, while the papillary forms are more prone to embolization. Histogenesis is still controversial; the current view centres around origin from the primitive pluripotent mesenchymal cells...

Carney complex (CNC) is a rare hereditary syndrome that involves endocrine dysfunction and the development of various types of tumors. Chromosome 2p16 and PRKAR1A on chromosome 17 are known susceptibility loci for CNC. Here we report a mother and son with CNC caused by an 8.57-kb deletion involving the transcription start site and non-coding exon 1 of PRKAR1A. The proband is a 28-year-old male with bilateral large-cell calcified Sertoli cell testicular tumors and pituitary adenoma. Comprehensive genomic profiling for cancer mutations using Foundation One CDx failed to detect any mutations in PRKAR1A in DNA from the testicular tumor...

We herein report a case of Carney complex (CNC) complicated with primary pigmented nodular adrenocortical disease (PPNAD) after unilateral adrenalectomy. A 44-year-old woman was admitted to our hospital for PPNAD surgery. She had previously undergone surgery for cardiac myxoma and had a PRKAR1A mutation with no family history of CNC. She had Cushing's signs, but her metabolic abnormalities were mild. Adrenal insufficiency due to poor medication adherence was a concern, so she underwent unilateral adrenalectomy...

BACKGROUND Intracardiac tumors are a rare entity, with myxomas being the most common among them (approximately 50% of intracardiac tumors). Up to 80% of myxomas originate within the left atrium and while most are incidental or isolated findings in asymptomatic patients, others may result in clinical manifestations of heart failure or emboli. Moreover, in some cases, myxomas can be part of a genetically inherited syndrome known as Carney complex (CNC), and present with varied phenotypes, including skin, endocrine, and neuroendocrine tumors...

Carney complex is a rare syndrome caused by a genetic mutation leading to multiple endocrine abnormalities and a variety of tumors. Here, we report a case of Carney complex diagnosed due to recurrent multiple myxomas in the right atrium of a patient 16 years after the resection of the primary left atrial myxoma. Surgical excision was performed for the multiple recurrent right atrial tumors under cardiopulmonary bypass. The patient remained complication-free after surgery and was discharged on the 14th day...

Superficial angiomyxomas are cutaneous mesenchymal tumours that typically present clinically as slow-growing, solitary, asymptomatic nodules that can occur at any age. Histopathologically, these dermal and subcutaneous tumours are characterized by abundant myxoid stroma, numerous thin-walled and often arbourising blood vessels, and spindled to stellate fibroblast-like cells. While usually sporadic, superficial angiomyxomas can occasionally be associated with Carney complex (CNC), an autosomal dominant disorder characterized by inactivating germline mutations in the 1-alpha regulatory subunit of protein kinase A (PRKAR1A) and various clinical manifestations, including cardiac myxomas, facial lentigines, epithelioid blue naevi, endocrinopathies and psammomatous melanotic schwannomas...

Carney complex is a rare genodermatosis characterized by cardiac and cutaneous myxomas, among other tumors. In the majority of cases, cutaneous myxomas precede the diagnosis of cardiac myxomas, which are the main cause of death in these patients. Despite the fact that the diagnosis of cutaneous myxomas is histopathological, high-frequency ultrasonography plays an essential role in the differential diagnosis with other cutaneous and subcutaneous tumors. The authors of the present study describe, for the first time in the literature, the ultrasonographic features of both variants of cutaneous myxomas, superficial and subcutaneous, in a patient with a Carney complex...

The Carney complex (CNC) is a rare autosomal dominant genetic complex that is characterised by multiple neoplasms consisting of neuroendocrine and cardiac tumours, with only 750 cases reported worldwide as of 2017. Cardiac tumours, in the context of the CNC, are of unique importance since the leading causes of death in patients with CNC are cardiac. To prevent sudden cardiac death and embolic events, a difficult diagnosis must be made and postdiagnostic screenings must be regular. We present a case of a 52-year-old man, with a medical history of pituitary microadenoma and facial lentiginosis, who presented with dyspnoea 2 months after suffering a cerebrovascular accident...

BACKGROUND: Carney complex (CNC) is an uncommon multisystem endocrine disorder with significant variability of clinical manifestations including mucocutaneous involvement (pigmented lesions, myxomas, blue nevi, etc.), endocrine tumors (adrenal, pituitary, thyroid glands, or testicles), and non-endocrine tumors [cardiac myxomas, psammomatous melanotic schwannomas (PMS), breast myxomas as well as ductal adenomas, and osteochondromyxomas]. To our knowledge, this is the second report of CNC in Iran, presenting with typical manifestations...

Described for the first time in 1985, Carney complex (CNC) is a rare dominantly inherited multiple neoplasia syndrome with almost full penetrance and characterized by both endocrine - primary pigmented nodular adrenocortical disease with Cushing's syndrome, acromegaly and thyroid tumors - and non-endocrine manifestations such as cardiac, cutaneous and mucosal myxomas, pigmented cutaneous lesions, psammomatous melanotic schwannoma, osteochondromyxoma and a wide range of other tumours with potential malignancy...

A 59-year-old man with a palpable mass above the left eyebrow that had appeared over a 1-year period presented to our clinic. He previously had been administered antiglaucoma eyedrops for pseudophakic glaucoma of the left eye and had undergone Ahmed glaucoma valve implant surgery. The palpable mass above the left eyebrow was soft, nontender, and large. On slit lamp examination, the Ahmed valve was positioned in the superotemporal quadrant of the limbal conjunctiva, and there was no other abnormal finding. Computerized tomography (CT) imaging showed a dense, soft tissue lesion in the left upper lateral periorbital area...

Carney complex (CNC) is a rare, autosomal dominant multiple neoplasia syndrome. Although cutaneous myxomas commonly occur in CNC patients, intraoral myxomas are extremely rare. We present a case of a palatal myxoma in a 21-year-old female patient with CNC, along with a review of the pertinent literature. She presented with a sessile nodule on the hard palate that microscopically showed a multilobulated and highly vascularized myxomatous tissue composed of loosely-arranged spindle, polygonal, and stellate cells, suggestive of myxoid neurofibroma...

Cardiac myxoma is a benign neoplasm composed of stellate to plump, cytologically bland mesenchymal cells set in a myxoid stroma. Although benign, as they can lead to severe complications, they are often removed surgically. A 39-year-old female presented with a chief complaint of generalized fatigue. Patient had a history of a large 7cm x 2.5cm left atrial myxoma resected at the age of 32 years after she presented with symptoms of dyspnea on exertion. The dyspnea was due to prolapse of the mass through the mitral valve during diastole, leading to functional severe mitral stenosis...

PURPOSE: Carney complex (CNC), is an autosomal dominant multiple neoplasia and lentiginosis syndrome. We aimed to identify risk factors associated with the occurrence and recurrence of cardiac myxomas, the predominant cause of death in CNC patients. METHODS: Patients with CNC were monitored prospectively between 1995 and 2020 for the development of cardiac myxomas. RESULTS: Of the 319 patients studied, 136 (42.6%) developed myxomas. The mean age at diagnosis was 28...
