Presentation
Clinical description Although the majority of cases are diagnosed in the 2nd and 3rd decades of life, a substantial proportion of patients present during early childhood (2-3 years). [orpha.net]
Endocrine tests showed that the sister of our patient also presented PPNAD requiring bilateral adrenalectomy and a similar histopathological pattern was observed. [ncbi.nlm.nih.gov]
Entire Body System
-
Cushingoid
Cushingoid features still did not appear 122 months after left adrenalectomy. In May 2011, this patient was readmitted due to cushingoid characteristics. Paradoxical rise of 24-h UFC to 2-day HDDST was demonstrated. [ncbi.nlm.nih.gov]
-
Supraclavicular Fat Pads
On examination, she had a significant cushingoid appearance with a round face, thin skin, supraclavicular fat pad, and proximal muscle weakness. There were purplish striae on her lower abdomen and numerous acne lesions on her face. [karger.com]
Cardiovascular
-
Chest Pain
At age 22 years she complained of fatigue and palpitations associated with mid-chest pain. Four cardiac myxomas, suspected from the echocardiogram, were surgically removed. [ncbi.nlm.nih.gov]
Musculoskeletal

Severe Osteoporosis
As the clinical presentation of Cushing syndrome in this group of patients may be atypical (severe osteoporosis or short stature), the detection of multiple, small adrenocortical nodules with CT or MR imaging supports, or may even suggest, the diagnosis [ncbi.nlm.nih.gov]
Patients with PPNAD often present with atypical CS, which is characterized by an asthenic, rather than obese, body habitus caused by severe osteoporosis, short stature and severe muscle and skin wasting. [orpha.net]
The clinical presentation of CS in this group of patients may be atypical, with common manifestations including an asthenic body habitus, short stature, severe osteoporosis, and severe muscle and skin wasting [ 2 ]. [doi.org]
Face, Head & Neck
-
Round Face
Her round face, easily bruised skin, and proximal myopathy all improved significantly. The dose of antihypertensive drugs was reduced by 50%. [karger.com]
Workup
Further workup was consistent with primary pigmented nodular adrenal disease (PPNAD) without evidence of Carney Complex. A bilateral adrenalectomy was performed and the patient maintained on oral adrenal hormone replacement therapy. [digitalcommons.hsc.unt.edu]
MRI, with CSI, is also highly accurate in the workup of cortisol-secreting adrenal abnormalities. [doi.org]
Treatment
Management and treatment Bilateral adrenalectomy is the most common treatment for CS due to PPNAD followed by life-long cortisol and mineralocorticoid supplementation. Prognosis Without treatment, CS due to PPNAD can be life-threatening. [orpha.net]
Bilateral adrenalectomy is the treatment of choice. [ncbi.nlm.nih.gov]
Prognosis
Determine the prognosis for carriers and affected individuals. Provide sufficient data for genetic counseling of families with PPNAD and/or Carney Complex. ... [clinicaltrials.gov]
Prognosis Without treatment, CS due to PPNAD can be life-threatening. The documents contained in this web site are presented for information purposes only. [orpha.net]
Distinguishing between the isolated and syndromic variants of myxoma is essential as it has significant implications for patient management, prognosis and family screening. [doi.org]
MRI T1 lower signal intensity than surrounding atrophic adrenal tissue signal drop out demonstrated on out-of-phase imaging T2: lower signal intensity than surrounding atrophic adrenal tissue Treatment and prognosis The treatment of choice is bilateral [radiopaedia.org]
Etiology
Although rare, PPNAD should always be considered among the possible etiologies of CS, due to the high prevalence of this disease in this age group. [ncbi.nlm.nih.gov]
Etiology More than 90% of reported cases of PPNAD occur as one of the manifestations of Carney complex (CNC; see this term). Although rare, familial cases of isolated PPNAD have also been reported. [orpha.net]
To further determine the etiology of Cushing’s syndrome and localize the source of excess glucocorticoids production, additional studies were performed. [digitalcommons.hsc.unt.edu]
After this study, high dose dexamethasone suppression test was done to differentiate the etiology of Cushing’s syndrome. The levels of plasma cortisol were not suppressed and plasma ACTH level was very low. [doi.org]
Epidemiology
Summary Epidemiology The prevalence of endogenous Cushing syndrome (CS; see this term) is estimated at 1/26,000. PPNAD is responsible for less than 2% of cases. PPNAD is more frequent in females, especially after puberty. [orpha.net]
(See Epidemiology and DDx.) While myxomas are usually sporadic, several familial, autosomal dominant conditions that combine lentiginosis and cardiac myxomas have been described. [emedicine.medscape.com]

Pathophysiology
Diverse aberrant hormone receptors have been found to be implicated in the regulation of steroidogenesis and pathophysiology of AIMAH. PPNAD can be found alone or in the context of Carney complex, a multiple endocrine neoplasia syndrome. [ncbi.nlm.nih.gov]
Molecular studies of the tumors of the patients will provide additional clues for the pathophysiologic mechanisms leading to PPNAD/Carney complex. [clinicaltrials.gov]

Prevention
A paradoxical rise of urinary free cortisol (UFC) in response to dexamethasone is an early and specific laboratory marker of the disorder, allowing timely bilateral adrenalectomy which may not only prevent severe complications of hypercortisolism, but [jofem.org]
There is some evidence suggesting that statins can prevent osteonecrosis, but it is of note that our patient was never exposed to such treatment ( 19 ). [edmcasereports.com]
Women with Carney complex may be at a high risk for recurrent atrial myxomas that lead to multiple strokes. [22] Early identification of a female patient with Carney complex may facilitate stroke prevention. [emedicine.medscape.com]
The goals of this radiation therapy are to control pituitary hyper-secretion associated with minimal hypopituitarism, prevent future tumor growth, and possibly diminish tumor size. [doi.org]
The curative rate of PPNAD was about 30% by unilateral adrenalectomy, 60% by sub-total adrenalectomy, and nearly 100% by total adrenalectomy. 9 The Nelson syndrome could be prevented by routine dosage of adrenocor- ticosteroid replacement. 10 One case [124.205.33.103]
