Area of Science:

  • Dermatology
  • Pathology

Background:

  • Cutaneous reactions to plant materials can present with diverse clinical manifestations.
  • Cholla cactus (Cylindropuntia spp.) spines are known to cause foreign body reactions and granulomas.

Observation:

  • A 45-year-old woman presented with a 2-week history of painful, erythematous papules on her right fingertip.
  • The lesions appeared 3 weeks after contact with cholla cactus in Arizona.

Findings:

  • Initial treatment with clobetasol propionate ointment provided partial improvement.
  • Punch biopsy confirmed the diagnosis of cactus spine granuloma, leading to complete resolution of the lesions.

Implications:

  • This case underscores the importance of considering phytogenous granulomas in the differential diagnosis of persistent fingertip lesions.
