The role of radiation therapy in the management of cutaneous malignancies. Part II: When is radiation therapy indicated?

J Am Acad Dermatol 2021 Jun 8. Epub 2021 Jun 8.

Departments of Dermatology and Head and Neck Surgery, The University of Texas MD Anderson Cancer, Houston, Texas, USA.

Radiation therapy may be performed for a variety of cutaneous malignancies depending on patient health status, tumor clinical and histologic features, patient preference, and resource availability. Dermatologists should be able to recognize the clinical scenarios in which radiation therapy is appropriate as this may reduce morbidity, decrease risk of disease recurrence, and improve quality of life. The second article in this 2-part continuing medical education series focuses on the most common indications for radiation therapy in the treatment of basal cell carcinoma, cutaneous squamous cell carcinoma, dermatofibrosarcoma protuberans, Merkel cell carcinoma, Kaposi sarcoma, angiosarcoma, cutaneous lymphoma, melanoma, undifferentiated pleomorphic sarcoma, and sebaceous carcinoma.

Raman spectroscopy based diagnosis of dermatofibrosarcoma protuberans: Case report.

Photodiagnosis Photodyn Ther 2021 May 25:102351. Epub 2021 May 25.

Department of Laser and Biotechnical Systems, Samara University, Samara, Russia. Electronic address:

Dermatofibrosarcoma protuberans is a rare disease and the rare occurrence of this pathology provokes insufficient oncological alertness among clinicians. A possible way to increase the accuracy of early diagnosis of rare skin neoplasms is "optical biopsy" using Raman spectroscopy tissue response. This case report of a 32-year-old woman with a dermatofibrosarcoma protuberans demonstrates that Raman spectroscopy based "optical biopsy" can help to diagnose rare tumors. Read More

Multicentric dermatofibrosarcoma protuberans in a child with severe combined immunodeficiency due to adenosine deaminase deficiency.

Pediatr Dermatol 2021 Apr 30. Epub 2021 Apr 30.

Departments of Paediatrics, Catholic Children´s Hospital Wilhelmstift, Hamburg, Germany.

We report the case of a 4-year-old boy, post-human stem cell transplantation for severe combined immunodeficiency (SCID) due to adenosine deaminase deficiency (ADA), who developed multiple dermatofibrosarcoma protuberans (DFSP). We hypothesize a role for chimerism leading to accumulation of toxic metabolites which can cause DNA strand breaks and inhibit lymphocyte activation. Patients with ADA-SCID should remain under lifelong dermatologic surveillance as DFSP lesions can be quite inconspicuous. Read More

What is the best surgical treatment for dermatofibrosarcoma protuberans?


Br J Dermatol 2021 04;184(4):e126-e147

Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing skin cancer that is primarily treated with surgery. Because this cancer can spread deep into the skin and surrounding tissue in an irregular way, it is notoriously difficult to ensure that it has been completely removed after conventional surgery and histological examination. Standard treatment in the UK is either wide local excision (WLE) or Mohs micrographic surgery (MMS). Read More

PDGFB RNA in situ hybridization for the diagnosis of dermatofibrosarcoma protuberans.

Mod Pathol 2021 Mar 24. Epub 2021 Mar 24.

Department of Pathology, Stanford University School of Medicine, Stanford, CA, USA.

Dermatofibrosarcoma protuberans (DFSP) is a spindle cell neoplasm of the skin and superficial soft tissue with a tendency for locally aggressive behavior; metastatic potential coincides with fibrosarcomatous transformation. The vast majority of DFSPs harbor the t(17;22) translocation resulting in a COL1A1-PDGFB fusion that drives autocrine growth stimulation via PDGFB overexpression. Here, we examined the utility of PDGFB RNA chromogenic in situ hybridization (CISH) for the diagnosis of DFSP. Read More
