Sacrococcygeal hidradenitis

Pilonidal sinus disease (also known as pilonidal sinus disease) in the sacrococcygeal region is increasingly encountered in practice at specialized treatment facilities. Pilonidal cysts are skin depressions in the groove between the two buttocks and hair inside. Patients are usually between the ages of 15 and 30.

A proctologist said that pilonidal cyst (abscess, or sacrococcygeal fistula) is a type of cyst containing hair, hair and skin debris, which can be secondary infected in the buttock groove or sacrococcygeal area. Pilonidal cyst is a condition in which the hair follicles are infected, the cause can be congenital or acquired.

The "mechanism" that causes pubic hair growth in the coccyx area may be due to the movement of the buttocks creating a suction force that causes the hair to be sucked deep into the skin. However, there is also a view that due to the rubbing of the buttocks and the shearing force in the buttocks groove, the hair is drilled deep into the skin; or due to the hair breaking, falling out and concentrating in the buttocks groove...

The incidence of pilonidal cyst is 26/100,000; it is common in people aged 15-30 (with the impact of sex hormones on hair follicles), and is rare in people over 40 years old.

Pilonidal cysts can recur and cause complicated inflammation. It is important to distinguish pilonidal cysts from hidradenitis (often accompanied by pilonidal cysts), anal fistulas, syphilitic granulomas; osteomyelitis in the sacrum that leaks out of the skin; presacral cysts... Many cases of perianal pilonidal sinuses are similar to anal fistulas. High risk factors associated with pilonidal cysts include: obesity, poor hygiene; a history of folliculitis or boils in other areas of the body; people with hirsutism.

Doctors note that hidradenitis is becoming more common; there are many treatment methods, depending on the condition, but the wound is susceptible to infection and recurrence.
