BackgroundHyalinizing clear cell carcinoma (HCCC) is a rare epithelial malignant neoplasm typically arising from the minor salivary glands. Although it has been described as a benign neoplasm, there are increasing reports of malignant features and metastases to the lungs; we present the first case of biopsy-proven spinal metastases from HCCC and an overview of the literature.Case DescriptionThis is a single-patient case report in which we used immunohistochemistry and fluorescence in situ hybridization for Ewing sarcoma breakpoint region 1 translocation to confirm the diagnosis of HCCC in a spinal metastasis. The diagnosis of metastatic HCCC was confirmed on the basis of histopathology, immunohistochemistry, and fluorescence in situ hybridization studies.ConclusionsWe present the first pathologically confirmed case of a spinal metastasis in HCCC. As increasing of metastatic HCCC arise, a reconsideration of HCCC as a potentially high-grade disease seems increasingly necessary as it may impact the current treatment paradigm.Copyright © 2016 Elsevier Inc.
