A lump on the buttocks may be a furuncle. Clinical manifestations and treatment of furuncle

A bag on the buttocks may seem like a trivial matter, and many people think that the bag will disappear automatically after a period of time. Little do people know that this small lump may worsen and even affect the health of other parts of the human body. If the lump on the buttocks is a boil, then it needs to be treated promptly. Below, we will introduce the clinical manifestations and treatment methods of furunculosis for your reference!

1. What is a boil?

Furuncle is a purulent infection of hair follicles and the surrounding tissues deep inside the hair follicles. A carbuncle is formed when multiple adjacent hair follicles are infected, inflamed and fused.

Staphylococcus aureus is the most common pathogen. Recurrent furunculosis in the anogenital area may be secondary to anaerobic infection. 5% are sterile and caused by a foreign body reaction, such as a ruptured cyst. It is more common in teenagers. Susceptibility factors include long-term carriage of S. aureus, diabetes, obesity, poor hygiene habits, and immunodeficiency status.

2. Clinical manifestations

Initially, small red, swollen and painful nodules appear locally, which gradually swell and become cone-shaped. After a few days, the center of the nodule becomes soft due to tissue necrosis, and small yellow-white pus plugs appear; the area of ​​redness, swelling, and pain expands. After a few more days, the pus plug falls off, the pus is discharged, and the inflammation gradually disappears and heals.

There are generally no obvious systemic symptoms. However, if it occurs in an area rich in blood and the body's resistance is weakened, it can cause symptoms of toxic blood such as discomfort, chills, fever, headache and anorexia. If boils on the face, especially around the upper lip and nose in the so-called "danger triangle", are squeezed or pricked, the infection can easily enter the cavernous sinuses in the skull along the medial angular vein and ophthalmic vein, causing suppurative cavernous sinusitis, with progressive redness, swelling and nodules extending to the eyes and surrounding tissues, accompanied by pain and tenderness, headache, chills, high fever and even coma. The condition is very serious and the mortality rate is very high.

3. Treatment

Inflammatory nodules can be treated with hot compresses or physical therapy (thermolysis, infrared or ultrashort wave), or with topical antibiotic ointments such as mupirocin ointment. When there is a pus head, apply carbolic acid on the top. When there is fluctuation, drainage should be performed as soon as possible. Immature boils should not be squeezed to avoid spreading the infection.

Antibiotics should be used systemically in the following four situations:

1. Folliculitis is located around the nose, in the nasal cavity or in the external auditory canal.

2. Large or recurrent furunculosis.

3. There is cellulitis around the lesions.

4. The skin lesions do not respond to local treatment.
