Intracranial recurrence of the scalp dermatofibrosarcoma.

We report a case of recurrent scalp dermatofibrosarcoma in a 30-year-old woman who underwent surgical intervention on three separate occasions during a 60-month period, and who received post-operative radiotherapy. A small, hard, elastic mass on the right parieto-occipital scalp was initially treated by simple resection in another clinic. Despite surgical intervention and radiotherapy, a recurrent tumor associated with infiltration to the calvarium was detected. The patient was then referred to our institution and a wide resection performed. Two years later, however, the patient was readmitted to our institution as a result of tumor recurrence with intracranial involvement. Scalp dermatofibrosarcoma is an uncommon but aggressive scalp tumor; therefore, wide local excision with good margins is essential to decrease the risk of regional recurrence. Close surveillance in these cases is necessary due to late tumor recurrences.
