A rare congenital anomaly presented as a finger-like protrusion from a baby's back. Surgical removal revealed it contained bone, cartilage, and skin, suggesting an ectopic finger and fingernail.

Area of Science:

  • Developmental biology
  • Pediatric surgery
  • Dermatology

Background:

  • Congenital anomalies present unique diagnostic and management challenges in pediatric surgery.
  • Cutaneous lesions at birth require thorough investigation to rule out underlying developmental abnormalities.

Observation:

  • A 7-month-old female infant presented with a finger-like appendage on her posterior thoracic region, noted since birth.
  • The 3 cm protrusion contained angiomatous and lipomatous tissue, with imaging revealing three bones and spinal dysraphism.
  • Histological examination confirmed the presence of nail, bone, cartilage, and skin within the appendage.

Findings:

  • The appendage was identified as a rare form of ectopic finger and fingernail, distinct from typical caudal appendages.
  • Imaging demonstrated a connection to the spinal cord, necessitating surgical intervention.

Related Experiment Videos

  • Surgical removal involved excision of the appendage and an intradural mass, along with laminectomy.

    • Implications:

    • This case highlights the importance of considering unusual presentations of congenital malformations.
    • Understanding the embryological basis of such ectopic structures is crucial for accurate diagnosis.
    • Surgical management aims to address both the external anomaly and potential neurological involvement.
