Insights
Congenital synmastia, a rare pediatric breast anomaly, typically lacks an intermammary sulcus. This report details the first case of congenital synmastia co-occurring with multiple fibroadenomas in a pediatric patient.
Area of Science:
- Pediatric Surgery
- Breast Surgery
- Congenital Anomalies
Background:
- Congenital synmastia, absence of the intermammary sulcus, is a rare pediatric breast anomaly.
- Acquired synmastia post-augmentation is documented, but congenital cases are exceptionally rare, with only four previously reported.
- This study presents the first documented case of congenital synmastia concurrently with multiple fibroadenomas.
Abstract:
Congenital synmastia, or absence of the intermammary sulcus, is a rare breast anomaly in the pediatric population. While acquired synmastia after breast augmentation is a well-documented entity, congenital synmastia is a rare condition with only four previous cases reported in the surgical literature. We describe the first patient with concurrent presentation of congenital synmastia and multiple fibroadenomas. A combined technique was used to both address the patient's breast lesions and correct the defect.

There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
