Non-melanoma skin cancer is the most common type of neoplasia. Basal cell carcinoma is the most common cancer of them, the incidence of which is steadily increasing, implying an important public and financial health issue. The authors present the case of a patient with an extensive basal cell carcinoma affecting part of the external auditory canal and auricular concha, treated with a combination of surgical techniques: flap-plasty associated with second intention closure of the external auditory canal. Due to the excellent aesthetic and functional outcomes, this technique should be considered as a therapeutic option for auricular lesions.

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.
