Perifolliculitis Capitis Abscedens Et Suffodien: Symptoms, Causes and Treatment

Written by Medicover Team and Medically Reviewed by Dr Anusha Nagral Reddy , Dermatologists



Perifolliculitis capitis abscedens et suffodiens is a rare and chronic inflammatory condition that affects the hair follicles on the scalp. Also known as dissecting cellulitis of the scalp, it can cause painful lesions, abscesses, scarring, and permanent hair loss if left untreated. Early diagnosis and appropriate treatment can help control inflammation, prevent progression, and reduce complications.


What are the Types of Perifolliculitis Capitis Abscedens Et Suffodiens?

Perifolliculitis capitis abscedens et suffodiens is generally considered a chronic inflammatory scalp disorder rather than a condition with well-defined clinical subtypes. The severity and depth of follicular involvement can vary, and related follicular occlusion disorders may have similar features.

  • Superficial involvement: Inflammation primarily affects the upper portion of the hair follicles and may present with smaller pustules or inflamed areas.
  • Deep involvement: Inflammation extends deeper into the hair follicles and surrounding tissues, resulting in painful nodules and abscesses.
  • Dissecting cellulitis of the scalp: The severe, interconnected inflammatory lesions associated with perifolliculitis capitis abscedens et suffodiens can form sinus tracts, abscesses, and areas of scarring alopecia.

What are the Symptoms of Perifolliculitis Capitis Abscedens Et Suffodiens?

Perifolliculitis capitis abscedens et suffodiens, also known as dissecting cellulitis of the scalp, typically causes painful, recurrent inflammatory lesions on the scalp. Symptoms may gradually worsen and can result in scarring and permanent hair loss when the condition is not adequately treated.

  • Severe scalp pain: Persistent or throbbing pain in affected areas, which may worsen with pressure or touch.
  • Pus-filled bumps: Inflamed nodules or pustules may contain pus and can rupture and discharge fluid.
  • Scalp tenderness and swelling: The affected scalp may become swollen, sensitive, and inflamed.
  • Abscess formation: Deep, interconnected abscesses may develop beneath the scalp and can form sinus tracts.
  • Scarring: Chronic inflammation can cause thickened or scarred areas of the scalp.
  • Hair loss: Destruction of hair follicles can result in permanent hair loss, known as scarring alopecia.
  • Foul-smelling discharge: Ruptured lesions may release purulent material with an unpleasant odor.

What are the Causes and Risk Factors of Perifolliculitis Capitis Abscedens Et Suffodiens?

The exact cause of perifolliculitis capitis abscedens et suffodiens is not fully understood. It is believed to involve abnormal blockage and inflammation of hair follicles, followed by follicular rupture and an inflammatory response. It belongs to the follicular occlusion spectrum of disorders.

  • Follicular occlusion: Blockage of hair follicles by keratin and other follicular material may contribute to inflammation and follicle rupture.
  • Immune system dysfunction: Abnormal inflammatory responses may contribute to persistent inflammation and delayed healing.
  • Genetic predisposition: A family or genetic tendency may increase susceptibility to follicular occlusion disorders.
  • Hormonal influences: Androgen-related factors may contribute to follicular activity and inflammation in susceptible individuals.
  • Secondary bacterial infection: Bacteria may colonize or infect damaged follicles and worsen inflammation or abscess formation.

Several factors may increase the risk or severity of the condition:

  • Male sex and young adulthood
  • Obesity
  • Smoking
  • Chronic scalp irritation
  • Family history of similar inflammatory skin conditions

When to See a Doctor?

Consult a dermatologist or healthcare provider if you develop persistent or worsening scalp symptoms that may indicate perifolliculitis capitis abscedens et suffodiens.

  • Painful or recurrent bumps and nodules on the scalp
  • Pus-filled lesions, abscesses, or foul-smelling discharge
  • Scalp tenderness, swelling, or increasing hair loss

Get medical help immediately if:

  • Rapidly spreading painful abscesses or severe scalp inflammation
  • Fever or other signs of a significant infection
  • Extensive scalp damage or rapidly progressing hair loss

Early medical evaluation and treatment can help control inflammation and reduce the risk of permanent scarring and hair loss.

How Is Perifolliculitis Capitis Abscedens Et Suffodiens Diagnosed?

Diagnosis of perifolliculitis capitis abscedens et suffodiens, also known as dissecting cellulitis of the scalp, is primarily based on the appearance of the scalp lesions, medical history, and clinical examination. Additional tests may be used when the diagnosis is uncertain or to assess complications.

  • Physical examination: A detailed scalp examination can identify painful nodules, pustules, abscesses, sinus tracts, scarring, and areas of hair loss.
  • Medical history: The healthcare provider may ask about the duration and recurrence of lesions, pain, discharge, hair loss, and previous treatments.
  • Skin biopsy: A biopsy may be performed when necessary to support the diagnosis and exclude other scalp conditions.
  • Microbial culture: Fluid or pus from an active lesion may be cultured when a secondary bacterial infection is suspected or antibiotic selection needs to be guided.
  • Imaging studies: Ultrasound or MRI may occasionally be used to evaluate extensive deep abscesses or sinus tracts.
  • Differential diagnosis: Conditions such as folliculitis, tinea capitis, acne keloidalis, hidradenitis suppurativa, and other scalp infections may need to be excluded.

What are the Treatment Options for Perifolliculitis Capitis Abscedens Et Suffodiens?

Treatment of perifolliculitis capitis abscedens et suffodiens focuses on reducing inflammation, controlling secondary infection, relieving symptoms, and preventing further scarring and hair loss. Treatment is individualized according to disease severity and may involve medical, procedural, or surgical approaches.

  • Antibiotics: Oral antibiotics such as tetracyclines or doxycycline may be used to control inflammation and treat suspected secondary bacterial infection.
  • Isotretinoin: Oral isotretinoin may be considered for moderate to severe disease to reduce follicular occlusion and inflammation under specialist supervision.
  • Corticosteroid injections: Intralesional corticosteroids may help reduce inflammation in selected painful or localized nodules.
  • Surgical drainage: Large, painful abscesses may require drainage to remove pus and relieve pressure.
  • Laser or light-based treatment: Selected laser-based approaches may be considered to reduce affected follicles and inflammation in recurrent disease.

Severe or persistent disease may require treatment by a dermatologist experienced in inflammatory and follicular scalp disorders. Early treatment is important because established scarring alopecia may result in permanent hair loss.
