Summary

Primary cutaneous Nocardia asteroides mycetoma, a rare skin infection, occurred in an immunocompetent patient. Successful treatment was achieved with trimethoprim-sulfamethoxazole, highlighting the need for clinical suspicion and laboratory awareness.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Microbiology

Background:

  • Primary cutaneous Nocardia asteroides infections are uncommon, typically affecting immunocompromised individuals.
  • Nocardia asteroides can cause mycetoma, a chronic infectious disease affecting the skin and subcutaneous tissues.

Observation:

  • A case of primary cutaneous Nocardia asteroides mycetoma was observed in an immunocompetent patient.
  • The patient presented with a skin infection characteristic of mycetoma.

Findings:

  • The infection was successfully treated with trimethoprim-sulfamethoxazole.
  • Nocardia asteroides mycetoma can occur in immunocompetent individuals, challenging previous assumptions.

Implications:

Related Experiment Videos

  • Clinicians should consider Nocardia asteroides in the differential diagnosis of cutaneous mycetoma, even in immunocompetent patients.
  • Alerting microbiology laboratories is crucial due to the prolonged culture incubation and specific tests required for Nocardia identification.
  • This case expands the known clinical spectrum of Nocardia asteroides infections.
