Cyst

A cyst is a closed pocket or pouch of tissue. It can be filled with air, fluid, pus, or other material.

Fibrocystic breast change

Fibrocystic breast change is a common and benign change within the breast characterized by a dense irregular and bumpy consistency in the breast tissue. Mammography or biopsy may be needed to rule out other disorders.

Pilonidal dimple

A pilonidal dimple is a small pit or sinus in the sacral area just at the top of the crease between the buttocks. The pilonidal dimple may also be a deep tract, rather than a shallow depression, leading to a sinus that may contain hair. During adolescence the pilonidal dimple or tract may become infected forming a cyst-like structure called a pilonidal cyst. These pilonidal cysts may require surgical drainage or total excision to prevent reinfection.
