    Sclerosing Dermatofibrosarcoma Protuberans Shows Significant Overlap With Sclerotic Fibroma in Both Routine and Immunohistochemical Analysis: A Potential Diagnostic Pitfall.
    Am J Dermatopathol 2017 Feb;39(2):83-88
    Departments of *Dermatology, and †Pathology, University of California San Francisco, San Francisco, CA.
    Dermatofibrosarcoma protuberans (DFSP) is an uncommon, low-to-intermediate grade sarcoma with several histologic variants, including pigmented (Bednar tumor), sclerosing, myxoid, atrophic, and DFSP with fibrosarcomatous changes. Two patterns of sclerosis in DFSP can be observed, a sclerotic fibroma-like pattern and a morphea/lichen sclerosus-like pattern. Partial biopsies of sclerosing DFSPs with the sclerotic fibroma pattern can be misdiagnosed as sclerotic fibroma or other benign sclerosing tumors (eg, perineurioma, dermatofibroma). Read More
