Objective:

To report a case of digital actinomycosis in a young patient and highlight the diagnostic process.

Key Findings:
  • The lesion was firm, nontender, and showed no skin discoloration or lymphadenopathy.
  • Histopathology confirmed actinomycosis through the presence of sulfur granules.
  • The patient recovered without recurrence after surgical excision.
Interpretation:

Actinomycosis should be considered in the differential diagnosis of chronic digital masses, especially with lytic bone changes.

Limitations:
  • Culture confirmation of Actinomyces can be challenging due to slow growth and contamination risk.
  • The case is based on a single patient report, limiting generalizability.
Conclusion:

Early recognition of actinomycosis can prevent misdiagnosis and guide appropriate treatment, emphasizing the role of histopathology in diagnosis.
