Is Carney complex rare?
Carney complex is a rare genetic disorder characterized by multiple benign tumors (multiple neoplasia) most often affecting the heart, skin and endocrine system and abnormalities in skin coloring (pigment) resulting in a spotty appearance to the skin of affected areas.
What is Carney triad?
Carney triad is a rare condition that describes the occurrence of three kinds of endocrine tumors in the same child. The tumors comprising the triad are tumors in the gastrointestinal tract (known as gastrointestinal stromal tumors, or GIST), pulmonary chondromas, and paragangliomas.
How many people have Carney complex?
Carney complex is very rare. Fewer than 500 cases have been reported worldwide. It is estimated that between 50% and 70% of cases of Carney complex run in families. The remaining 30% to 50% of cases appear to be sporadic (occurs by chance) and may be due to a de novo (new) gene mutation.
What is Lamb Syndrome?
LAMB syndrome. Specialty. Oncology, cardiology. Carney complex and its subsets LAMB syndrome and NAME syndrome are autosomal dominant conditions comprising myxomas of the heart and skin, hyperpigmentation of the skin (lentiginosis), and endocrine overactivity.
What is name syndrome?
NAME syndrome: Acronym for Nevi, Atrial myxoma, Myxoid neurofibroma, and Ephelides. Now included in the Carney complex. See: Carney complex.
What is cutaneous myxoma?
Cutaneous myxoma, also known as superficial myxoma or superficial angiomyxoma, is a rare myxoid tumor of the skin and subcutis. Cutaneous myxomas are histologically identical to the cutaneous myxoid tumors seen in patients with Carney’s syndrome, although most occur sporadically.
Are myxomas hereditary?
About 1 in 10 myxomas are passed down through families (inherited). These tumors are called familial myxomas. They tend to occur in more than one part of the heart at a time, and often cause symptoms at a younger age.
What syndrome is atrial myxoma?
Myxoma syndromes include: LAMB (lentigines, atrial myxomas, mucocutaneous myxomas, and blue naevi) NAME (naevi, atrial myxomas, myxoid neurofibroma, and ephelides (freckles)) Carney syndrome (atrial, cutaneous and mammary myxomas, lentigines, blue naevi, endocrine disorders and testicular tumours)
What causes Lamb Shaffer syndrome?
Genetics. This condition is caused by mutations in the SRY-related HMG-box (SOX5) gene. This gene encodes a protein in the family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The gene is located on the short arm of chromosome 12 (12p12).
What is atrial myxoma with Lentigines?
What is myxoma syndrome? Myxoma syndrome is the name given to a group of diseases that are characterised by the presence of atrial myxomas (tumours of heart tissue) and lentigines (pigmented spots on the skin).
What is Carney’s triad?
Disease definition. Carney’s triad is a rare non-hereditary condition characterized by gastrointestinal stromal tumors (GIST, intramural mesenchymal tumors of the gastrointestinal tract with neuronal or neural crest cell origin), pulmonary chondromas and extraadrenal paragangliomas.
What is the prognosis of Carney’s triad with Gist?
GIST associated with Carney’s triad are mostly indolent. Recurrence after surgery is found in approximately 50% of patients, with a mean interval after the initial presentation of 12 years. Imatinib mesylate, an effective agent in the treatment of GIST, is under investigation as an adjuvant treatment.
What is the treatment of choice for Carney-Stratakis dyad?
The differential diagnosis should include Carney-Stratakis dyad. The treatment of choice for GIST and its metastases (overall rate: 50%) is surgical resection. GIST associated with Carney’s triad are mostly indolent. Recurrence after surgery is found in approximately 50% of patients, with a mean interval after the initial presentation of 12 years.
