Pathological processes of the ADRENAL CORTEX.
A benign neoplasm derived from connective tissue, consisting chiefly of polyhedral and stellate cells that are loosely embedded in a soft mucoid matrix, thereby resembling primitive mesenchymal tissue. It occurs frequently intramuscularly where it may be mistaken for a sarcoma. It appears also in the jaws and the skin. (From Stedman, 25th ed)
Small circumscribed melanoses resembling, but differing histologically from, freckles. The concept includes senile lentigo ('liver spots') and nevoid lentigo (nevus spilus, lentigo simplex) and may also occur in association with multiple congenital defects or congenital syndromes (e.g., Peutz-Jeghers syndrome).
A type I cAMP-dependent protein kinase regulatory subunit that plays a role in confering CYCLIC AMP activation of protein kinase activity. It has a lower affinity for cAMP than the CYCLIC-AMP-DEPENDENT PROTEIN KINASE RIBETA SUBUNIT.
Autosomal dominant syndrome characterized by cardiac and cutaneous MYXOMAS; LENTIGINOSIS (spotty pigmentation of the skin), and endocrinopathy and its associated endocrine tumors. The cardiac myxomas may lead to SUDDEN CARDIAC DEATH and other complications in Carney complex patients. The gene coding for the PRKAR1A protein is one of the causative genetic loci (type 1). A second locus is at chromosome 2p16 (type 2).
A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.
Tumors or cancers of the ADRENAL CORTEX.
A benign neoplasm of the ADRENAL CORTEX. It is characterized by a well-defined nodular lesion, usually less than 2.5 cm. Most adrenocortical adenomas are nonfunctional. The functional ones are yellow and contain LIPIDS. Depending on the cell type or cortical zone involved, they may produce ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE.
A group of autosomal dominant diseases characterized by the combined occurrence of tumors involving two or more ENDOCRINE GLANDS that secrete PEPTIDE HORMONES or AMINES. These neoplasias are often benign but can be malignant. They are classified by the endocrine glands involved and the degree of aggressiveness. The two major forms are MEN1 and MEN2 with gene mutations on CHROMOSOME 11 and CHROMOSOME 10, respectively.

Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
A small, unpaired gland situated in the SELLA TURCICA. It is connected to the HYPOTHALAMUS by a short stalk which is called the INFUNDIBULUM.
Disorders involving either the ADENOHYPOPHYSIS or the NEUROHYPOPHYSIS. These diseases usually manifest as hypersecretion or hyposecretion of PITUITARY HORMONES. Neoplastic pituitary masses can also cause compression of the OPTIC CHIASM and other adjacent structures.
The anterior glandular lobe of the pituitary gland, also known as the adenohypophysis. It secretes the ADENOHYPOPHYSEAL HORMONES that regulate vital functions such as GROWTH; METABOLISM; and REPRODUCTION.

Novel PRKAR1A gene mutations in Carney Complex. (6/26)

Carney complex is a syndrome that may include cardiac and mucocutaneous myxomas, spotting skin pigmentation, and endocrine lesions. Many patients with Carney complex have been shown to have a stop codon mutation in the PRKAR1A gene in the 17q22-24 region. Here we present the case of a 57 year-old man with multiple skin lesions and cardiac myxomas. Histology of the skin lesions showed lentigenous melanocytic hyperplasia and cutaneous myxomas, confirming the diagnosis of Carney complex. Lesional and control normal tissue from the patient were identified and sequenced for the PRKAR1A gene. A germline missense mutation was identified at exon 1A. This is the first report of this mutation, and one of the few reported missense mutation associated with Carney complex. This finding strengthens the argument that there are alternative ways in which the protein kinase A 1-alpha subunit plays a role in tumorigenesis.  (+info)

Primary pigmented nodular adrenocortical disease is a rare cause of adrenocorticotropic hormone-independent Cushings syndrome. We report an uncommon primary pigmented nodular adrenocortical disease case presenting with a unilateral adrenocortical nodule and provide a brief overview of the existing literature. A 27-year-old Caucasian woman was admitted to our Department with adrenocorticotropic hormone-independent Cushings syndrome. Its cause was initially considered a left adrenocortical adenoma based on computer tomography imaging. The patient underwent left laparoscopic adrenalectomy and histological examination revealed pigmented micronodular adrenal hyperplasia. Evaluation for the presence of Carney complex was negative. Six months later recurrence of hypercortisolism was documented and a right laparoscopic adrenalectomy was performed further establishing the diagnosis of primary pigmented nodular adrenocortical disease. After a nine-year follow-up there is no evidence of residual disease. Even
Primary pigmented nodular adrenocortical disease (PPNAD) is a pituitary-independent, primary adrenal form of hypercortisolism characterized by (a) resistance to suppression by dexamethasone and abolition of the normal diurnal rhythm of cortisol secretion, and (b) distinctive, bilateral, histopathologic changes of the adrenal glands, such as the formation of variably sized, pigmented nodular adenomas, loss of normal zonation and atrophy of the extranodular cortex. PPNAD can be associated with a variety of other manifestations, such as myxomas of the skin, heart, breast and other sites, psammomatous melanotic swannomas involving the peripheral nervous system (PNS), lentigines and blue nevi of the skin and mucosae, growth hormone (GH)-producing adenomas of the pituitary, testicular Sertoli cell tumors, and possibly other neoplasms (adrenocortical and thyroid follicular carcinoma, and ovarian cysts). These associations constitute a distinct clinical syndrome, Carney complex, a genetic syndrome. At ...

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. She subsequently underwent bilateral laparoscopic adrenalectomy, and histopathology was consistent with PPNAD. Genetic testing revealed a novel frameshift pathogenic variant c.488delC/p.Thr163MetfsX2 (ClinVar Variation ID: 424516) in the PRKAR1A gene, consistent with clinical suspicion for CNC. Evaluation for other clinical features of the complex was unrevealing. We present a case of PPNAD-associated Cushing syndrome ...

Genetic variants in components of the protein kinase A (PKA) enzyme have been associated with various defects and neoplasms in the context of Carney complex (CNC) and in isolated cases, such as in primary pigmented nodular adrenocortical disease (PPNAD), cortisol-producing adrenal adenomas (CPAs), and various cancers. PRKAR1A mutations have been found in subjects with impaired cAMP-dependent signaling and skeletal defects; bone tumors also develop in both humans and mice with PKA abnormalities. We studied the PRKACB gene in 148 subjects with PPNAD and related disorders, who did not have other PKA-related defects and identified two subjects with possibly pathogenic PRKACB gene variants and unusual bone and endocrine phenotypes. The first presented with bone and other abnormalities and carried a de novo c.858_860GAA (p.K286del) variant. The second subject carried the c.899C,T (p.T300M or p.T347M in another isoform) variant and had a PPNAD-like phenotype. Both variants are highly conserved in the ...

The spotty skin pigmentation and lentigines occur most commonly on the face, especially on the lips, eyelids, conjunctiva and oral mucosa.[3] Cardiac myxomas may lead to embolic strokes and heart failure[4] and may present with fever, joint pain, shortness of breath, diastolic rumble and tumor plop. Myxomas may also occur outside the heart, usually in the skin and breast. Endocrine tumors may manifest as disorders such as Cushing syndrome. The most common endocrine gland manifestation is an ACTH-independent Cushings syndrome due to primary pigmented nodular adrenocortical disease (PPNAD). The LAMB acronym refers to lentigines, atrial myxomas, and blue nevi.[1] NAME refers to nevi, atrial myxoma, myxoid neurofibromas, and ephelides.[1] Testicular cancer, particularly Sertoli cell type, is associated with Carney syndrome.[5] Thyroid and pancreas cancer may also occur.[6][7] Although J Aidan Carney also described Carneys triad it is entirely different.[8] ...
Introduction: We present a rare variety of adrenocorticotrophic hormone (ACTH)-independent Cushings syndrome known as primary pigmented nodular adrenocortical disease (PPNAD). Clinical Picture: The patient initially underwent unilateral adrenalectomy for what was thought to be a left adrenal adenoma. Outcome: Partial resolution of symptoms and demonstrable persistent hypercortisolism after surgery prompted further evaluation with findings leading to the diagnosis of Carney complex. A review of the adrenal histology was consistent with PPNAD. Conclusion: This entity of PPNAD, which has rarely been reported in Asians, forms part of the Carney complex. The diagnosis may not be simple and straightforward, as illustrated in this patient ...

In 1977, Dr. J. Aidan Carney, a pathologist at the Mayo Clinic, first described Carneys Triad. Carneys Triad occurs mostly in younger females. Patients with Carneys triad may have several different types of tumors including GIST, pulmonary chondroma, and paragangliomas. If any two of these tumors are present, a diagnosis of the triad is usually made. In about 2001, Dr. Carney began working with Dr. Constantine Stratakis, a Pediatric Endocrinologist at the National Institute of Health. An important clue was that a few of the Triad cases appeared to be familial (run in families). When Carney and Stratakis focused on the familial cases they noted two important differences compared to the rest of the Triad cases. First, the patients in the familial group never had pulmonary chondromas. The second thing that they found was that the familial group had many more males (almost half were males) than the rest of the patients with Carneys Triad, which had many more females than males. In 2002, ...

Assessment of cytologic evaluation of preputial epithelial cells as a diagnostic test for detection of adrenocortical disease in castrated ferrets
Pituitary tumours occur with increased frequency among patients with CNC.8PRKAR1A, the gene mutated in almost half of the patients with CNC,1,2 codes for the most abundant regulatory subunit of cAMP dependent PKA, a cellular system highly involved in pituitary cell growth and function.13,15,16 In the present study, we investigated the hypothesis that LOH or alterations of PRKAR1As sequence are involved in sporadic pituitary tumours, as well as inherited, non-CNC related pituitary tumours. The results of the experiments described here suggested that the RI-α subunit of PKA is not a significant contributor to tumorigenesis in pituitary cells, as shown by infrequent LOH of the PRKAR1A 17q22-24 locus and lack of PRKAR1A mutations in a large international series of pituitary tumours. Although the number of families that was investigated was small, we may also conclude from this study that PRKAR1A mutations are not responsible for a significant number of non-CNC related inherited pituitary lesions. ...
