- Infundibular cyst, sebaceous cyst, epidermoid cyst
Definitions
- Benign cyst originating in dermis lined with infundibular or epidermal-like cells that keratinize
- "Sebaceous cyst" is misnomer and should be avoided
- Cysts are not of sebaceous differentiation and imaging characteristics vary according to contents
