Abstract
- Dermatofibroma is a common benign fibrohistiocytic tumor. It can occur anywhere on the body surface, but it has a propensity for the extremities. However, dermatofibroma may show a wide variety of clinicopathologic variants and so it is often misdiagnosed. Our case was a 13-year-old male who presented with a 1-year history of a solitary skin-colored hyperkeratotic nodule on the right sole. The nodule had recurred after topical therapy for viral wart. Histopathologic examination of the patient's lesion revealed a poorly circumscribed nodular tumor composed of collagen bundles, fibroblasts and histocytes, which was all consistent with plantar dermatofibroma.
