Differential Diagnosis & Pitfalls
Epidermoid cysts are rare before puberty, and alternative diagnoses should be strongly considered in infancy and childhood.Superficial lymph nodes are palpated within the subcutaneous fat and are found within the course of lymphatics.
- Dermoid cysts result from anomalies in embryonic closure zones. Surgical removal or biopsy of a cyst over the midline should not be attempted without proper imaging to rule out intraspinal or intracranial connection.
- Thyroglossal duct cysts present as midline cystic nodules on the neck in children.
- Branchial cleft cysts present in the second or third decade as a nodule in the preauricular area, mandibular region, or along the anterior border of the sternocleidomastoid muscle.
- Bronchogenic cysts are most frequently found in the suprasternal notch, and they represent sequestered respiratory epithelium during embryological development.
- Lipomas are soft, mobile subcutaneous nodules with normal overlying epidermis.
