Dermatofibrosarcoma protuberans: review of 20-years experience.

Introduction: Dermatofibrosarcoma protuberans (DFSP) is an uncommon soft tissue neoplasm with low-intermediate grade of malignancy. It is a locally aggressive tumour with a high recurrence rate. Surgical excision with adequate margins is the main treatment.

[Mammary hamartoma].

For many years, mammary hamartoma was considered to be an under-diagnosed disease. However, with the increasing use of diagnostic procedures in breast tumors (mammography, ultrasound, fine needle aspiration cytology and core needle biopsy), diagnosis of this entity has increased. Mammary hamartomas normally manifest as painless, mobile, palpable lumps without adherence to skin or muscle.
