Definition

keloidalis nuchae (AKN) is a skin condition characterized by the development of firm, raised scars (keloids) on the back of the neck, often as a result of folliculitis ( of hair follicles) and/or scarring from ingrown hairs. Acne keloidalis (AK) is a chronic skin condition characterized by the development of the firm, raised scars (keloids) on the back of the scalp, nape of the neck, and occipital area. It is a condition that typically affects men with tightly curled hair, although anyone can develop it.

The main cause of AKN is not entirely understood, but it is believed to be related to a combination of factors such as:

  • Friction: The constant rubbing of clothes against the skin can irritate hair follicles and lead to inflammation.
  • Irritation: The use of certain hair products or hairstyles that put pressure on the hair follicles can also lead to irritation.
  • : Bacteria can infect the hair follicles, leading to inflammation and scarring.
  • Hormonal imbalances: Hormonal fluctuations can increase the production of sebum, which can contribute to the development of AKN.
  • Genetics: Some people may be more susceptible to AKN due to factors.

Symptoms of AKN include:

  • Small, red, firm bumps on the back of the neck
  • Itchy or painful bumps
  • Inflamed, swollen bumps
  • Scabs or crusts on the bumps
  • Keloid-like scars that are firm, raised, and discolored
  • or in the affected area
  • or redness in the affected area

It’s important to note that AKN can be persistent and can be difficult to treat. It is also important to see a dermatologist for proper and treatment as some treatments may be more effective than others, depending on the individual case, and some may require multiple treatments.

Diagnosis of AK is typically made by a physical examination of the affected area. The doctor may also take a of the affected skin to rule out other conditions.

Treatment of AK typically involves a combination of approaches, including:

  • Topical medications: Topical retinoids, corticosteroids, and antibiotics may be used to reduce inflammation and prevent infection.
  • Oral medications: Oral antibiotics may be prescribed to reduce the growth of bacteria and reduce inflammation.
  • Cryotherapy: The use of liquid nitrogen to freeze and destroy the affected skin,
  • Surgery: Surgical removal of the keloids may be recommended in some cases, but it is important to note that there is a high risk of .
  • Scar management: Silicone gel sheeting or silicone gel can be applied to the scar to improve the appearance.
  • Preventive measures: Avoiding tight hairstyles, such as cornrows or braids, and avoiding friction and irritation on the scalp and nape of the neck.

It is important to see a dermatologist for proper diagnosis and treatment as AK can be persistent and can be difficult to treat. It is also important to note that some treatments may be more effective than others, depending on the individual case, and some may require multiple treatments.

It is also important to note that AK is a chronic condition and it may take multiple treatments to achieve good results, and even with successful treatment, the condition can recur.

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.
