Overview

Overview

Phlegmon is a spreading diffuse inflammatory process with formation of suppurative/purulent exudate or pus.

Pathophysiology

Factors affecting the development of phlegmons are virulence of bacteria and human’s immunity strength defenses.

Causes

Phlegmon is commonly caused by bacteriastaphylococci, streptococci, pneumococci, spore and non-spore forming anaerobes, etc.

Diagnosis

History and Symptoms

Systemic features of infection like increased body temperature (up to 38-40°C), general fatigue, chills, sweatings, headache, and loss of appetite may be present.

Physical Examination

Inflammatory signs – dolor (localized pain), calor (increase local tissue temperature), rubor (skin redness/hyperemia), tumor (either clear or non-clear bordered tissue swelling), functio laesa (diminish affected function) may be present. Severity of patient condition with phlegmons is directly proportional to the degree of intoxication level i.e the severe the condition, the higher degree of intoxication level.

Laboratory Findings

The main goal of treatment is to remove the cause of phlegmonous process in order to achieve effective treatment and prevention of recurrence. If patients condition is mild and the signs of inflammatory process is presence without signs of infiltrates, then conservative treatment with antibiotics is sufficient.

Classification

By Clinical Course

  1. Acute
  2. Subacute

By Severity of Condition

  1. Mild
  2. Average
  3. Severe (with spreading to other location(s))

By Location

  1. Superficial
  • Cutaneous
  • Subcutaneous
  • Interstitial tissue
  • Intramuscular
  1. Deep
  • Mediastinal
  • Retroperitoneal

By Etiology

  1. Single
  2. Mixed (eg:spore and non-spore forming anaerobes)

By Pathogenesis

  1. Per continuitatem (through neighbouring tissues)
  2. Hematogenous (through non-valvular veins like venous plexus of face eg: v. pterygoideus plexus → inflamation of veins (phlebitis) → thrombus formation in veins → embolization of thrombus into sinus venousus systems)
  3. Odontogenous

By Exudative Character

  1. Purulent phlegmon
  2. Purulent-hemorrhagic phlegmon
  3. Putrefactive phlegmon

By Presence of Complications

  1. With complications (disturbance of mastication, ingestion, speech, cardiovascular and respiratory system, peritonitis, lymphadenitis, loss of conscious if very severe, etc)
  2. Without complication
