Dermatofibrosarcoma protuberans is an uncommon cancer in which tumors arise in the deeper layers of skin. The tumor usually starts as a small, firm patch of skin; it may be purplish, reddish, or flesh-colored. It is commonly found on the torso, usually in the shoulder and chest area Dermatofibrosarcoma protuberans (DFSP) is a rare fibroblastic skin tumor of intermediate malignancy. Its pathogenesis has not yet been fully clarified. Recent basic genetic research has shown chromosomal translocations, generally termed ring chromosomes, in DFSP. These arise from a fusion of chrom Dermatofibrosarcoma protuberans (DFSP) is a rare monoclonal cutaneous soft tissue sarcoma that was first described by Taylor in 1890. 1 Chang et al., 2 reporting on 60 patients with DFSP who were treated at the University of Illinois-Chicago (Chicago, IL) between 1968 and 2001, estimated that approximately 100 patients with soft tissue sarcoma (any type) were treated each year at their. Dermatofibrosarcoma protuberans treated with wide local excision has a recurrence rate of about 7.3% compared to a recurrence rate of about 1% when treated with MMS. If feasible, modified wide local excision with horizontal sectioning, as opposed to the usual histologic vertical processing ('bread-loafing), and detailed mapping can be performed to decrease the likelihood of local recurrence Dermatofibrosarcoma protuberans (DFSP) is a low-grade malignant tumor arising from dermal and subcutaneous tissues and is the most common cutaneous sarcoma (although overall still quite rare).It is most commonly found at the trunk and proximal extremities 6.. Its behavior is notable for a high reported rate of local recurrence, although outcomes overall are favorable

Dermatofibrosarcoma Protuberans: Diagnosis, Treatment

If dermatofibrosarcoma protuberans spread to other parts of the body, the signs and symptoms vary depending on the size of the metastatic tumor and which organ it affects. Regular physical examinations can help detect recurrence of the tumor in the original location or signs that it has spread to other parts of the body. The physical examination includes a skin examination to look for any. Dermatofibrosarcoma protuberans. As dermatofibrosarcoma protuberans grows, lumps of tissue (protuberans) may form near the surface of the skin Keywords: Dermatofibrosarcoma protuberans, DFSP, Cutaneous lesions, Mesenchymal tumor, Wallace rule of 9s Introduction Dermatofibrosarcoma protuberans (DFSP) is a rare low-grade soft tissue sarcoma accounting for approxi-mately 1-2% of sarcoma with an annual incidence rate of 0.8-4.1 cases per million persons per year [1, 2]. Thi Dermatofibrosarcoma protuberans (DFSP) is a rare tumor of the dermis layer of the skin, and is classified as a sarcoma.There is only about one case per million per year. DFSP is a fibrosarcoma, more precisely a cutaneous soft tissue sarcoma.In many respects, the disease behaves as a benign tumor, but in 2-5% of cases it can metastasize, so it should be considered to have malignant potential

Dermatofibrosarcoma protuberans (DFSP) is a rare skin tumor arising in the dermal layer of skin. It occurs in about 1 in 100,000 to 10 million. It may occur at any age, but it is most common in. Dermatofibrosarcoma protuberans (DFSP) is a rare slow-growing cutaneous soft tissue sarcoma that is characterized to be locally invasive with a high recurrence rate. However, it has a poor metastatic capacity. This literature review was conducted to gather evidence-based medicine knowledge regarding DFSP. The literature search was conducted by using the keywords Dermatofibrosarcoma. Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade malignant mesenchymal tumor of the soft tissue, characterized by slow infiltrative growth and common local recurrence, with rare distant metastases. We present a retrospective study of nineteen patients who were diagnosed with DFSP and operated at our institution in > 10-year period

INTRODUCTION. Dermatofibrosarcoma protuberans (DFSP) is an uncommon locally aggressive cutaneous soft tissue sarcoma. Approximately 85 to 90 percent of DFSPs are low grade, while the remainder contain a high-grade sarcomatous component (which is usually a fibrosarcoma, designated DFSP-FS) and are considered to be intermediate-grade sarcomas [] Dermatofibrosarcoma protuberans (DFSP) is a rare and poorly understood dermal fibroblastic soft tissue tumor that constitutes a difficult management problem. 1, 2 The mainstay of therapy for patients with DFSP is surgical resection. 3 However, as many as 60% of patients who are treated for DFSP may experience local recurrence, and this may be associated with substantial morbidity. 4 DFSP is.

Dermatofibrosarcoma protuberans (DFSP) is a rare but locally aggressive spindle cell neoplasm accounting for less than 2% of all soft tissue sarcomas and less than 0.1% of all malignancies. Immunohistochemical and ultrastructural studies indicate that the tumor is of a fibroblastic origin These findings revealed a rare soft tissue sarcoma known as dermatofibrosarcoma protuberans, which has an estimated incidence of 0.8 to 4.5 cases per million per year. 1 These tumors comprise roughly 6% of all soft tissue sarcomas. 2 They are superficial, slow-growing, and have a low malignant potential, with roughly 85% to 90% being low grade with a relatively good prognosis Dermatofibrosarcoma protuberans commonly presents as an asymptomatic, slowly growing, indurated plaque that may be flesh colored or hyperpigmented, followed by development of erythematous firm nodules of up to several centimeters. 1,3 Dermatofibrosarcoma protuberans may be associated with a purulent exudate or ulceration, and pain may develop as the lesion grows Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing sarcoma. DSFP has low metastatic potential but may be locally aggressive, exhibiting extensive subclinical extension and a high local recurrence rate

Dermatofibrosarcoma protuberans is an uncommon spindle cell tumor, which was originally described as a distinct clinicopathologic entity in 1924 by Darier and Ferrand [].The term dermatofibrosarcoma protuberans was coined by Hoffman [] in 1925 and, to this day, remains the preferred name among many proposed for this lesion.. Dermatofibrosarcoma protuberans typically arises in the dermis. Dermatofibrosarcoma protuberans (DFSP) represents a low-grade soft tissue sarcoma that originates from the skin dermis layer. It is a rare tumor which accounts for about 5% of soft tissue sarcoma. They can occur in all age groups and both sexes with young adults most frequently affected.

DFSP was first described by Taylor (1890). Sirvent et al. (2003) stated that, because DFSP is relatively rare, grows slowly, and has a low level of aggressiveness, its clinical significance has been underestimated. In particular, they noted that the existence of pediatric cases has been overlooked. Gardner et al.

Purpose of review: This update on the treatment options for dermatofibrosarcoma protuberans reviews data published after May 2003. These new data are discussed in the context of treatment concepts established or evolving over the past few years.. Recent findings: Because of the rarity of this disease, few papers have reported on the pathogenesis and treatment of dermatofibrosarcoma protuberans. The possible presence of dermatofibrosarcoma protuberans should always be considered in cases of recurrence of injury with histopathological diagnosis of fibroma. The histopathological diagnosis of dermatofibrosarcoma protuberans may be difficult owing to the absence of nuclear atypia and low mitotic index, requiring an immunohistochemical analysis for a definitive diagnosis Dermatofibrosarcoma protuberans: (DFSP) A type of skin tumor that begins as a hard nodule and grows slowly. DFSP is usually found in the dermis of the limbs or trunk of the body. (The dermis is the inner layer of the two main layers of tissue that make up the skin. Dermatofibrosarcoma protuberans is a rare soft tissue tumour with a very low ( 0.5%) rate of metastasis.Rates of re-excision and recurrence were determined using data from the Netherlands Cancer Registry between 1989 and 2016 The prognosis for dermatofibrosarcoma protuberans, especially if detected early, is fairly good. There are sometimes efforts to use chemotherapy to shrink the tumor. The use of imatinib, a mild drug used in various forms of chemotherapy, can sometimes produce promising results What is dermatofibrosarcoma protuberans (DFSP)? DFSP is a rare type of cancer that occurs in the skin. It develops in the dermis, which is our second layer of skin. The exact cause of it is unknown. How common is DFSP?
