A Diabetic Woman with a Left-Thumb Lesion After Cactus- Thorn Trauma

We report the case of a woman with diabetes mellitus who developed a skin and soft tissue infection of the left thumb following trauma caused by a cactus thorn. Despite initial antibiotic therapy, no clinical improvement was observed. Broad-spectrum antimicrobial therapy was subsequently initiated, and wound cultures were obtained. Candida tropicalis was identified as the causative pathogen. Targeted antifungal therapy led to clinical improvement. The patient required repeated surgical debridement, and a skin graft was applied during the healing process. The patient ultimately recovered without recurrence.
