Wide local excision, Mohs micrographic surgery, and reconstructive options for treatment of dermatofibrosarcoma protuberans of the breast: A retrospective case series from Mayo Clinic

Dermatofibrosarcoma protuberans of the breast in pregnancy

Dermatofibrosarcoma Protuberans (DFSP) is a rare, locally aggressive fibroblastic mesenchymal neoplasm, typically derived from the dermis, with the intramammary subtype being seen infrequently. We present a case of a 40-year-old woman whom was diagnosed with an intramammary DFSP during pregnancy, whom underwent successful surgical management during her second trimester. Our case demonstrates the importance of increased clinical awareness in the diagnosis and treatment of breast DFSP with careful multidisciplinary consideration.

Dermatofibrosarcoma Protuberans (DFSP) with Fibrosarcomatous Changes in a Patient with Crohn's Disease Treated with Anti-TNF (Adalimumab)

Dermatofibrosarcoma protuberans (DFSP) is a low-to-intermediate grade sarcoma with a reported incidence of 4.1 per million person-years. Despite its local invasiveness, it rarely metastasizes (5% of cases). Fibrosarcomatous change in DFSP is a form of tumor progression that carries an increased risk of metastases. We reported a case of 45-year-old patient treated with adalimumab lasting 7 years for Crohn's disease who developed dermatofibrosarcoma protuberans with fibromatous changes. Adalimumab therapy was stopped before surgery, and ustekinumab was introduced 6 months after.
