INTRODUCTION: Dermatofibrosarcoma protuberans (DFSP) is a local aggressive sarcoma that presents 60% of recurrences. Rarely it presents lung metastasis too.
METHODS: 41 years old man presented a soft tumor in his right hallux for two years. Histopathology has shown spindle-shaped cells arranged in a storiform manner, and immunohistochemistry was CD34 positive.
DISCUSSION: The literature describes some clinical types of DFSP. The most common are: confluent nodules forming a plaque, sometimes similar to keloids, tumoral lesions, and atrophic plaques.
CONCLUSION: DFSP cases simulating a subcutaneous cyst have been described in the literature; nevertheless, it is an unusual presentation of this tumor.
