10 Common Types of Cysts
Type Of Cysts #2: Epidermoid Cyst
An epidermoid cyst is found on the skin. It develops out of ectodermal tissue and is histologically made of squamous epithelium. Although it is usually asymptomatic, the cyst can be tender (when touched). Epidermoid cysts are usually found on parts of the body with less hair.
Usually benign, there are also rare cases where malignant rumors arise from an epidermoid cyst. It is believed that it occurs when epidermis is implanted into the dermis due to surgery or trauma.
