An abscess is a localized collection of pus within tissue, caused by bacterial infection. It results from the body’s immune response to infection, leading to inflammation, tissue necrosis, and pus formation.
Incidence
- Common in skin and soft tissues, but can also occur in
internal organs.
- More frequent in diabetics, immunocompromised individuals, and
post-surgical cases.
- Can develop due to poor hygiene, trauma, or foreign bodies.
Definition
An abscess is a circumscribed
collection of pus caused by bacterial infection, leading to inflammation,
swelling, and pain.
Types of
Abscesses
1. Pyogenic
Abscess (Acute Abscess)
- Caused by bacterial infection (Staphylococcus, Streptococcus, E.
coli, etc.).
- Painful, red, swollen lump with pus.
- Fever, tenderness, and warmth present.
- Example: Skin boils, furuncles, carbuncles.
2. Cold Abscess
(Tuberculous Abscess)
- Caused by Mycobacterium tuberculosis.
- Slow-growing, painless swelling, often in lymph nodes or
bones.
- No redness or heat (hence called
"cold").
- Example: Tuberculous lymphadenitis (Scrofula), Pott’s abscess (spinal TB).
3. Pyaemic
Abscess (Septic Abscess)
- Multiple small abscesses formed due to bacteria spreading
via blood (septicemia).
- Caused by Staphylococcus, Streptococcus, or Gram-negative bacteria.
- Seen in infective endocarditis, osteomyelitis, or IV drug abuse.
- Can lead to multiple organ abscesses.
4. Internal
Organ Abscess
- Abscesses inside lungs, liver, brain, kidneys.
- Symptoms depend on the organ involved.
- Example: Liver abscess (Amoebic or Pyogenic), Brain
abscess.
Pathogenesis of
Abscess Formation (Mnemonic: PUS)
- P – Penetration of bacteria into tissue.
- U – Ulceration & breakdown of local tissue due to
bacterial toxins.
- S – Suppuration (pus formation) due to WBC response.
Clinical
Features (Mnemonic: PAINS)
- P – Pain (throbbing, localized).
- A – Abscess formation (swelling with pus).
- I – Inflammation (redness, warmth).
- N – Necrosis (tissue destruction in advanced cases).
- S – Systemic signs (fever, chills in severe infections).
Signs &
Symptoms
Superficial
Abscess
- Swelling with tenderness.
- Red, warm skin over the lump.
- Fluctuation test positive (fluid-filled swelling).
- Pus discharge when ruptured.
Deep Abscess
(Internal Organs)
- Fever with chills.
- Pain over the affected organ.
- Weakness, weight loss (if chronic).
- Jaundice in liver abscess, cough in lung abscess.
Laboratory
Investigations
- Complete Blood Count (CBC) – Shows high WBC count
(leukocytosis).
- CRP (C-Reactive Protein) – Elevated in infections.
- Blood Culture – Identifies bacteria in
systemic infections.
- Pus Culture & Sensitivity – Determines causative
organism & antibiotic choice.
- Ultrasound / CT Scan – Locates deep abscesses
(liver, brain, lungs).
- AFB Staining & TB PCR – Confirms tuberculous
abscess.
Management of
Abscesses
General
Measures (Mnemonic: DRAIN)
- D – Drainage of pus (Incision & Drainage - I&D).
- R – Rest & Warm compress to promote healing.
- A – Antibiotics for infection control.
- I – Immune support (nutrition, hydration).
- N – Necrotic tissue removal (debridement).
Allopathic
Treatment (Mnemonic: ABCDE)
- A – Antibiotics (Amoxicillin-Clavulanic Acid,
Cephalosporins).
- B – Broad-spectrum coverage for severe infections.
- C – Complete drainage to prevent recurrence.
- D – Debridement of necrotic tissue.
- E – Empirical therapy based on culture report.
Surgical
Treatment
- Incision & Drainage (I&D) – Standard treatment for
superficial abscesses.
- Aspiration – For deep abscesses
(liver, brain, lungs).
- Surgical excision – For chronic abscesses
or non-healing TB abscesses.
Homeopathic
Treatment
- Hepar Sulphuris
- Abscess with extreme tenderness and sensitivity.
- Pus is thick, yellow, and offensive.
- Pain worsens from cold air and slightest touch.
- Promotes suppuration (pus formation &
drainage).
- Best for abscesses in glands (lymph nodes,
tonsils, boils).
- Silicea
- For deep-seated abscesses that heal slowly.
- Pus is foul-smelling and persistent.
- Weak immunity, prone to recurrent abscesses.
- Chronic fistula, boils, and post-surgical wounds.
- Abscesses that do not heal completely.
- Calendula Officinalis
- Best as an antiseptic wound healer.
- Prevents secondary infections.
- Used for post-surgical wounds and open abscesses.
- Reduces inflammation and promotes rapid healing.
- External application speeds up healing
(Calendula lotion).
- Lachesis
- Abscesses with bluish or purplish discoloration.
- Septicemia, blood poisoning from infected wounds.
- Intolerance to tight clothing.
- Symptoms worse after sleep.
- Prevents the spread of septic infections.
- Mercurius Solubilis
- Painful, pus-filled abscess with excessive
salivation.
- Pus has a metallic, offensive smell.
- Worse at night, increased sweating.
- Tongue has a thick, dirty coating (common in
dental abscesses).
- Useful for abscesses in throat, gums, and oral
infections.
Mnemonic for
Homeopathic Treatment (SHaLL-M)
- S – Silicea (Slow-healing abscesses).
- H – Hepar Sulph (Painful, sensitive abscesses).
- L – Lachesis (Septic, bluish-purple abscesses).
- L – Calendula (External healing, prevents infection).
- M – Mercurius Sol (Pus with foul breath, oral abscesses).
