Dermatofibrosarcoma protuberans - recurrence

Discussion:

The recent case was previously diagnosed as dermatofibrosarcoma protuberans after left upper thigh mass excision two years ago as followed:

Microscopic evaluation:

Ill-defined dermal and subcutaneous neoplasm with interfacing fascicles and few storiform growth patterns. Individual monomorphic tumoral cells characterized by a fusiform elongated nucleus with pinpoint ended, fibrillar cytoplasm with indistinct cell borders. Mitotic activity is rare. A few multinucleated giant cells seen. In some area of stroma shows myxoid changes, epidermal appendage and fat cells entrapped by the tumor.

The most common location of dermatofibrosarcoma protuberans tumor is the trunk wall followed by the proximal extremities. The mass has a high local recurrence rate, therefore, multiple follow up is usually indicated.
