Summary

Leprosy can mimic sporotrichosis, presenting as skin lesions and nerve abscesses during treatment. Early diagnosis is crucial to prevent nerve damage using corticosteroids.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Neurology

Background:

  • Leprosy (Hansen's disease) is a chronic infectious disease primarily affecting the skin and peripheral nerves.
  • Sporotrichoid spread describes infections that ascend along lymphatic channels, often mimicking sporotrichosis.
  • Understanding atypical presentations of leprosy is vital for timely diagnosis and management.

Observation:

  • Two adult leprosy patients presented with clinical signs resembling sporotrichosis.
  • One patient had skin and nerve involvement, while the other had isolated nerve disease.
  • Both exhibited upgrading reactions with plaque erosion, scarring, and acute nerve abscesses during anti-leprosy therapy.

Findings:

  • Histopathology confirmed leprosy in both cases.
  • The clinical presentation mimicked sporotrichoid infection due to reactive inflammation and abscess formation along nerves.
  • Leprosy reactions can manifest with features suggestive of other infections.

Implications:

  • Leprosy should be considered in the differential diagnosis of sporotrichoid infections.
  • Prompt diagnosis and corticosteroid treatment are essential to prevent irreversible nerve destruction in leprosy reactions.
  • Recognizing this sporotrichoid pattern aids in early intervention and improved patient outcomes.
