Rare occurrence of triple primary malignant tumors: Dermatofibrosarcoma protuberans, lung adenocarcinoma and papillary thyroid carcinoma in a patient with genetic evaluation.

Triple primary malignancies are rare, involving the occurrence of three distinct, unrelated cancers in a single patient, requiring a personalized, multidisciplinary treatment approach. A 69-year-old male was diagnosed with dermatofibrosarcoma protuberans (DFSP), lung adenocarcinoma, and papillary thyroid carcinoma. After amputation for DFSP, following staging and genetic evaluation, a multidisciplinary tumor board designed a tailored treatment plan, adjuvant chemotherapy for lung adenocarcinoma while monitor regularly the thyroid carcinoma via ultrasound.

Comparison of Surgical Treatment Using Mohs Micrographic Surgery versus Wide Local Excision for the Treatment of Dermatofibrosarcoma Protuberans.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive, soft-tissue sarcoma. The treatment is surgical and includes wide local excision (WLE) or Mohs micrographic Surgery (MMS). There is no consensus regarding the preferred type of surgery.

Increased frequency of germline pathogenic variants among individuals with dermatofibrosarcoma protuberans.

Purpose: To identify candidate susceptibility genes for dermatofibrosarcoma protuberans (DFSP).

Methods: All individuals with DFSP from the International Sarcoma Kindred Study ( = 3767 individuals with sarcoma diagnoses from Australia, Europe, New Zealand, and United States) and cohorts that were not ascertained based on sarcoma status or other phenotypes (Geisinger MyCode,  = 170,503 individuals, United States; UK Biobank,  = 469,789 individuals, United Kingdom) were evaluated for germline pathogenic or likely pathogenic (P/LP) variants in 156 cancer genes.

Results: There were 92 unrelated individuals with DFSP across the 3 cohorts.

Hotspots and future trends of dermatofibrosarcoma protuberans.

Objective: Dermatofibrosarcoma protuberans (DFSP) is a moderately malignant soft tissue sarcoma with localized infiltrative growth. The extensive surgical scope and high recurrence rate of DFSP brings dysfunctional, aesthetic, psychological and economic problems to patients. The aim of this study is to explore the global publication characteristics, research hotspots and future trends of DFSP over the past 32 years via an intuitive visualized way.

Recurrent Dermatofibrosarcoma Protuberans Over the Face: A Challenging Clinical Problem.

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive skin malignancy known for its high recurrence rate. It predominantly affects the trunk and extremities but can occasionally present on the face. A 47-year-old man presented with a rapidly progressive, painless swelling on the left side of his face for six months.

Racial and Ethnic Differences in Patient Presentation and Treatments in Head and Neck Dermatofibrosarcoma Protuberans.

Head and neck dermatofibrosarcoma protuberans (HNDFSP) is a rare neoplasm with a high rate of local infiltration and local recurrence but a low rate of distant metastasis. Given the limited literature on HNDFSP and existing studies pointing to possible racial and ethnic differences, further research is needed to understand important clinical correlates that may impact treatment and prognosis. The National Cancer Database (NCDB) was queried for all cases of HNDFSP diagnosed from 2004 to 2016.

Surgical Excision of Pulmonary Metastases of Dermatofibrosarcoma Protuberans.

Dermatofibrosarcoma protuberans (DFSP) is a rare malignancy of mesenchymal origin of medium-low grade with a tendency to local recurrences but not to distant metastases. We present the case of a 37-year-old male who underwent surgical resection of a 1.2 cm DFSP lesion on the left shoulder in May 2020.

Rare case of massive inguinal dermatofibrosarcoma protuberans: A case report.

DFSP is a cutaneous soft tissue sarcoma. A 35 year old male patient presented with DFSP in the inguinal region which is a rare soft tissue sarcoma which usually presents in the torso, occurring very rarely in the inguinal region. Hence in case of any swelling in the inguinal region, DFSP should be in differential diagnosis.

Ultrasound in Skin Cancer: Why, How, and When to Use It?

Background: Skin cancer is the most common cancer in human beings. Ultrasound is a powerful and non-invasive imaging technique that has expanded its use in dermatology, including in the skin cancer field. The full range of critical anatomical information provided by ultrasound cannot be deduced from a naked eye examination, palpation, or other imaging techniques such as dermoscopy, confocal microscopy, magnetic resonance imaging, or PET-CT (Positron Emission Tomography-Computed Tomography).

Dermatofibrosarcoma protuberance with a unique appearance mimicking neurofibroma arising from a conventional area.

A 21 year-old Japanese man had a rapidly growing pedunculated soft tumor in the abdomen within the past year, the base of which had persisted for 17 years. A skin biopsy of the soft part resembled neurofibroma. However, the excised specimen showed that the tumor base comprised spindle cells arranged in a storiform fashion and expanded around fat cells with a honeycomb infiltration.
