Abstract
Objectives: To review the clinical presentation, diagnostic approach, treatment strategies, and outcomes of vulvar hemangiomas, and to evaluate the consistency of management practices in the absence of standardized guidelines. Eligibility criteria: We included case reports, case series, and observational studies describing vulvar hemangiomas with clinical, histological, and management data in human subjects. Reviews, editorials, and studies unrelated to vulvar hemangiomas were excluded. Information sources: Systematic searches were conducted in PubMed, Embase, Scopus, and Web of Science up to 20 February 2025, with additional citation tracking. Results: 85 studies were included. Data were synthesized narratively due to heterogeneity in the study design and outcome reporting. Most studies described symptomatic lesions presenting as swelling, bleeding, or pain, often misdiagnosed as Bartholin cysts or varicosities. Treatment varied widely, including observation, surgical excision, embolization, and medical therapies. No evidence-based guidelines were identified. Conclusions: Vulvar hemangiomas are rare and frequently misdiagnosed. While asymptomatic lesions may be observed, symptomatic cases require individualized treatment. This review highlights the need for diagnostic vigilance and the development of standardized management protocols. Further research is needed to optimize clinical outcomes.

Abstract
Angiosarcomas of the kidney and adrenal gland are rare, highly aggressive vascular neoplasms. Their genomic profile has not been systematically studied to date. We report the clinicopathologic and molecular features of six angiosarcomas centered in the kidney/adrenal gland. All patients were male adults, ranging from 58 to 77 years of age. Tumor sizes ranged from 2.5 to 22.5 cm. Half of the cases demonstrated hot spot mutations in the KDR gene, while one-third demonstrated mutations in the PIK3CA gene; both of these gene alterations being previously described, preferentially in breast angiosarcomas. In addition, two cases each demonstrated BRIP1 gene amplification, CTNNB1 and ETV6 mutations, which have not been previously reported in angiosarcoma. Notably, molecular studies were critical in establishing the correct diagnoses in three cases: one was an epithelioid angiosarcoma originally misdiagnosed as metastatic adenocarcinoma to the adrenal gland, the second was a vasoformative angiosarcoma that mimicked hemangioma, and the third was a collision tumor between a high-grade angiosarcoma and a chromophobe renal cell carcinoma which was originally diagnosed as a sarcomatoid renal cell carcinoma. In summary, angiosarcomas of the kidney and adrenal gland have a high frequency of recurrent genetic alterations, some of them being shared with other angiosarcoma subtypes, while other appear to be novel. In particular, activating hot spot KDR and PIK3CA mutations represent potential therapeutic targets for these highly aggressive cancers.

Abstract
Vascular tumors are the most common mesenchymal neoplasms of the skin and subcutis, and they encompass a heterogeneous group with diverse clinical, histological, and molecular features, as well as biological behavior. Over the past two decades, molecular studies have enabled the identification of pathogenic recurrent genetic alterations that can be used as additional data points to support the correct classification of these lesions. The purpose of this review is to summarize the available data related to superficially located benign and low-grade vascular neoplasms and to highlight recent molecular advances with the role of surrogate immunohistochemistry to target pathogenic proteins as diagnostic biomarkers.

Abstract
BACKGROUND Epithelioid hemangioendothelioma (EHE) is a malignant vascular neoplasm representing ∼1% of sarcomas. Due to its rarity, its clinical course is not well characterized and optimal treatment remains unknown. MATERIALS AND METHODS This was a retrospective review of patients with EHE treated at Stanford University between 1998 and 2020. Demographic characteristics, pathology results, treatment modalities, and clinical outcomes were collected from the electronic medical records. RESULTS A total of 58 patients had a mean age of 50.6 years and a slight female predominance (52%). Primary disease sites were liver (33%), soft tissue (29%), lung (14%), bone (9%), and mediastinum (9%). A majority (55%) had advanced or metastatic disease. Median overall survival (OS) was 16.9 years, with OS 89% at 1 year, 68% at 5 years, and 64% at 10 years. The longest median OS was associated with soft tissue sites and shortest with lung and mediastinal disease (P=0.03). The localized disease had improved median OS compared with metastatic disease (P=0.02). There was no OS difference between tumors >3 cm and those equal or smaller (P=0.85). Surgery was a common treatment (71%), while radiation and ablation were sometimes used (28% and 9%, respectively). The median time to initiating therapy of any kind was 68 days. The median time to systemic therapy was 114 days. CONCLUSIONS We report on the clinical characteristics and outcomes of patients with EHE at a large academic center. Treatment options included surgical excision, liver transplant, ablation, radiation, and systemic therapy. A subset of patients had indolent disease not requiring treatment upfront.

Abstract
In this article, the authors have reviewed all the recent news regarding how the discovery of some novel and recurrent molecular and genetic changes has modified the classification of some entities and have addressed to the description of new variants of vascular tumors. And even more important, the authors also reviewed on how these findings, in addition to gain insight into the tumoral biology, portend significant clinical consequences not only regarding to their diagnosis but also to their management and prognosis because some of these mutations are potential targets for treatment. The authors have also highlighted immunohistochemical markers can help us as a surrogate marker of those molecular alterations.

Abstract
We presented a difficult-to-diagnose case of cardiac angiosarcoma. The patient presented pericardial effusion, but cytology of the effusion was negative. Because cytological detection of angiosarcoma cells is difficult, a possibility of malignancy should not be excluded with negative cytological examination. Biopsy of cardiac mass is the best way for diagnosis.

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
We report the largest series to date (N = 6) of EWSR1-SMAD3 rearranged fibroblastic tumor. Initially described in 2018, the tumor features a marked female predominance (F:M, 5:1, mean age 44-years, median age 45.5 years; range 27-57), with most cases (5/6, 83%) arising in acral locations (4 on foot/toe, 1 on hand). One case presented on the lower extremity. The lesions presented as nodules and were composed of short, variably cellular, intersecting fascicles of uniform spindled cells in a collagenous to myxoid stroma. In four cases, the tumor abutted the epidermis without a grenz zone. In one case, there was an abrupt transition to a central, acellular hyalinized area. Two other cases had admixed smaller collagenous areas, reminiscent of collagen rosettes. One had a concentric arrangement of tumor cells around blood vessels. Mitotic activity was low (<1/10 HPFs). All were positive for ERG by immunohistochemistry and negative for CD34 (6/6). An EWSR1-SMAD3 fusion was identified in three cases tested by next-generation sequencing (3/3). Rearrangement of EWSR1 by fluorescence in situ hybridization was showed in 1/1 case. Our series reaffirms prior findings and expands the known histopathologic spectrum of this emerging entity.

Abstract
Epithelioid hemangioendotheliomas (EHE) of the liver are rare, low-malignant vascular tumors whose molecular pathogenesis is incompletely understood. The diagnosis of EHE is challenging, and the course of the disease can be highly variable. Therapeutic options for EHE are limited, including resection of primary and metastatic tumors, organ transplantation and rather ineffective systemic approaches. Driver mutations have been reported (fusion transcripts of either YAP-TFE3 or WWTR1-CAMTA1) but comprehensive molecular profiling has not been performed. Our aim was to molecularly characterize hepatic EHE to identify new molecular targets. Eight primary hepatic EHE were analyzed by next-generation sequencing using a 409-gene panel. The majority of primary hepatic EHE revealed a low number of mutations. Genes that were mutated primarily are involved in DNA repair, epigenetic regulation, signaling pathways and cell cycle control, indicating that EHE present with mutations in various functions. Although only detecting a low mutation rate, a comparison with comprehensive databases (target db V3) revealed mutations in five genes with putative therapeutical options. Therefore, our findings help to shed light on the molecular background of EHE and might pave the way to new therapeutic approaches.
