Carney's complex

(redirected from Mammary myxoid fibroma)

Carney syndrome

An autosomal dominant multiple neoplasia and lentiginosis syndrome, first described as the association of:
(1) primary pigmented nodular adrenocortical disease (PPNAD), a pituitary-independent, primary form of hyperadrenocortisolism;
(2) lentigines, freckles, and blue nevi of skin and mucosae; and
(3) nonendocrine and endocrine tumours, including myxomas of skin, heart, breast, and other sites; tumours of thyroid, ductal adenoma of breast; psammomatous melanotic schwannoma; growth hormone-producing pituitary adenoma; testicular Sertoli-cell tumour; and acromegaly due to somatomammotroph hyperplasia and growth hormone-releasing, hormone-independent adenoma.

Molecular pathology
Most cases (70%) of Carney syndrome are due to an inactivating mutation in PRKAR1A on chromosome 17q23-q24, which is thought to encode a tumour-suppressor gene.

Carney complex (≥ 3 of the following)
Cardiac myxoma
Cutaneous myxoma
Mammary myxoid fibroma 
Spotty mucocutaneous pigmentation
Lentigines—blue, junctional or compound nevi
Primary pigmented nodular adrenocortical disease
Testicular tumour—large cell calcifying Sertoli cell tumours, often bilateral/multicentric
Pituitary hGH-secreting tumour—acromegaly or gigantism
An autosomal dominant [MIM 160980] clinical triad of young adult onset, which consists of spotty mucocutaneous Lentigenes, cutaneous and cardiac—Atrial Myxomas—and Blue nevi, endocrine hyperactivity, multifocal myxoid fibroadenomas of breast, adrenocortical hyperplasia and calcifying Sertoli cell tumours of testes
