Poland's Syndrome with Absent Limb Anomalies

Area of Science:

• Medical genetics
• Pediatric surgery
• Congenital malformations

Background:

• Poland syndrome is a rare congenital disorder characterized by underdevelopment or absence of chest muscles, typically the pectoralis major.
• It can also involve abnormalities of the ribs, breast, and upper limb on the affected side.
• The spectrum of Poland syndrome ranges from mild to severe, impacting various anatomical structures.

Observation:

• A neonate presented with a depressed right chest wall without respiratory distress.
• Computed tomography revealed hypoplasia of the right pectoralis major muscle and reduced subcutaneous fat.
• Associated findings included abnormalities of the ipsilateral ribs, but no upper limb deformities were noted.

Findings:

• The neonate exhibited a distinct presentation of Poland syndrome, primarily affecting the chest wall.
• The absence of upper limb deformities in this case broadens the known clinical spectrum of the condition.
• Genetic or environmental factors may contribute to the variable expressivity of Poland syndrome.

Implications:

• This case underscores the importance of recognizing the diverse clinical manifestations of Poland syndrome.
• Accurate diagnosis and understanding the spectrum are crucial for appropriate management and genetic counseling.
• Further research into the etiology and phenotypic variability of Poland syndrome is warranted.
