[A neonate with unilateral paradoxical breathing]

Area of Science:

• Medicine
• Genetics
• Pediatrics

Background:

• Poland syndrome is a congenital condition characterized by unilateral hypoplasia or absence of the pectoral muscle.
• It is often associated with limb abnormalities, particularly on the same side of the body.

Observation:

• A one-day-old male neonate presented with noticeable asymmetry in thoracic excursions.
• The neonate did not exhibit any signs of respiratory distress.

Findings:

• The neonate was diagnosed with Poland syndrome based on clinical presentation.
• The condition involves an underdeveloped or absent pectoral muscle on one side of the chest.

Implications:

• While Poland syndrome can cause deformities, functional impairments are typically minor.
• Surgical reconstruction is an option for complex cases, but many patients maintain good function.
