Branchial cleft cyst
|
|
Branchial cleft cystAlso called a branchial cyst, this is a cavity that is a remnant from embryologic development present at birth in one side of the neck just in front of the large angulated muscle on either side (the sternocleidomastoid muscle). The cyst may not be recognized until adolescence as it enlarges its oval shape. Sometimes it develops a sinus or drainage pathway to the surface of the skin from which mucus can be expressed. Total surgical excision is the treatment of choice. Recurrence is not expected.
RELATED TERMS--------------------------------------
Cyst
A soft or hard tissue sac, hard or filled with fluid
Cavity
A hollow place or hole within the body.
Development
The process of growth and differentiation.
Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.
Sinus
Paranasal sinuses. Air cavities within the facial bones, lined by mucous membranes similar to those in other parts of the airways.
Skin
Skin is an organ of the integumentary system; which is composed of a layer of tissues that protect underlying muscles and organs. Skin is used for insulation, vitamin D production, sensation, and excretion (through sweat).
Mucus
A substance secreted by various tissues in the body (the mucous membranes) made up of water, mucin (a glycoprotein), salts, and some cells. In the lungs, mucus serves to lubricate the insides of the airways and to trap inhaled foreign particles so that they can be coughed out. In asthma, however, an excess of mucus is produced and can actually block airways. Mucus also tends to be thicker and more viscous in asthmatics.
Excision
1. Surgical removal, as in the excision of a tumor. 2. The removal as if by surgery, as in base excision repair.
Recurrence
The return of symptoms or the tumor itself, as opposed to a remission.

PREVIOUS AND NEXT TERMS--------------------------------------
Brain, fornix of the
An arching fibrous band in the brain connecting the two lobes of the cerebrum. (The cerebrum is the largest part of the brain and consists of two hemispheres separated by a deep longitudinal fissure). Each fornix -- there are two -- in the brain is an arched tract of nerves.
Brainerd diarrhea
A syndrome characterized by the acute onset of watery nonbloody diarrhea (3 or more loose stools per day), lasting 4 weeks or more, and resolving spontaneously. The disease is of unknown causation and appears in outbreaks or as sporadic cases.
Brainstem
The lowest part of the brain which merges with the spinal cord and provides the major route by which the upper realms of the brain send information to, and receives information from, the spinal cord and peripheral nerves. The brainstem consists of the medulla oblongata, midbrain, and pons. All but two of the 12 cranial nerves originate in the brainstem. The brainstem influences basic processes such as alertness, breathing, blood pressure, and heart rate.
Brainstem auditory evoked potentials
See: ABR test.
Brainstem implant
A type of hearing aid that bypasses the cochlea in the middle ear and the auditory nerve and is implanted in the brainstem. This type of implant helps individuals who cannot benefit from a cochlear implant because the auditory nerves are not working.

Brazelton newborn test
A widely used test of the newborn baby as to their neurologic status and developmental progress.
BRCA breast cancer gene
One of several genetic mutations linked to breast cancer and ovarian cancer. There is now convincing evidence that every woman with a BRCA mutation is at high risk for breast cancer, irrespective of whether she has a family history of breast cancer or not. By age 80, a woman with a BRCA mutation has about an 80% chance of developing breast cancer. BRCA1 and BRCA2 increase the risk of ovarian cancer 54% and 23%, respectively. Mutations in BRCA1 or BRCA2 account for 5-10% of all breast cancer which translates into 10-20,000 new cases of breast cancer in the US and many more around the world every year.
BRCA1 breast cancer susceptibility gene
A mutated (changed) version of the BRCA1 gene that makes a person susceptible to developing breast cancer.
BRCA2
A gene that normally acts to restrain the growth of cells in the breast and ovary but which, when mutated, may predispose to breast cancer and to ovarian cancer. BRCA2 mutations have also been discovered to be responsible for a significant fraction of early-onset prostate cancer. The first breast cancer genes identified were BRCA1 and BRCA2. Mutations of BRCA1 and BRCA2 account for about half of all cases of inherited breast cancer. These tumors tend to occur in young women. BRCA1 and BRCA2 are usually not involved in breast cancer that is not hereditary.
