A cyst found under the skin, usually in the midline, containing hair, sweat glands and sebaceous glands.
A cyst that is lined by skin. Dermoid cysts can contain a variety of tissues such as hair, sebaceous (oily) material, sweat glands, and, depending on where they occur in or on the body, even cartilage or bone. Dermoid cysts that occur in the ovary develop from embryo cells that can even grow teeth within the cyst. Dermoid cysts are usually benign (not cancerous). The most common locations for dermoid cysts are the eyebrows, nose, and scalp.
A cyst containing hair, hair follicles, and sebaceous glands, usually found at sites marking the fusion of developing sections of the body in the embryo. Sometimes a dermoid cyst may develop after an injury. Treatment is by surgical removal.
A dermoid cyst is a benign tumor that exhibits a cellular structure similar to that of the skin. Within this growth, one can find hairs, sweat glands, and sebaceous glands. Additionally, dermoid cysts may contain fragments of cartilage, bone, and even teeth. While these cysts can develop in various parts of the body, they are most commonly observed in the ovaries and on the skin around the head or neck, resulting in small, painless swellings. It is important to note that dermoid cysts rarely undergo malignant transformation.
In most cases, the recommended course of action for dermoid cysts is surgical removal.
While developing, the embryo starts as a flat sheet that folds into a tubular shape. Sometimes, cells get misplaced during this process and later evolve into a cyst. This cyst can include various tissue types from different parts of the body, like hair, teeth, cartilage, and bone.
