Image of the Week: Did a cactus barb cause this painful growth?


  • Slide

A pregnant woman presents with this lesion at a site where a barb from a cactus became embedded 3 weeks earlier. This patient’s recent injury is suggestive of sporotrichosis—an infection caused by the fungus Sporothrix schenckii, which is commonly present in soil and classically associated with rose thorns. However, the patient’s pregnancy and the lesion’s size call to mind a pyogenic granuloma—a benign vascular tumor of the skin or mucous membranes that is sometimes triggered by injury. Learn more about this case and join the conversation on Figure 1.
