title: Pigmented follicular cysts.
abstract: This report deals with seven examples of an epithelial cyst for which we have found no proper designation in the classification of epithelial skin cysts. Clinically, the lesion is often hyperpigmented, located in mid-dermis and shows epidermoid keratinization. The cyst contains laminated keratin, many pigmented hair shafts and the cyst wall displays one or two growing hair follicles.
