Steatocystoma is a rare benign dermal cyst.
General
- Benign.
- Typically adults.
- Usually on the trunk.
- May be genetic; known as steatocystoma multiplex.[1]
- Classically autosomal dominant.[2]
Microscopic
Features:[3]
- Cyst lined by squamous epithelium with:
- Corrugated eosinophilic lining - key feature.
- Similar appearance to compact keratin (hyperkeratosis).
- Described as a hyaline cuticle.[4]
- No granular cell layer.
- Corrugated eosinophilic lining - key feature.
