Atypical fibroxanthoma of the scalp following hair transplantation in a 35-year-old male

SummaryAtypical fibroxanthoma (AFX) is an uncommon spindle cell neoplasm of the elderly. This case report presents an atypical case of AFX of the scalp 8 years after hair transplantation in a 35-year-old male patient. Possible synergistic effects of previous sun exposure radiation to the scalp, together with the thermal and radiation injury of carbon dioxide (CO2) laser, might explain the mechanisms of the development of AFX at such an early age.To the best of our knowledge, this case report is the first description in the medical literature of development of skin malignancy on a hair-transplanted scalp.
