When a wound heals, especially an infected one, new granulation tissue forms. If this is so excessive as to make an obvious lump, you can mistake it a tumour. A pyogenic granuloma can occur anywhere, but is commonest on the face, fingers, or toes, as a soft or moderately firm, dull red, 1 cm lump, covered with atrophic epidermis or crusts, and which bleeds easily. This trivial lesion can be misdiagnosed and thought to be a sarcoma, when all that is needed is simple excision and curettage. An antibiotic is only needed if there are signs of spreading infection (very unusual).
