F1Ch36 (Q4897): A portion of a cyst is represented. Most of the keratinized debris is missing. The cyst is lined by stratified squamous epithelium. Near the bottom of the field, just to the left of center two sebaceous gland lobules are attached to the cyst; they partially interrupt the epithelial lining. In this relationship of gland to epithelial lining, the lumen of the cyst might be characterized as a distorted, and dilated, sebaceous duct. Blue arrows identify a portion of the epithelial lining with a distinctive corrugated surface. This corrugated surface, if represented and identified, is most characteristic of the epithelial lining of a steatocystoma. A thin layer of fibrous tissue supports the epithelial lining.
