The majority of epidermal inclusion cysts originate from the infundibular portion of the hair follicle, thus explaining the interchangeable, [14] yet inaccurate, use of these two terms. Epidermoid cyst may be classified as a sebaceous cyst , [ 15 ] although technically speaking it is not sebaceous. [ 16 ] "
A sebaceous cyst is a term commonly used to refer to either: [1] Epidermoid cysts (also termed epidermal cysts, infundibular cyst) Pilar cysts (also termed trichelemmal cysts, isthmus-catagen cysts) Both of the above types of cysts contain keratin, not sebum, and neither originates from sebaceous glands.

Specialty: General surgery, infectious disease, dermatology: Symptoms: Redness, pain, swelling [1] Usual onset: Rapid: Causes: Bacterial infection (often MRSA) [1] Risk factors: Intravenous drug use [2] Diagnostic method ...
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 the "shell" of such a sac are distinctly abnormal (in both ...
Epidermoid tumors strongly adhere to the brain stem or cranial nerves. Often the lining of the tumor connected to the brain stem or parts difficult to "peel" away are left behind leaving residual tumor after surgery, this can contribute to the risk of regrowth. About 40% of these cysts originate in the cerebellopontine angle. [3]
An epithelial inclusion cyst is also referred to as epidermal inclusion cyst or squamous inclusion cyst. [22] [10] This type of cyst comprises 23% of all vaginal cysts and is the second most common. This cyst originates from epithelium tissue that has been 'trapped' from surgery, episiotomy, or other trauma. It is most often found on the lower ...
