Carney Complex (CNC) diagnostic criteria proposed by Stratakis, Kirschner, and Carney (2001)
Features | Present case |
---|---|
Diagnostic criteria | |
1. Spotty skin pigmentation with a typical distribution (lips, conjunctiva and inner or outer canthi, vaginal and penile mucosa) | Absent |
2. Myxoma (cutaneous and mucosal)a | Present (two cutaneous and two mucosal myxomas) |
3. Cardiac myxomaa | Present |
4. Breast myxomatosisa or fat-suppressed magnetic resonance imaging findings suggestive of this diagnosis | Absent |
5. PPNADa or paradoxical positive response of urinary glucocorticosteroids to dexamethasone administration during Liddle’s test | Absent |
6. Acromegaly due to GH-producing adenomaa | Present |
7. LCCSCTa or characteristic calcification on testicular ultrasonography | Not applicable |
8. Thyroid carcinomaa or multiple, hypoechoic nodules on thyroid ultrasonography, in a young patient | Absent |
9. Psammomatous melanotic schwannomaa | Absent |
10. Blue nevus, epithelioid blue nevus (multiple)a | Absent |
11. Breast ductal adenoma (multiple)a | Absent |
12. Osteochondromyxomaa | Absent |
Supplemental criteria: | |
1. Affected first-degree relative | Absent |
2. Inactivating mutation of the PRKAR1A gene | Not evaluated |
To confirm a diagnosis of CNC, a patient must either: (1) exhibit two diagnostic features or (2) exhibit one diagnostic feature and one of the supplemental criteria [1]
aMicroscopically confirmed. GH growth hormone, LCCSCT large cell-calcifying Sertoli cell tumor, PPNAD primary pigmented nodular adrenocortical disease
