It frequently consists of skin, hair follicles, and sweat glands, while other commonly found components include clumps of long hair, pockets of sebum, blood, fat, bone, nail, teeth, eyes, cartilage, and thyroid tissue.
Congenital dermal sinus is often also associated with spinal fluid drainage, intradural cysts and spinal cord tethering; conveying neurological deficit. [4] Neurological deficit can occur due to spinal cord compression from intradural dermoid cyst growth in the epidermis and dermis. [4]

Pseudocysts are like cysts, but lack epithelial or endothelial cells. Initial management consists of general supportive care. Symptoms and complications caused by pseudocysts require surgery. Computed tomography (CT) scans are used for initial imaging of cysts, and endoscopic ultrasounds are used in differentiating between cysts and pseudocysts.
Relative incidence of cutaneous cysts, where epidermoid cysts constitute a plurality (blue area). An epidermoid cyst or epidermal inclusion cyst [1] is a benign cyst usually found on the skin.
