Summary

Lesions on the scalp are frequently encountered in clinical practice. Commonly diagnosed lesions include epidermal inclusion cysts (EICs), dermoid cysts and lipomas. Dermatofibrosarcoma protuberans (DFSP) is a low-grade malignant skin tumour occurring mostly in the extremities. However, its occurrence on the scalp is unusual, with an incidence of <5%. This lesion is rarely known to undergo fibrosarcomatous transformation. We present two such rare cases of DFSP of the scalp, with fibrosarcomatous transformation, masquerading clinically as EIC.
