Background: Cutaneous angiosarcoma of the head and neck (cAS-HN) is a rare malignancy with poor survival. Most of the histological markers and grading were not proven to be significant for prediction of outcomes in cAS-HN. This study aimed to find prognostic clinical features and histologic markers for cAS-HN.
Material And Methods: We retrospectively analysed primary cAS-HN's seen in a single institution between 1980 and 2009. Clinical data and specific histologic characteristics were assessed. Outcome parameters were analysed using uni- and multivariate statistics.
Results: 80 patients (mean age 71.4 (SD 14.4) years, average follow-up time 55.3 (SD 74.4) months) were included. 5-year DSS rate was 62%. Univariate analysis revealed the extent of primary tumour (affecting more than one anatomical region), incomplete resection and initial metastatic disease as significant (p < 0.05) predictors for unfavourable disease specific survival (DSS) rates and time. Multivariate analysis confirmed age over 70 years, incomplete resection and initially distant metastasis influencing outcome adversely. Analysis of specific histological markers in 37 cases found patterns of growth (solid areas greater than 80%) associated with better survival (p = 0.011).
Conclusion: In conclusion age, number of affected regions, initial metastasis, complete initial resection and pattern of growth significantly affected mortality rates.

There has been noteworthy progress in molecular characterisation and therapeutics in soft tissue sarcomas. Novel agents have gained regulatory approval by the FDA. Examples are the tyrosine kinase inhibitors avapritinib and ripretinib in gastrointestinal stromal tumours (GIST), the immune check point inhibitor atezolizumab in alveolar soft part tissue sarcoma, the γ-secretase inhibitor nirogacestat in desmoid tumours, the NTRK inhibitors larotrectinib and entrectinib in tumours with fusions, the mTOR inhibitor nab-sirolimus in PEComa, and the EZH-2 inhibitor tazemetostat in epithelioid sarcoma.

Introduction: Sarcomas are relatively rare malignant tumors of mesenchymal origin, representing only about 1% of tumors in the head and neck region.
Materials And Methods: A retrospective study involved patients with sarcomas of the head and neck region who were diagnosed and treated over a 5-year period.
Results: Nine patients were included, 4 men and 5 women.

Angiosarcomas (AS) are an aggressive subtype of head and neck tumors. Current outcome research is limited to single-surgeon and/or single-institution data. This study analyzes the Surveillance, Epidemiology, and End Results program (SEER) database data to improve outcomes of head and neck AS.

While most forms of alopecia neoplastica are attributable to cutaneous metastases from visceral primary malignancies, rarely a diffuse primary skin cancer may present as alopecia. Herein, we present a case of angiosarcoma which clinically mimicked an inflammatory alopecia and was diagnosed by examination of alopecia-protocol horizontal histologic sections. A 72-year-old female presented to her dermatologist with a chief complaint of hair loss and pruritus.
