Abstract
Cutaneous angiosarcomas are rare soft tissue tumours originating from hematogenous vasculature that are aggressive and carry a poor prognosis. We describe the case of a 73-year-old man with a low-grade well-differentiated angiosarcoma. Our case distinguishes itself from those previously reported in the slow progression and important delay to the presentation of 30 months and survival time of 5.5 years. Additionally, its severe clinical appearance (T2 stage) but milder pathological picture (T1 stage) is very uncommon. A repeat biopsy is warranted when results are inconclusive and there is a high clinical suspicion of angiosarcoma.

Abstract
OBJECTIVES We explored features of the angiosarcoma (AS) tumor microenvironment to discover subtypes that may respond to immunotherapy. METHODS Thirty-two ASs were included. Tumors were studied by histology, immunohistochemistry (IHC), and gene expression profile using the HTG EdgeSeq Precision Immuno-Oncology Assay. RESULTS Comparing cutaneous and noncutaneous ASs, the second group showed 155 deregulated genes, and unsupervised hierarchical clustering (UHC) delineated two groups: the first mostly cutaneous AS and the second mainly noncutaneous AS. Cutaneous ASs showed a significantly higher proportion of T cells, natural killer cells, and naive B cells. ASs without MYC amplification revealed a higher immunoscore in comparison with ASs with MYC amplification. PD-L1 was significantly overexpressed in ASs without MYC amplification. UHC showed 135 deregulated genes differentially expressed when comparing ASs from the non-head and neck area with patients who had AS in the head and neck area. ASs from the head and neck area showed high immunoscore. PD1/PD-L1 content was significantly more highly expressed in ASs from the head and neck area. IHC and HTG gene expression profiling revealed a significant correlation between PD1, CD8, and CD20 protein expression but not PD-L1. CONCLUSIONS Our HTG analyses confirmed a high degree of tumor and microenvironment heterogeneity. Cutaneous ASs, ASs without MYC amplification, and ASs located in the head and neck area seem to be the most immunogenic subtypes in our series.

Abstract
Under the umbrella of cutaneous sarcomas (CS) we include a heterogeneous group of rare, malignant, mesenchymal neoplasia, such as dermatofibrosarcoma protuberans, atypical fibroxanthoma, cutaneous undifferentiated pleomorphic sarcoma, cutaneous angiosarcoma and leiomyosarcoma. Clinical presentation and histopathological examination are the cornerstone of CS diagnosis and classification. There are scarce data in the literature in regards to the clinical and dermatoscopic characteristics of CS and the role of dermatoscopy in their early identification. We performed a literature review, aiming to summarize current data on the clinical and dermatoscopic presentation of the most common types of cutaneous sarcomas that may facilitate early diagnosis and prompt management. Based on the available published data, CS are characterized by mostly unspecific dermatoscopic patterns. Dermatofibrosarcoma protuberans, Kaposi's sarcoma, and in a lesser degree, cutaneous angiosarcoma, may display distinct dermatoscopic features, facilitating their early clinical recognition. In conclusion, dermatoscopy, in conjunction with the overall clinical context, may aid towards suspicion of CS.

Abstract
Epithelioid angiosarcoma is a rare subtype of angiosarcoma, with metastases occurring in more than 50% of cases and the lung is the most organ which is involved. Whole-body fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has demonstrated its clinical utility in the early detection of metastases in angiosarcoma. It is helpful to differentiate between benign lesions with low FDG uptake as compared to malignancies with high FDG avidity. Here, we present a rare case of a young man with epithelioid angiosarcoma, in which FDG PET/CT has demonstrated metastatic sites (especially lung metastases).

Abstract
Background Cutaneous angiosarcoma (AS) of the head and neck is a rare highly aggressive tumor, often associated with difficult local control of the disease and poor prognosis. This article describes a case of multifocal cutaneous AS of the scalp, mainly addressing its difficult surgical management and challenging reconstruction and concludes with a review of the literature. Methods A 70‐year‐old Caucasian male was referred to our hospital with a growing scalp lesion initially suspected to be benign, but later diagnosed with AS. Results The patient had tumor recurrence and a difficult reconstruction for which dermal substitutes proved very useful. Conclusion AS can mimic a benign lesion in its early stages. Skin substitutes, namely dermal templates, can be useful to meet the complex needs of reconstruction and oncological surveillance of patients with AS.

Abstract
Angiosarcomas (AS) represent a heterogenous group of tumors with variable clinical presentation. AS share an important morphologic and immunohistochemical overlap with other sarcomas, hence the differential diagnosis is challenging, especially in poorly-differentiated tumors. Although molecular studies provide significant clues, especially in the differential diagnosis with other vascular neoplasms, a thorough hematoxylin and eosin analysis remains an essential tool in AS diagnosis. In this review, we discuss pathological and molecular insights with emphasis on implications for differential diagnosis in cutaneous, breast, soft tissue and visceral AS.

Abstract
Radiation therapy is a mainstay for the treatment of primary malignancies and metastatic disease and is associated with several dermatological adverse events that are underreported in the literature. The objective of this paper was to review the literature regarding cutaneous manifestations associated with radiation therapy in order to promote awareness of the cutaneous radiation therapy-associated adverse effects. This extensive literature review was performed using the Pubmed and Embase databases. Studies were reviewed for relevance and critical evidence pertaining to cutaneous manifestations of radiation therapy. The most commonly reported cutaneous sequelae associated with radiation therapy include radiation dermatitis, non-melanoma skin cancer, radiation-associated angiosarcoma, morphea, bullous pemphigoid, lymphangioma circumscriptum, and pseudosclerodermatous panniculitis. For many of these conditions, only case reports or case series exist and there is an absence of large-scale cohort studies. Despite these limitations, this review describes the wide range of dermatological adverse events associated with radiation therapy.

Abstract
Purpose The aim of this study was to report individual surface mould multi-catheter high-dose-rate (IMM HDR) application as a salvage treatment for a head and neck angiosarcoma patient, previously treated with surgery followed by external beam radiotherapy. Material and methods A 74-year-old male reported to our center with an uncommon malignant neoplasm of blood vessels. The patient was qualified for a wide local excision (WLE) of tumor with simultaneous reconstruction using a free-flap collected from the patient's thigh. After surgery, the patient was qualified for adjuvant external-beam radiotherapy (EBRT). Volumetric arc therapy (VMAT; RapidArc®, Varian Medical Systems) was used to deliver 52.8 Gy/1.6 Gy in 33 fractions. Overall treatment time was 51 days. Six months after radiotherapy, an incisional biopsy of non-healing ulcer of the nasal bridge revealed angiosarcoma. Wide local excision with skin graft reconstruction was planned. Due to multifocal disease and lack of possibility for further margin, the resection surgery was completed after skin graft reconstruction from the right thigh. Surface IMM HDR was considered as an alternative option for further treatment. Total dose of 48 Gy (12 fractions) was planned. Results One month after surface IMM HDR, healing process of the skin was observed in the treated regions and six months later, the irradiated areas recovered. General condition of the patient deteriorated two years after diagnosis and one year after HDR. He was hospitalized to receive palliative care. Conclusions HDR brachytherapy may be a valuable option for angiosarcoma treatment. Difficult lesion location may yield non-radical surgery. Surface IMM HDR provides highly conformal plan and allow adjusting the dose to individual clinical situation.

Abstract
Cutaneous angiosarcoma (AS) is an uncommon, aggressive sarcoma whose incidence is rising because of the increasing use of radiation therapy, especially in breast cancer. The few studies on the relevance of prognostic factors, such as MYC status in cutaneous AS, have reported inconclusive findings, with some authors reporting MYC amplification only in postirradiation and lymphedema-associated AS and others reporting evidence of MYC amplification in idiopathic AS. We analyzed 17 cases of cutaneous AS (6 idiopathic AS, 10 postirradiation AS, and 1 lymphedema-associated AS) treated at our institute between 2000 and 2015. Follow-up data were available in all cases. We compared the presence/absence of MYC amplification by fluorescence in situ hybridization (FISH) and immunohistochemical (IHC) MYC overexpression in the different AS subtypes. We also investigated potential associations between MYC amplification and prognosis. MYC amplification was observed by FISH in 6 of 14 informative cases. The positive cases were all secondary AS (5 postirradiation AS and 1 lymphedema-associated AS). IHC detected MYC overexpression in 8 of 15 informative cases (7 secondary AS and 1 idiopathic AS). In conclusion, MYC amplification and MYC overexpression were detected almost exclusively in secondary AS. No associations were found between MYC amplification/overexpression and prognosis. We found MYC amplification or overexpression in a similar proportion of the patients who died and who were still alive at the end of the study. In the group of 9 patients who died, MYC was detected by FISH in 4 cases and by IHC in 5. The corresponding figures in the group of 6 patients still alive were 2 by FISH and 3 by IHC.

Abstract
Cutaneous angiosarcoma is a rare malignant tumor showing blood or lymphatic vessel differentiation, corresponding to < 2% of all sarcomas. It preferably affects elderly, with predilection for the head and neck. Diagnosis is frequently late due to the early interpretation by the patient as a benign lesion similar to ecchymosis, which explains its aggressiveness with high metastasis and recurrence rates. We report the case of an elderly man whose histopathologic diagnosis confirmed the clinical suspicion of cutaneous angiosarcoma.
