From the Research
Definition and Characteristics
- Epidermal inclusion cysts are benign masses that often develop on the face, scalp, neck, and back, typically occurring secondary to acne or obstructed hair follicles 1
- They are characterized by a cyst wall composed of lamellate keratin and keratotic material internally 2
- Epidermal inclusion cysts can be distinguished from other conditions such as neurofibromatosis through physical examination and magnetic resonance imaging 2
Comparison with Mucous Cysts
- There is no direct comparison between mucous cysts and epidermal inclusion cysts in the provided studies
- However, it can be inferred that mucous cysts and epidermal inclusion cysts are distinct entities with different characteristics and origins
- Epidermal inclusion cysts are typically filled with keratotic material, whereas mucous cysts are filled with mucin 2, 1
Diagnosis and Treatment
- Epidermal inclusion cysts can be diagnosed through physical examination, magnetic resonance imaging, and histologic examination 2, 1
- The treatment of epidermal inclusion cysts typically involves complete excision, which is essential for their definitive treatment due to their ability to rupture, causing pain and infection 1
- Simple excision is often adequate for the treatment of epidermal inclusion cysts, especially when the diagnosis can be made confidently in the operating room 3
