Oral Pseudomyogenic Hemangioendothelioma: Case Report and Review of the Literature

AbstractPseduomyogenic hemangioendothelioma (PMH) is a vascular neoplasm of intermediate biological potential first described by Hornick and Fletcher (Am J Surg Pathol 35:190 –201, 2011). Despite its initial categorization as a malignant entity, PMH often demonstrates an indolent behavior profile, and thus was classified as a rarely metastasizing endothelial neoplasm in the 2013 WHO Classification of Tumors of Soft Tissue and Bone. It is a tumor primarily of skin and s oft tissue, with most reported cases involving the trunk or extremities. To date, only one case of PMH involving the oral cavity has been reported. Herein, we present a case of PMH involving the mandibular gingiva and vestibule of a 33-year-old female and discuss the salient features of this entity.
