Actinomycetoma caused by Nocardia brasiliensis

Last edited: 4/15/2026

Overview

Actinomycetoma caused by Nocardia brasiliensis is a chronic granulomatous infection characterized by localized abscesses, draining sinuses, and bone involvement, typically affecting the skin and subcutaneous tissues 1.

Diagnosis

  • Clinical presentation includes chronic skin lesions, draining sinuses, and systemic symptoms like fever 1.
  • Microbiological confirmation through culture of the organism from pus or tissue samples is essential 1.
  • Histopathological examination showing granulomas with filamentous bacteria supports the diagnosis 1.
  • Polymerase chain reaction (PCR) may aid in rapid identification 1.

    • Management

  • First-line treatment involves prolonged antimicrobial therapy, typically with sulfonamides such as sulfadiazine, often combined with trimethoprim 1.
  • Adjunctive surgical interventions like debridement or resection may be necessary for extensive disease or abscesses 1.
  • Duration of therapy is generally prolonged, often lasting several months to years, depending on the response and extent of infection 1.

    • Special Populations

  • No specific guidelines provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.

    • Key Recommendations

  • Confirm diagnosis through culture and histopathological examination of affected tissue samples (Evidence: Moderate 1).
  • Initiate treatment with sulfonamides such as sulfadiazine, potentially combined with trimethoprim, for prolonged periods (Evidence: Moderate 1).
  • Consider surgical debridement for patients with extensive or refractory disease (Evidence: Expert opinion 1).
