Technically speaking, then, they are not sebaceous cysts. [2] "True" sebaceous cysts, which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have suggested that the term "sebaceous cyst" be avoided since it can ...
A cyst is related to an abscess, but it contains a material other than pus, and a cyst has a clearly defined wall. Abscesses can also form internally on internal organs and after surgery. They are usually caused by a bacterial infection. [10] Often many different types of bacteria are involved in a single infection. [8]
In case of a persistent infection, infection drainage is performed during the excision operation. The operation is generally performed by an appropriately trained specialist surgeon e.g. an otolaryngologist or a specialist General Surgeon. The fistula can be excised as a cosmetic operation even though no infection appeared.
If there is infection, treatment is generally by incision and drainage just off the midline. [1] [2] Shaving the area and laser hair removal may prevent recurrence. [1] [4] More extensive surgery may be required if the disease recurs. [1] Antibiotics are usually not needed. [2] Without treatment the condition may remain long term. [1]
Epidermoid cyst may be classified as a sebaceous cyst, [15] although technically speaking it is not sebaceous. [16] "True" sebaceous cysts, cysts which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have ...
Sebaceous cyst is a term used to refer to both an epidermoid cyst and a pilar cyst, though neither of these contain sebum, only keratin and do not originate in the sebaceous gland and so are not true sebaceous cysts. A true sebaceous cyst is relatively rare and is known as a steatocystoma. [38]
The cyst can also become infected and form an abscess, or a painful, puss-filled pocket. Once branchial cysts begin growing, doctors will advise immediate removal to prevent further infection.
True" sebaceous cysts, which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have suggested that the term "sebaceous cyst" be avoided since it can be misleading. [8]: 31 In practice, however, the term is still ...
