目的 进一步提高对隆凸性皮肤纤维肉瘤(DFSP)的认识,探讨正确和规范手术治疗的重要性。方法对119例隆凸性皮肤纤维肉瘤,进行临床和病理资料的回顾性分析。结果 119例中有111例(占93.3% )在入院前被误诊为良性肿瘤而行局部切除术,经补充广泛切除,病理检查最终明确局部有肿瘤残留者57例,占51.4%,其中40例(占70.2%)在查体或B超检查时未能发现残留灶;12例(占10.1%)出现纤维肉瘤样改变(DFSP-FS),其中10例见于局部切除或广泛切除后复发的病例(复发次数1-13次不等)。结论 为避免误诊,临床医师有必要进一步提高对DFSP的认识;在局部切除术后,一经病理检查确诊为DFSP,必须施行补充广泛切除以避免肿瘤残留;为减少复发,宜重视首次手术的正确治疗和广泛切除手术的规范治疗。 相似文献

Introduction and importanceDermatofibrosarcoma protuberans (DFSP) represents about 1% of soft tissue sarcomas with an estimated incidence of 0.8–5.0 cases per million per year. The involvement of DFSP in breast is very rare and very few cases have been reported in the literature. DFSP was recurred in situ, not spread to distant site. The complete surgical excision with wide, pathologically negative margins of 3 cms is the optimal treatment for primary or recurrent tumor.Presentation of caseA 46-year-old woman presented with palpable lump in the in the right breast. On ultrasonography, a lesion appeared as hypoechoic, circumscribed mass of approximately 37 mm × 30 mm in diameter in the upper central part of the right breast. The mass of right breast was demonstrated DFPS by pathologic examination. Chest computerized tomography (CT) scan and 2-[18F]-fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography (PET) showed only primary lesion in subcutaneous layer and no enlarged lymph node. The patient underwent excision of the tumor widely. There was no evidence of DFSP local recurrence after five years of follow-up of the patient.DiscussionDFSP is a rare tumor arising from dermis and subcutaneous mesenchymal tissue. Whereas, characteristic imaging feature of DFSP in the breast are not well-defined. The primary treatment for DFSP is considered to be surgical excision.ConclusionDFSP in breast is extremely uncommon and can mimic a primary breast tumor. Surgical excision with adequate resection margins is recommended to ensure local control of the disease. 相似文献

Dermatofibrosarcoma protuberans (DFSP) is a rare tumor of the skin, which has a propensity for local recurrence. Surgery is the only option of treatment and resection with wide surgical margins including the underlying fascia has become the standard treatment. Two cases of DFSP located on the trunk and forearm are presented who were managed with 3 cm tumor free lateral margins and in depth resection including underlying muscles. The patients were found to have no tumors after 3 and 4 years follow-up. This aggressive approach including excision of underlying muscles is advocated for DFSP located on the trunk or extremities to prevent local recurrence. 相似文献

There is a prevailing view that sarcomas arising in dermatofibrosarcoma protuberans (DFSP) have a higher risk of metastasis than ordinary DFSP, but these data are based on cases with variable and often suboptimal treatment. There has not been a large study of sarcomas arising in DFSP in which all cases were treated by wide local excision, thereby arguably altering outcome. Clinicopathologic features of 18 cases of sarcomas arising in DFSP treated by wide local excision and having follow up of at least 5 years were analyzed. An estimate of the proportion of sarcoma and DFSP was made. The number of mitotic figures and degree of CD34 immunoreactivity were assessed in each case. The cohort included 13 females and 5 males (age, 23-87 yrs; median, 47 yrs). The tumors involved the trunk (7), scalp (4), extremities (4), and inguinal region (3), and ranged from 1.5 to 7 cm (median, 4 cm). Sarcoma occurred de novo in 15 cases and in a recurrence in three. Sarcomas resembled fibrosarcoma (17) or malignant fibrous histiocytoma (1) and occupied between 20% and 80% of the tumor (median, 60%). Mitotic activity ranged from 2 to 16 per 10 high-power field (HPF; median 7 per 10 HPF) in the sarcomatous component and 0 to 3 per 10 HPF (median, 1 per 10 HPF) in the DFSP component. All tumors expressed CD34 in the DFSP component but only nine (50%) in the sarcomatous component. All patients were treated by wide local excision with negative margins; three additionally received radiation. Four patients (22%) developed recurrences, but none developed metastasis during the follow-up period of 62 months to 17 years (median, 81.5 mos). In contrast to earlier studies, we demonstrate that patients with sarcomas arising in DFSP do not have an increased risk of distant metastasis within a 5-year follow-up period, provided they are treated by wide local excision with negative margins. This probably reflects the fact that wide local excision results in eradication of local tumor, thereby eliminating the source for subsequent dissemination. However, we cannot completely exclude the possibility that tumors in which clear margins are achieved represent a less aggressive subset, as has been suggested for high-grade extremity sarcomas. Previous studies showing increased metastasis for sarcomas arising in DFSP should be re-evaluated to determine if, with treatment stratification, metastatic rate varies. 相似文献

Dermatofibrosarcoma protuberans. A clinicopathologic review with emphasis on fibrosarcomatous areas.
We reviewed 75 cases of dermatofibrosarcoma protuberans (DFSP) from the University of Texas M.D. Anderson Cancer Center. All accessions were examined for areas of giant cell fibroblastoma (GCF), but none was found. The 30 cases having a minimum of 5 years follow-up were studied in more detail. The histologic findings were typical of DFSP in 24 cases, whereas in six cases discrete areas with a fascicular or "herringbone" growth pattern, considered to represent fibrosarcomatous change (DFSP-FS), were evident. The mitotic rate was usually but not always higher in fibrosarcomatous areas, and occasional examples of typical DFSP demonstrated relatively numerous mitotic figures (up to 35 per 10 high-power fields). Other histologic findings of interest were the presence of melanin in two cases of DFSP and the focal presence of a distinctive type of multinucleated giant cell similar to those seen in GCF in six cases. Patients with DFSP-FS differed from those with DFSP in that they had a higher median age (56 years vs. 37 years). Tumor location was similar in both groups, with the trunk being the most common site. No significant difference in either the rate of local recurrence or the interval until recurrence between DFSP and DFSP-FS was evident; the only factor strongly related to local recurrence was adequacy of surgical margins. However, the only two patients who died of tumor, including the sole patient with distant metastasis, had DFSP-FS. We conclude that DFSP-FS deserves recognition as a variant of DFSP. 相似文献

Background: The extent of local invasion in dermatofibrosarcoma protuberans (DFSP) is often clinically difficult to appreciate, and this leads to inadequate resections. We examined the effect of inadequate initial treatment and the efficacy of wide resection.Methods: We performed a retrospective analysis of the records of 35 patients with DFSP treated at our institution (1985 and 2001). Data were analyzed with Wilcoxons ranked sum test and Fishers exact test.Results: Of the 24 patients eligible for analysis, 11 had definitive wide resection after diagnostic excisions elsewhere (primary group), and 13 had recurrent tumors after previous surgical treatment elsewhere (recurrent group). Twenty-three patients were treated with wide resection only, and adjuvant radiation was administered to one patient who had a fibrosarcoma. At a median follow-up of 54 months, patients definitively treated at our institution had a 100% local recurrence–free survival. In comparison to the primary group, recurrent DFSPs were significantly larger and deeper and occurred in the head and neck region. Five cases had bone involvement, and of these, 80% occurred in the recurrent group.Conclusions: Inadequate initial treatment results in larger, deeper recurrent lesions, but these can be managed by appropriate wide excision. Wide resection of DFSP (whether recurrent or primary) with negative histological margins predicts a superior local recurrence–free survival. 相似文献

Modified Mohs Micrographic Surgery in the Therapy of Dermatofibrosarcoma Protuberans: Analysis of 22 Patients 总被引:4,自引:1,他引:3
Background: Dermatofibrosarcoma protuberans (DFSP) is a very rare, low-grade malignant tumor. Local recurrence is frequent after incomplete resection either because of false diagnosis or inadequate standard surgical excision. This study evaluated the clinical outcome of micrographic surgery with paraffin sectioning in the therapy of DFSP.Methods: Medical charts of 22 patients with histologically confirmed DFSP treated at our institution between 1987 and 2002 were reviewed.Results: For 13 patients with primary and 9 with recurrent disease, tumor-free excision margins could be achieved, and all patients remained free of local recurrence during a mean follow-up of 54 months.Conclusions: The results of our study and a review of the literature confirm the successful and recurrence-free treatment of DFSP with micrographic surgery as the treatment of choice for this locally invasive tumor. Particularly in recurrent lesions, we recommend the use of paraffin sectioning and three-dimensional histological evaluation as an accurate additional tool for treatment optimization. 相似文献

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a relatively rare cutaneous malignancy with the potential for significant local destruction and morbidity. This neoplasm has a tendency for recurrence following excision due to its infiltrative nature. Surgical excision with wide margins has been considered the standard therapy for DFSP but has had reported recurrence rates of up to 60%. OBJECTIVE: The results of 20 patients with DFSP treated with Mohs micrographic surgery (MMS) are reported. We also reviewed the world literature on the role of MMS for treatment of this tumor. METHODS: Twenty patients between the ages of 20 and 82 years with DFSP were treated with MMS. The patients were followed for recurrences between 4 and 216 months (mean 56.4 months). RESULTS: None of the 20 patients had a recurrence of DFSP following MMS. Of 221 DFSP patients in our review of the world literature treated with MMS, only 5 (2.3%) had a recurrence. CONCLUSION: MMS is an effective treatment of DFSP. 相似文献
