Summary
This case study details an infant diagnosed with McCune-Albright syndrome, presenting with distinctive skin pigmentation and significant fibrous dysplasia of the bone. Early diagnosis is crucial for managing this rare genetic disorder.
Area of Science:
- Pediatric Endocrinology
- Dermatology
- Genetics
Background:
- McCune-Albright syndrome is a rare genetic disorder characterized by the triad of polyostotic fibrous dysplasia, café au lait spots, and precocious puberty.
- However, the presentation can be variable, with some patients exhibiting only a subset of these classic features.
Observation:
- A 7-week-old infant presented with hyperpigmented macules (café au lait spots) noted from 5 days of age.
- At 15 months, the infant developed a limp, and radiographic evaluation revealed widespread bilateral fibrous dysplasia, particularly affecting the pelvis, femur, and tibia.
Findings:
- Histopathological examination of skin lesions confirmed epidermal melanosis consistent with café au lait spots.
- Despite the absence of endocrine abnormalities, the combination of extensive cutaneous and bony lesions strongly suggested McCune-Albright syndrome.
Implications:
- This case highlights the importance of recognizing McCune-Albright syndrome even in the absence of typical endocrine manifestations.
- Early identification of cutaneous and skeletal abnormalities is critical for timely diagnosis and management of McCune-Albright syndrome.
