A man in his 20s presented with a large, verrucous plaque on his right calf (Figure, A). The lesion initially appeared as a small, bluish plaque at a young age and had gradually increased in size with subsequent development of wartlike features. Aside from minor local pain and pruritus, the patient reported history of recurrent infections as well as oozing and bleeding after minimal trauma. Physical examination revealed soft, compressible nodules overlying a friable verrucous plaque in a linear distribution involving the length of the right calf with minimal tenderness on palpation. No other lesions were found on the body. A deep punch biopsy specimen was obtained and sent for histopathological examination (Figure, B and C).
