Background:
Dermatofibrosarcoma protuberans (DFSP) is a low-grade malignant soft tissue tumor of subcutaneous tissues that has a propensity for local recurrence; however, it seldom metastasizes. Most lesions occur over the trunk or proximal extremities, and there is slight male preponderance. DFSP is rare on the head and neck. Less than 5% tumors are located on the scalp.
Objective:
To describe a case of giant fibrosarcoma arising in DFSP on the scalp during pregnancy.
Method:
In our patient, the tumor was on scalp and measured 15 x 11 x 7 cm. The recurrent tumor that developed in the same region was measured 33 x 30 x 15 cm. Histopathologic examination of this mass revealed fibrosarcoma. The mass was excised from the subperiosteal plane with a 3-cm free margin. Because of the high possibility of recurrence, the defect site was reconstructed with a split-thickness skin graft.
Results:
After 1 year of follow-up, no recurrence or metastasis was detected.
Conclusion:
We present a unique case in which the person has a giant fibrosarcoma on her scalp arising from DFSP with fibrosarcomatous change during pregnancy.
