Angiosarcoma of the Temporal Bone: Case Report and Review of the Literature

Academic Article

Abstract

  • © 2019 Elsevier Inc. Background: Angiosarcomas are rare malignant tumors of endothelial origin. Nearly one half of all angiosarcomas occur in the head and neck. Temporal bone angiosarcomas are extremely uncommon. We present a case of temporal bone angiosarcoma and a review of the relevant data. Case Description: We present the case of a 20-year-old man with a painful right postauricular mass after a closed head injury. Radiologic studies demonstrated a large right osteolytic and heterogeneously enhancing mass. The patient underwent right transpetrosal craniectomy for resection. Histologic studies confirmed high-grade sarcoma. Immunohistochemical staining demonstrated a uniformly positive ERG endothelial marker, CD31 staining with cytoplasmic and membranous patterns of immunopositivity, positive nuclear staining for FLI-1, positive cytoplasmic and membranous staining for CD99 and STAT6, and negative smooth muscle actin stains in the neoplastic cells. Ki-67 staining showed ∼94% positivity in the neoplastic cell nuclei. Postoperative follow-up imaging studies demonstrated evidence of metastatic right cervical lymphadenopathy. Conclusions: Angiosarcoma of the temporal bone is extremely uncommon. In the present case report, we explored a relationship between trauma and angiosarcoma of the temporal bone. We reviewed the reported data regarding the pathogenesis, diagnosis, treatment, radiologic findings, and histologic characteristics of angiosarcoma of the temporal bone.
