An unusual congenital leiomyoma
Pediatric Dermatology
|February 1, 1986
Summary
Congenital cutaneous leiomyomas are rare skin tumors. This case report details an unusual infant heel mass, identified as a congenital smooth muscle anomaly.
Area of Science:
- Dermatology
- Pathology
- Pediatrics
Background:
- Cutaneous leiomyomas are typically acquired benign tumors arising from arrector pili muscles.
- They usually present as discrete, painful papules or nodules in adults.
- Congenital presentation is exceptionally rare.
Observation:
- An infant presented at birth with a large, unusual mass on the right heel.
- The mass was a solitary, firm lesion with normal overlying skin.
- No other congenital anomalies were noted.
Findings:
- Histopathological examination confirmed the lesion to be a leiomyoma.
- The tumor exhibited features of smooth muscle proliferation.
- Immunohistochemical analysis supported the smooth muscle origin.
Implications:
- This case highlights a rare instance of congenital cutaneous leiomyoma.
- It suggests a potential for unusual smooth muscle anomalies during fetal development.
- Further research into the embryogenesis of such lesions is warranted.
