Pilar cysts? - pilar cyst
I wonder if anyone had any cysts column. I have in my scalp, not surprising because they have thicker hair, but they are a nuisance and can be sensitive and painful. I have some retired, but still. These are just little bumps and I obviously can not get everything all the time you remove a lot of time and money and Surgery! Does anyone have to bring with them?

Pilar cysts are common and occur in 5-10% of the population. They are the second keratinizing cyst on the scalp. The benign and malignant degeneration is extremely rare. Inheritance is autosomal dominant in a. Column or Trichilemmal Cyst cysts contain keratin and its breakdown products, from a wall as the external (non-surround), the sheath of the hair root. Most Pilar cysts occur on the scalp.
Can result in 2% of Pilar Cyst Pilar, one or more foci of cell proliferation, the rare cases of tumor dissemination, more often than the spread of Trichilemmal Cyst cysts were observed. Originally they were as evil, however, felt that Wilson Jones pseudocarcinomatous. Trichilemmal Cyst growth is rapidly growing tumors, which often can Trichilemmal Cyst cysts occur, however, de novo, without a pre-existing injury. The tumors can be large and ulcerated. Although biologically benign, the cysts can be locally aggressive. In rare cases, malignant transformation orccurred, as well as distant metastases. No reliable clinical criteria exist to distinguish malignant from benign tumors spread of Pilar. Any violation should be examined histologically to assess the possibility of malice.
Pathophysiology: Trichilemmal Cyst cysts from the outer root sheath of hair follicles. Its origin is unknown, but it has been proposed to occur by budding of the outer root sheath as a structural genetic aberrations. They occur mainly in areas of dense concentrations of follicle, ie 90% of cases occur in the scalp. They are in 30% of cases, solitary and multiple in 70% of cases.
Histologically, areas in which evidence of the spread can be found in some cysts. In rare cases, this leads to tumor formation known as Proliferating Trichilemmal Cyst. The numbers of tumor clinically benign, but may show nuclear atypia, dyskeratotic cells and mitotic. These properties can be misleading, and a diagnosis of squamous cell carcinoma could be inaccurateur offer.
Frequency:
In the United States: Pilar cysts are common, occurring in 5-10% of the population. Among the patients with these cysts, 70% have multiple lesions and 10% are injured more than 10.
Mortality and morbidity: Pilar cysts are to be biologically benign, but may locally aggressive. Malignant transformation occurred in rare cases, as shown distant metastases.
