2024年4月18日 · Dermatofibrosarcoma protuberans (DFSP) is an uncommon soft tissue sarcoma primarily found on the trunk and proximal extremities that typically appears as a slowly progressing, firm, violet-red, or blue plaque. Because DFSP is a slow-growing tumor, the diagnosis is often delayed for months to years.

2022年8月29日 · Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing skin cancer. It may start in a scar, tattoo or burn. Mohs surgery can remove the tumor.

Dermatofibrosarcoma protuberans (DFSP) [2] is a rare locally aggressive malignant cutaneous soft-tissue sarcoma. DFSP develops in the connective tissue cells in the middle layer of the skin (dermis). [3] Estimates of the overall occurrence of DFSP in the United States are 0.8 to 4.5 cases per million persons per year.

Dermatofibrosarcoma protuberans usually presents as a painless thickened area of skin (plaque) and/or nodule that feels rubbery or firm to touch and is fixed to the underlying skin. It may be red-brown or skin coloured. It usually grows very slowly over months to years.

2023年6月22日 · Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive, superficial mesenchymal neoplasm with fibroblastic differentiation

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.

When dermatofibrosarcoma protuberans (DFSP) first appears on the skin, a person may notice: DFSP often looks like this harmless and common skin growth, a dermatofibroma. In children, this skin cancer tends to resemble a birthmark. The first sign of this skin cancer may be reddish brown or pink patch of raised skin that looks like a scar.
