L72.0 – Epidermal cyst
419893006 – Epidermoid cyst
Differential Diagnosis & Pitfalls
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.
