[Multiple lentiginosis and hypertrophic obstructive cardiomyopathy]
Insights
Multiple Lentiginosis (ML) patients can develop severe heart problems, specifically obstructive hypertrophic cardiomyopathy affecting both ventricles. This heart condition may significantly influence the overall clinical presentation of ML syndrome.
Area of Science:
- Cardiology
- Genetics
- Dermatology
Background:
- Multiple Lentiginosis (ML) is a rare genetic disorder characterized by skin pigmentation and various systemic anomalies.
- Hypertrophic cardiomyopathy, particularly outflow tract obstruction, is a known complication in some ML patients.
Observation:
- Two patients with ML presented with hypertrophic cardiomyopathy causing severe obstruction in both the right and left ventricular outflow tracts.
- The study critically examined existing literature and clinical observations regarding ML and cardiac involvement.
Findings:
- Biventricular obstructive hypertrophic cardiomyopathy was observed in the patients with ML.
- This specific cardiac manifestation appears to be a significant factor in the clinical spectrum of ML.
Implications:
- The findings suggest a strong association between ML and biventricular obstructive hypertrophic cardiomyopathy.
- Recognizing this association is crucial for comprehensive patient management and understanding the pathophysiology of ML syndrome.
Abstract:
Two patients with Multiple Lentiginosis (ML) had hypertrophic cardiomyopathy with severe obstruction of the right and left ventricular outflow tracts. ML is a rare syndrome in which there is a typical skin pigmentation disorder together with various other abnormalities like slight mental retardation, sensorineural deafness, genital and skeletal anomalies and sometimes a characteristic facies. Obstruction of the right ventricular outflow tract is frequent in such patients. The association of ML and obstructive hypertrophic cardiomyopathy has been recently reported. A critical examination of the literature in addition to our clinical observations suggests that the biventricular obstructive hypertrophic cardiomyopathy may play a major role in the clinical feature of ML syndrome.
