Pigmented dermatofibrosarcoma protuberans

Introduction. Dermatofibrosarcoma protuberans (DFSP) is a relatively rare distinct dermal and subcutaneous neoplasm, which is generally regarded as a low-grade sarcoma ().Although DFSP is characterized clinically as locally aggressive with a high rate of local recurrence, distant metastases are rare A case of congenital pigmented dermatofibrosarcoma protuberans (Bednar tumor) in a patient with Fanconi anemia The present paper reports a 67-year-old male with pigmented dermatofibrosarcoma protuberans (Bednar tumor) on his right shoulder.

  2. Dermatofibrosarcoma protuberans (DFSP) is a very rare type of skin cancer that begins in connective tissue cells in the middle layer of your skin (dermis). Dermatofibrosarcoma protuberans may at first appear as a bruise or scar. As it grows, lumps of tissue (protuberans) may form near the surface of the skin
  3. Dermatofibrosarcoma protuberans (DFSP) is a relatively rare low-grade sarcoma that occasionally exhibits melanin-containing spindle cells within the tumor. Fibrosarcomatous DFSP (FS-DFSP) is a variant that is characterized by areas which are histopathologically indistinguishable from fibrosarcoma. In the present study, we describe a case of fibrosarcomatous pigmented DFSP and review the.

Dermatofibrosarcoma Protuberans - Causes, Staging, Treatmen

Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing, painless tumor of the skin that frequently arises on the trunk. 1 It typically arises in youthful individuals in individuals ages 20-40 years. It is believed that the cell of origin in DFSP is a dermal stem cell or an undifferentiated mesenchymal cell with fibroblastic, muscular, and neurologic features. 2 The tumor originates.

Synonyms: DFSP, Giant cell fibroblastoma, Familial dermatofibrosarcoma protuberans (subtype), Metastatic dermatofibrosarcoma protuberans (subtype) Desmoplastic small round cell tumor. Bednar tumour is a pigmented variant of dermatofibrosarcoma protuberans (DFSP), constituting 1 to 5% of all DFSPs, which in turn, represent 0.1% of skin malignancies. It is histopathologically characterised by scattered melanosome-containing dendritic cells within an otherwise typical DFSP

We encountered a rare case of Bednar tumor with multiple different distant metastases. A 51-year-old man, who had had a history of mass resection in his left shoulder 4 years previously, was referred to. INTRODUCTION. Bednar tumors are rare; they were described by Bednar in 1957. 1 They are considered to be a pigmented variant of dermatofibrosarcoma protuberans (DFSP), and differ from DFSP by the presence, in the histopathologic exam, of dendritic cells containing melanin, dispersed amidst the fusiform cells characteristic of DFSP. They involve individuals predominantly in the third and fourth. On the basis of above analysis, a diagnosis of subcutaneous dermatofibrosarcoma protuberans was made.

Dermatofibrosarcoma protuberans (DFSP) is a slow growing, low- to intermediate-grade dermal soft-tissue tumor. It has a high local recurrence rate but low metastatic potential. It is characterized by a uniform spindle cell arrangement, classically with a storiform pattern and CD34 immunoreactivity. The histomorphology and immunophenotype overlap with a broad range of other neoplasms completely as dermatofibrosarcoma protuberans, of either classical or pigmented types. The cytoge-netic abnormalities and molecular events in GCF are identical to those in DFS [42, 43]. This tumor is therefore currently considered to be a (juvenile) variant of DFS. FIG. 3 Myxoid dermatofibrosarcoma. Other part Dermatofibrosarcoma Protuberans (DFSP) is a rare skin tumor, characterized by frequent local recurrence but is seldom metastatic.
