Acne Miliaris Necrotica

Acne miliaris necrotica also known as “neutrophilic folliculitis, is a rare form of acne that typically affects the cheeks and nose. It is characterized by small, red or yellow papules (bumps) that are often surrounded by a halo of redness. The condition is thought to be caused by a blockage of the hair follicles, which leads to inflammation and the formation of small, necrotic (dead) areas in the skin. It is typically treated with topical or oral antibiotics, as well as topical retinoids. In some cases, isotretinoin may be used to help reduce the size of the affected area and improve the appearance of the skin.

Acne miliaris necrotica (AMN) is a rare and benign condition that affects the hair follicles of the face, particularly the cheeks and nose. The exact cause of AMN is not well understood, but it is thought to be related to a combination of genetic and environmental factors.


One theory is that AMN is caused by an abnormal response of the immune system to the presence of Propionibacterium acnes, a type of bacteria that is normally present on the skin. This leads to the formation of small, red, raised bumps on the skin that are filled with pus.

Acne miliaris necrotica (AMN) is a rare type of acne that primarily affects the cheeks and nose. The exact cause of AMN is not fully understood, but it is thought to be related to the overproduction of oil (sebum) in the skin.

Some possible causes of AMN include:

  • Hormonal changes: Hormonal fluctuations, such as those that occur during puberty or pregnancy, can increase sebum production and lead to the formation of AMN.
  • Genetics: Some studies suggest that AMN may be inherited, as it tends to run in families.
  • Bacterial overgrowth: The presence of certain types of bacteria, such as Propionibacterium acnes, can lead to the formation of AMN.
  • Medications: Certain medications, such as corticosteroids and lithium, can increase the risk of developing AMN.
  • Environmental factors: Exposure to certain environmental irritants, such as wind and cold, can increase the risk of developing AMN.

It’s important to note that AMN is a rare and benign condition that usually resolves on its own. However, if you have AMN, it’s important to see a dermatologist as they can recommend appropriate treatment options.


The symptoms of AMN include:

  1. Small, red, and tender bumps: The bumps are typically less than 1 cm in diameter and are usually located on the cheeks, forehead, and chin.
  2. Pustules: The bumps may also contain a yellow or white center, which is a sign of inflammation and infection.
  3. Blackheads: AMN is often accompanied by the formation of blackheads, which are clogged pores filled with sebum and dead skin cells.
  4. Scarring: In severe cases, AMN may lead to scarring of the skin, which can be permanent.
  5. Itching and burning: Some individuals may experience itching and burning sensations around the affected areas.
  6. Inflammation: The surrounding skin may appear red and swollen.
  7. Fatigue: Individuals may feel fatigued, and have a general feeling of malaise.

It’s important to note that AMN is not contagious and does not pose any serious health risks. However, it can cause emotional distress and self-esteem issues. Consultation with a dermatologist is highly recommended if you suspect you have AMN.


The diagnosis of AMN is typically made through a physical examination of the affected area. A skin biopsy may be performed to confirm the diagnosis and rule out other potential causes of the symptoms.


Treatment for acne miliaris necrotica typically involves a combination of topical and oral medications. The specific treatment plan will depend on the severity of the condition and the individual patient’s needs.

Topical treatments may include:

  • Retinoids, such as tretinoin or adapalene, to unclog pores and reduce inflammation
  • Antibiotics, such as clindamycin or erythromycin, to reduce bacterial growth and prevent infection
  • Steroids, such as hydrocortisone, to reduce inflammation and redness

Oral medications may include:

  • Antibiotics, such as tetracyclines or minocycline, to reduce bacterial growth and prevent infection
  • Isotretinoin, a powerful oral retinoid, to unclog pores and reduce inflammation

In addition to these medications, patients are often advised to avoid harsh skin care products and to use a gentle, non-comedogenic moisturizer to help keep the skin hydrated.

It is important to note that treatment for acne miliaris necrotica may take several weeks or months to see significant improvement, and some patients may experience worsening of their symptoms before they improve. Close monitoring by a dermatologist is crucial for the management of this condition.
