Epidermal inclusion cysts are the most common cysts of the skin. They are more likely to occur on the face, scalp, neck and trunk due to the migration of epidermal components to the dermis. Those small, slow-growing benign tumors rarely reach more than 5 cm in diameter. For this reason, epidermal cysts are mostly diagnosed clinically and imaging is rarely performed. However, we describe a case of a giant epidermal cyst bordered between the anal and gluteal region which is considered to be a rare localization. To determine its exact size, nature and relationships with the neighboring organs using MRI was very essential (1,2,3,4).
