POLAND SYNDROME

Introduction

Poland Syndrome is a relatively uncommon condition that involves various deformities. It is characterized by the congenital underdevelopment or absence of the bony and soft tissue structures of the chest wall, including the absence of the pectoralis major, pectoralis minor, and ribs. This can lead to abnormalities in the upper limb on the affected side, such as finger absence, syndactyly (fused fingers), brachydactyly (short fingers), and carpal hypoplasia, as well as in the breast and other areas.

Furthermore, Poland syndrome is more commonly seen on the right side, less frequently on the left side, with occasional cases involving both sides.

Causes

The exact cause of Poland syndrome remains unknown. It might be related to abnormal growth of the pectoral muscle bud during fetal development, disrupted blood supply to the chest wall during embryonic development, genetic factor, or other influences.

Symptoms

The typical symptoms include pectoral muscle deficiency, syndactyly, rib absence, breast defects, etc. Other symptoms like breathing difficulty and pectus excavatum may also develop. Without prompt treatment, the condition could lead to complications such as scoliosis, ventricular septal defect, and renal dysplasia.
