Carbuncle
Definition:
Carbuncle is an infective gangrene of the subcutaneous tissue Staphylococcus aureus Bacteria are mostly responsible for this. (1)
Carbuncle has a few synonyms depending on the context:
Formal Synonyms (Medicine):
- Furuncle cluster: This medical term describes the nature of a carbuncle, which is a cluster of interconnected furuncles (boils).
Informal Synonyms:
- Multiple boil: This is a simple and clear term for someone without medical expertise.
- Cluster of boils: Similar to "multiple boil," but emphasizes the grouping.
Choosing the Right Synonym:
- Medical Context: Use "furuncle cluster" for precise communication.
- Informal Context: "Multiple boil" or "cluster of boils" are easily understandable by most people.
Additionally:
- You could use descriptive phrases like "a large, inflamed infection under the skin that looks like multiple boils connected together" for a more detailed explanation.
Remember: The best synonym depends on the level of formality and the audience’s medical knowledge.

Overview
Overview of Carbuncle:
- A carbuncle is a red, swollen, and painful cluster of boils and they connectes to each other under the skin.
- A carbuncle is most likely to occur on a hairy area of the body such as the back or nape of the neck, But a carbuncle also can develop in other areas of the body such as the buttocks, thighs, groin, and armpits.
- Staphylococcus aureus bacteria are cause of Most carbuncles , which inhabit the skin surface, throat, and nasal passages.
- The infection can spread to other parts of the person’s body or to other people through skin-to-skin contact or the sharing of personal items So, it’s important to practice appropriate self-care measures, like keeping the area clean and covered, until the carbuncle drains and heals. (2)
Epidemiology
Epidemiology:
While there isn’t readily available, specific data on the incidence of carbuncles in India, a few sources provide insights:
Carbuncle: A challenging infective lesion (ResearchGate, 2023):
- This research article mentions that "The exact incidence of carbuncle is variable. They are more commonly seen in males, especially in whom predisposing conditions such as compromised skin barrier due to eczema, diabetes, alcohol abuse, malnutrition, immunocompromised status, etc. coexist." While it doesn’t give specific numbers for India, it highlights the common predisposing factors that might contribute to cases in the country. [9]
Risk factors for recurrent furunculosis in patients with a single furuncle (International Journal of Dermatology, 2009):
This study investigated risk factors for recurrent furunculosis (which can include carbuncles) but doesn’t provide India-specific data. However, it does note that furunculosis is a common problem in tropical climates like India’s. [10]
A rare presentation of carbuncle in an infant (Indian Journal of Dermatology, 2014):
- This case report discusses a rare occurrence of a carbuncle in an infant, suggesting that while not common, carbuncles can affect various age groups in India. [11]
Important Note: These references highlight the challenges of finding comprehensive epidemiological data for specific skin conditions like carbuncles in India. While not providing exact numbers, they offer some context and potential areas for further research.
Causes
Causes of Carbuncle:
1. Staphylococcus Aureus
- While other bacteria are sometimes responsible,Staphylococcus aureus Causes the vast majority of carbuncles.
- Staph. is a very common bacteria found on the skin, inside of the nose, and in the genital area.
- The problem develops when the bacterium enters the skin through a broken area, There doesn’t have to be a large injury for the infection to take hold.
- In some cases, it could be a simple scratch, scrape, insect bite, or even a microtear.
- Friction also plays a role in carbuncle development, as it can lead to irritation and inflammation of the hair follicle that allows the infection to more easily take hold.
2. MRSA :
- Methicillin-resistant Staphylococcus aureus (MRSA) is becoming a fairly common cause of carbuncles, especially recurrent ones.
- These infections most commonly occur in the groin, buttocks, and upper-thigh region. (3)
Types
Types:
While the classification of carbuncles is not always explicitly detailed in the literature, they can be broadly categorized based on location and causative organism:
Location:
Neck Carbuncle: This type occurs on the back of the neck and can be particularly dangerous due to its proximity to vital structures.[12]
Facial Carbuncle: These carbuncles develop on the face and can be associated with significant cosmetic concerns.[13]
Other Locations: Carbuncles can occur on any part of the body, including the back, buttocks, and thighs. [14]
Causative Organism:
Staphylococcal Carbuncle: Most carbuncles are caused by Staphylococcus aureus bacteria.[15]
Other Bacterial Carbuncles: Occasionally, carbuncles can be caused by other bacteria, such as Streptococcus pyogenes.[16]
It’s important to note that the classification of carbuncles is not always strict, and a combination of factors may be present in a single case. The specific treatment approach will depend on the location, severity, and the patient’s underlying health conditions.
Risk Factors
Risk factor of Carbuncle:
Carbuncles can affect anyone at any age and are most common in men who are middle-age or older.
Obesity:
- Being Heavy weight increases susceptibility to skin infections.
- This may be because bacteria thrive in moist environments such as skin folds, or that being heavy weight makes it harder to fight infection.
- The risk is highest in those with a BMI over 30.5
Diabetes:
- Carbuncles are especially common in those with uncontrolled diabetes.
Chronic skin conditions:
- This includes common conditions such as acne, folliculitis, eczema, and other types of dermatitis.
Become Immunocompromised:
- Those with chronic infections, HIV, cancer, and other conditions that weaken the immune system are at greater risk for developing carbuncles.
- This is because the body has a harder time fighting off infection, allowing bacteria to rapidly grow unchecked.
Certain medications:
- Medications that weaken the immune system also prevent body from fighting carbuncle-causing infections efficiently.
- Examples include long-term oral steroids and chemotherapy.
Having multiple or recurrent boils:
- Certain people are more susceptible to get infected from staph.
- Those prone to recurrent cases are likely to develop more serious abscesses like carbuncles.
Other health conditions:
- Carbuncles are also more common in those with health conditions like heart failure, liver disease, and kidney disease. (3)
Pathogenesis
Pathogenesis:
The pathogenesis of a carbuncle involves a complex interplay of bacterial invasion, host immune response, and tissue destruction. Here’s a breakdown with references:
Bacterial Invasion:
- Most commonly caused by Staphylococcus aureus.
- Bacteria enter through hair follicles or breaks in the skin.
- Colonization and proliferation within the hair follicle lead to inflammation. [12]
Inflammatory Response:
- The body’s immune system responds to the bacterial infection.
- Neutrophils and other immune cells infiltrate the area.
- Release of inflammatory mediators leads to swelling, redness, and pain. [13]
Abscess Formation:
- Infection spreads to deeper tissues, forming multiple interconnected abscesses.
- Abscesses contain pus, a mixture of dead bacteria, immune cells, and tissue debris.
- Pus may drain through multiple openings in the skin. [14]
Tissue Necrosis:
- Bacteria release toxins that cause tissue damage and necrosis (cell death).
- This leads to the formation of a central core of necrotic tissue within the carbuncle. [15]
Systemic Spread (Rare):
- In severe cases, bacteria can spread to the bloodstream, causing sepsis.
- This can lead to fever, chills, and other systemic symptoms. [16]
Pathophysiology
Pathophysiology of Carbuncle:
- The initial lesion is similar to a boil in the form of hair follicle infection with peri folliculitis.
- Since majority of patients are diabetics, infection takes a virulent course and results in necrosis of subcutaneous fat which gives rise to multiple abscesses.
- These abscesses are intercommunicating, and they open to the exterior with multiple openings which can called sieve-like openings.
- This appearance described as cribriform appearance which is pathognomonic of carbuncle. (1)
Clinical Features
Clinical Features:
A carbuncle is a cluster of boils (furuncles) that form a connected area of infection under the skin.
Clinical features:
- Red, painful, and swollen lump under the skin
- May grow rapidly over a few days
- Pus-filled heads may form on the surface, which may drain
- Fever, chills, and fatigue [13]
Please note: The clinical features described above are a general overview. The specific presentation of a carbuncle can vary depending on the individual and the location of the infection. Always consult a healthcare professional for diagnosis and treatment.
Sign & Symptoms
Sign & Symptoms of Carbuncle:
- Severe pain and swelling in the nape of the neck.
- Constitutional symptoms such as fever with chills and rigors are severe.
- Surface is red, angry looking like RED-HOT COAL.
- Surrounding area indurated.
- Later, skin on the centre of carbuncle softens and peripheral satellite vesicles appear, which rupture discharging pus and giving rise to a cribriform appearance.
- The end result is development of a large crateriform ulcer with central slough. (1)
Clinical Examination
Investigation of Carbuncle:
- Urine sugar and urine ketone bodies.
- Blood sugar.
- Discharge for C/S. (4)
Diagnosis
Diagnosis of Carbuncle:
- Clinical diagnosis should confirmed after culturing the organism from the exudates.
- Phage typing employes for identifying the strains in epidemics and tracing the Carriers. (7)
Differential Diagnosis
Differential Diagnosis of Carbuncle:
Furuncle (boil):
- A single, inflamed hair follicle.
Hidradenitis suppurativa:
- A chronic inflammatory skin condition that causes abscesses and scarring in the armpits, groin, and other areas.
Epidermal inclusion cyst:
- A benign, closed sac under the skin that contains keratin.
Abscess:
- A collection of pus under the skin.
Deep fungal infection:
- A fungal infection that extends into the deeper layers of the skin and subcutaneous tissue.[13]
Complications
Complications of Carbuncle:
Cellulitis:
- A spreading bacterial infection of the skin and subcutaneous tissues.
Abscess formation:
- A collection of pus that may require drainage.
Lymphangitis:
- Inflammation of the lymphatic vessels.
Bacteremia:
- Bacteria in the bloodstream, which can lead to sepsis.
Scarring:
- Especially with large or deep carbuncles.[13]
Investigations
Investigations of Carbuncle:
Culture and sensitivity of pus:
- To identify the causative organism and determine appropriate antibiotic therapy.
Blood cultures:
- In cases of systemic symptoms or suspected bacteremia.
Complete blood count (CBC):
- To assess for signs of infection and inflammation.
Blood glucose:
- To screen for diabetes, a risk factor for carbuncles.
Imaging studies (ultrasound, CT scan, MRI):
- Rarely needed, but may be helpful in assessing the extent of infection or ruling out other conditions.[13]
Treatment
Treatment of Carbuncle:
- Diabetes control, preferably with injectable insulin.
- Appropriate parenteral antibiotics are given till complete resolution occurs.
- Most strains of Staphylococcal aureus are sensitive to cloxacillin, flucloxacillin, erythromycin and some of the cephalosporins.
- However, methicillin-resistant Staphylococcal aureus (MRSA) bacteria are resistant to the drugs mentioned above.
- They are sensitive only to expensive drug vancomycin which must be given intravenously.
- Improve general health of the patient.
- If carbuncle does not show any softening or if it shows evidence of healing, it is not incised.
- It can be left open to the exterior or saline dressings may be applied to reduce oedema.
- Complete resolution may take place within 10-15 days.
- Surgery is required when there is pus.
- Cruciate incision is preferred because of multiple abscesses and extensive subcutaneous necrosis.
- Edges of the skin flap are excised, pus is drained, loculi are broken down, slough is excised, and cavity is irrigated with antiseptic agents.
- Like pyogenic abscess, wound heals with granulation tissue from the depth excision of carbuncle. (1)
Prevention
Prevention of Carbuncle:
Follow this prevention tips:
