Chinese Medical Journal 2014年第2期127卷 386-388页

dermatofibrosarcoma protuberans （DFSP） is a poorly differentiated interstitial tumor that originates from the dermis. It occurs predominantly in the 20-50-year- old males. DFSP generally presents as local pink plaques or nodules and subsequently develops into nodular masses accompanied by infiltrative growth to the surrounding tissue, including muscle and bone.

Case Reports in Clinical Medicine 2023年第6期12卷 196-201页

A 49-year-old woman was referred to the Department of Plastic and Breast Surgery under suspicion of breast cancer after a mammogram revealed a self-discovered tumor in the lower part of her left breast. Clinical examination, mammography, and histopathological examination revealed that the original tumor in the left breast was benign, and an incidental malignant tumor, a dermatofibrosarcoma protuberans (DFSP), was found in the contralateral breast. DFSP is a rare and highly malignant entity that is often silent and difficult to diagnose, making a biopsy essential. Surgical treatment must be aggressive due to the high risk of recurrence, which constitutes a technical challenge. The patient underwent surgery using an oncoplastic approach with a volume-reducing technique to achieve the best possible therapeutic and aesthetic results. Therapeutic breast reduction was performed on the right breast and the tumor was removed within the resected tissue. A contralateral symmetrizing mammoplasty was also performed simultaneously. The patient was discharged without major complications, and no recurrence of the tumor was seen during the 30-month follow-up period. The surgical approach included alternative solutions in addition to conventional lumpectomy or mastectomy. A multidisciplinary, open-minded, and creative approach resulted in a satisfying outcome for this patient.

dermatofibrosarcoma protuberans of the Neck: A Case Report

引用

International Journal of Otolaryngology and Head & Neck Surgery 2021年第2期10卷 85-91页

Background: dermatofibrosarcoma protuberans (DFSP) is rare soft tissue sarcoma but has a locally aggressive nature. Although most cases are of low grade and have a rare metastasis rate, all DFSP variants have a tendency to show local recurrence. Wide excision with negative margins is the treatment of choice. Aim: To report a case of DFSP who presented with an asymptomatic slow growing tumor similar to etiologies such as hypertrophic scars or other benign soft tissue tumors. Case Presentation: A 68-year-old male presented with a large soft tumor located at the left posterior neck. Local excision was done under the preoperative impression of a benign tumor such as lipoma or sebaceous cyst. However the diagnosis of DFSP was made upon histological examination and the patient underwent another surgery to achieve free resection margins under general anesthesia as well as adjuvant radiotherapy. Conclusion: DFSP is a malignant tumor that is diagnosed histopathologically. Due to the low incidence rate, slow-growing nature, and non-alarming initial presentation features, diagnostic delay or even misdiagnosis is not uncommon.
