A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. [ 1 ] [ 3 ] It is considered to be benign since it does not spread beyond the bone. [ 4 ] Unicameral bone cysts can be classified into two categories: active and latent. [ 4 ]
Jaffé and Lichtenstein first coined the term "aneurismal cyst" in 1942 [11] In 1950 they modified this term to "aneurismal bone cyst". They may be associated with bone tumors. The simple bone cyst is a common, benign, fluid-containing lesion, most commonly found in the metaphysis of long bones, typically the proximal humerus or femur ...
Calcifying odontogenic cyst (COC) is a rare developmental lesion that comes from odontogenic epithelium. [2] It is also known as a calcifying cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass.
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
Osteitis fibrosa cystica (/ ˌ ɒ s t i ˈ aɪ t ɪ s f aɪ ˈ b r oʊ s ə ˈ s ɪ s t ɪ k ə / OSS-tee-EYE-tis fy-BROH-sə SIS-tik-ə) is a skeletal disorder resulting in a loss of bone mass, a weakening of the bones as their calcified supporting structures are replaced with fibrous tissue (peritrabecular fibrosis), and the formation of cyst-like brown tumors in and around the bone.
The lesion may arise de novo or may arise secondarily within a pre-existing bone tumor, because the abnormal bone causes changes in hemodynamics. An aneurysmal bone cyst can arise from a pre-existing chondroblastoma, a chondromyxoid fibroma, an osteoblastoma, a giant cell tumor, or fibrous dysplasia. A giant cell tumor is the most common cause ...
Over time, the cyst decreases in size and bone regenerates in the cavity space. Marsupialization could also be performed, which involves suturing the edges of the gingiva surrounding the cyst to remain open. The cyst then drains its contents and heal without being prematurely closed. The end result is the same as the cystostomy, bone regeneration.
The iliac fossa is bounded above by the iliac crest, and below by the arcuate line. It is bordered in front and behind by the anterior and posterior borders of the ilium. The iliac fossa gives origin to the iliacus muscle. [1] The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal.
