Familial endocrine myxolentiginosis is a rare genetic disorder characterized by cardiac myxomas and other tumors. Early diagnosis via transesophageal echocardiography is crucial for managing this condition.
Area of Science:
- Endocrinology
- Cardiology
- Genetics
Background:
- Familial endocrine myxolentiginosis is a rare genetic disorder.
- It is characterized by a spectrum of tumors and nevi.
Observation:
- Presents with cardiac myxomas, cutaneous myxomas, lentigines/blue nevi, adrenal hyperplasia, and various tumors.
- Cardiac myxomas share features with familial cardiac myxoma: early onset, atypical locations, multicentric origins, and recurrence.
Findings:
- A new syndrome, familial endocrine myxolentiginosis, is proposed.
- Diagnosis requires two or more clinical features; definitive diagnosis with three or more.
- A Venn diagram classification for cardiac myxomas is suggested.
Implications:
- Early diagnosis of this underdiagnosed entity is possible with transesophageal echocardiography.
- Recognition is vital due to clinical, surgical, and genetic implications.
- Clinicians should consider this syndrome in differential diagnoses.

The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
