Abstract
Epidermoid bone cyst is an intramedullary, unilocular cyst lined by squamous epithelium containing keratin, with greater incidence in males. These acral lesions (common in manual workers) present from the third to sixth decades of life. Skull lesions are more frequent in the first decade. Excluding the epithelium-lined cyst of jaws, epidermoid cysts are located almost exclusively in the distal phalanges, followed by the frontal and parietal regions of the skull. Roentgenographically, it is a well-defined, round, osteolytic lesion. The inner lining of the cyst consists of squamous malpighian epithelium with a granulosa layer covered by laminated masses of keratin that fill the cavity. Treatment includes curettage or excision of the phalanx lesion or skull cysts.
